It was an environment that would present maximal friction

March 15th, 2024

Throughout his final year of high school, Rob Henderson thought a lot about his friends, he explains in Troubled, and where they were all going:

Cristian and John said they were going to turn it all around in community college — they both planned to get good grades and then transfer to a four-year college. When they told me this plan, I thought about how we were C-minus students at best, and now that we were nearly adults, we would soon have more freedom. The marginal adult oversight we currently had would soon be nonexistent. Which meant we would go from a little bit of friction to none at all when we felt the urge to ditch class and do something reckless. Gradually, I realized the path I was on had nothing but a tragic ending and came to believe that the military was my only lifeline. It was an environment that would present maximal friction if I felt the urge to do something stupid. And it didn’t hurt that enlisting would also provide a decent income. As I write this, I’m reminded of a quote from George Orwell: “The thought of not being poor made me very patriotic.”

[…]

As a kid, I was weighed down by instability and hopelessness. The military helped to unlock my potential, because it provided a structured environment, a sharp contrast to the drama and disorder of my youth. I was surrounded by supportive people who wanted me to succeed. In this new environment, I gradually came to realize that my childhood was anomalous, and I didn’t have to let it define the rest of my life. I’d been liberated from the mistakes of my past. I believed that the external comportment I had cultivated would allow me to control my internal demons and productively channel my restless energy.

I would probably have committed at least one felony had I not been locked in the military throughout these years. For behaviors and habits to be stable and predictable, one’s environment needs to be stable and predictable. I didn’t have discipline, mentorship, healthy camaraderie, and so on back home, but I had them now.

[…]

In a very real way, simply being confined to a schedule steered me away from misconduct. Military life consists of physical training (PT), room inspections, uniform inspections, and mandatory tasks outside of standard work hours. Every aspect of existence is tightly regulated, and this is especially true for new recruits. Your life isn’t really yours. No institution is more aware of the latent impulsivity and stupidity in young people, especially young men, than the military. It has evolved into an environment in which it is very hard to do something reckless, because the consequences of failing to meet standards are both clear and severe. Major infractions like not showing up for work or failing a random drug test result in literal jail time.

I learned that so much of success depends not on what people do, but what they don’t do. It’s about avoiding rash and reckless actions that will land us in trouble. The military presses the “fast forward” button on the worst, most aggressive, and impulsive years of a young man’s life—the time when a guy is most likely to do something catastrophically stupid. Studies have found that a man’s likelihood of committing a crime peaks at age nineteen, and then gradually declines throughout his twenties.2 This has led some psychologists to describe their larger appetite for violence, risk-taking, and competitiveness as “the young male syndrome.”

[…]

For many young people, the gap between impulsive and unwise decisions and the consequences of those decisions is large. In the military, there is almost no gap at all.

Even if a young man learns absolutely nothing during a military enlistment, that’s still four to six years he spent simply staying out of trouble and letting his brain develop; the same guy at twenty-four is rarely as reckless and impulsive as he was at eighteen. The reason my life didn’t go off the rails is because I was just self-aware enough to decide to have my choices stripped from me.

[…]

Before I joined, I’d heard that the military basically becomes your parent. I found this to be true. They teach you about finance and budgeting, and supervisors would lead new guys away from doing stupid things like blowing their savings on a brand-new sports car. Instead, they’d say to buy a sensible car. Some of the guys didn’t listen, though. New members made about thirteen hundred bucks a month. It wasn’t much, but it was more than I’d ever made before.

[…]

Many people say that to do something difficult and worthwhile, they need to be “motivated.” Or that the reason they are not sticking to their goals is because they “lack motivation.” But the military taught me that people don’t need motivation; they need self-discipline. Motivation is just a feeling. Self-discipline is: “I’m going to do this regardless of how I feel.” Seldom do people relish doing something hard. Often, what divides successful from unsuccessful people is doing what you don’t feel motivated to do. Back in basic training, our instructor announced that there are only two reasons new recruits don’t fulfill their duties: “Either you don’t know what’s expected of you, or you don’t care to do it. That’s it.”

[…]

The military asked that I put myself in the service of something higher than myself. I had a seriousness of purpose that I lacked before and experienced a new feeling about who I was and who I could be in life. But it didn’t fundamentally “transform” me. It just provided conditions that prevented me from acting out the way I had as a kid.

The cost of each new generation of military aircraft rises exponentially.

March 13th, 2024

In 1984, Norman Augustine, former Under Secretary of the Army, and CEO of aerospace company Martin Marietta, published a set of “laws” about military procurement, David Hambling explains (in Swarm Troopers):

His most celebrated pearl of wisdom is Augustine’s Law 16, which says that the cost of each new generation of military aircraft rises exponentially.

[…]

Although intended facetiously, Augustine’s Law 16 has been remarkably accurate. The North American P-51 Mustang was one of the most important US fighters of WWII. Over fifteen thousand were built, at a cost of around $50,000 each in 1945 dollars ($655,000 in 2014). It was succeeded in the 1950s by the jet-powered F-100 Super Sabre at a cost of $700,000 ($6 million in 2014), ten times as expensive in real terms. The McDonnell-Douglas F-4 Phantom, which first flew in 1960, broke the million-dollar barrier, costing $2.4 million apiece in 1965 ($18 million in 2014), tripling the cost of its predecessor. Even allowing for inflation, the upwards curve is steep.

[…]

The USAF’s new F-15 Eagle, also from McDonnell Douglas, was set to replace the F-4. The Eagle was a superb aircraft, but it had reached a new high, costing in excess of $20 million ($45 million in 2014), almost tripling again the cost of its predecessor.

[…]

Extensive flying exercises found that the big twin-engine F-15 was only slightly superior to the small, cheap fighters fielded by the Russians in a dogfight. If it came to a war, the small band of F-15s would be overwhelmed by swarms of Russian MiGs. Certainly, the F-15s would be able to knock out plenty of the Russians at long range, but when the survivors closed with them, the contest would be bloody and one-sided.

The Air Force decided to go for a “high-low” mix, supplementing the elite F-15s with a large number of cheaper aircraft known as lightweight fighters. The aircraft selected for the lightweight fighter role was the single-engine F-16 Fighting Falcon, two-thirds the size of the F-15. It was to be the embodiment of a concept by fighter guru John Boyd for an austere aircraft with extreme agility that could beat anything in a dogfight. Being less complex, it would be so cheap it could be acquired in vast numbers. The F-15 with its powerful radar was the champion at long-range combat; the agile F-16 was to be the champion in the “furball” of dogfighting.

During the development process, the purity of the F-16 was slowly corrupted. It became heavier, less agile, and more expensive as more and more capabilities were added.

[…]

At $15 million in 1998 dollars ($22 million in 2014), the F-16 was cheaper than the F-15, but more expensive than anything in the previous generation, including the big F-4.

[…]

The US Navy went through a parallel experience. They also replaced the F-4 Phantom, and chose the F-14 Tomcat, a $ 38 million (1998 dollars, $ 55 million in 2014) carrier-based fighter. Like the F-15 it had a big radar and impressive long-range capabilities.

Again the F-14 was too pricey to acquire in large quantities, and the Navy took up the idea of bolstering numbers with a smaller, cheaper aircraft. They chose the F-18 Hornet, originally a failed competitor in the Air Force’s lightweight fighter competition. The F-18s costs grew from a planned $5 million to around $29 million (2003 = $37 million in 2014).

Most American prisoners belong behind bars

March 12th, 2024

Contrary to the popular narrative, Rafael A. Mangual argues, most American prisoners belong behind bars:

Contrary to the claims in Michelle Alexander’s much-discussed 2010 bestseller The New Jim Crow, drug prohibition is not driving incarceration rates. Yes, about half of federal prisoners are in on drug charges; but federal inmates constitute only 12 percent of all American prisoners—the vast majority are in state facilities. Those incarcerated primarily for drug offenses constitute less than 15 percent of state prisoners. Four times as many state inmates are behind bars for one of five very serious crimes: murder (14.2 percent), rape or sexual assault (12.8 percent), robbery (13.1 percent), aggravated or simple assault (10.5 percent), and burglary (9.4 percent). The terms served for state prisoners incarcerated primarily on drug charges typically aren’t that long, either. One in five state drug offenders serves less than six months in prison, and nearly half (45 percent) of drug offenders serve less than one year.

That a prisoner is categorized as a drug offender, moreover, does not mean that he is nonviolent or otherwise law-abiding. Most criminal cases are disposed of through plea bargains, and, given that charges often get downgraded or dropped as part of plea negotiations, an inmate’s conviction record will usually understate the crimes he committed. The claim that drug offenders are nonviolent and pose zero threat to the public if they’re put back on the street is also undermined by a striking fact: more than three-quarters of released drug offenders are rearrested for a nondrug crime. It’s worth noting that Baltimore police identified 118 homicide suspects in 2017, and 70 percent had been previously arrested on drug charges.

I’ve mentioned this before, but it bears repeating.

It’s about building the machine that builds the machine

March 11th, 2024

Before joining Tesla’s board, Antonio Gracias had invested in an electroplating plant in California, Walter Isaacson explains (in his biography of Elon), where he learned some important lessons:

Because Gracias spoke Spanish like most of the factory workers, he was able to learn from them where the problems were. “I realized that if you invest in a company, you should spend all your time on the shop floor,” he says. When he asked how they could speed things up, one of the workers explained that having smaller vats for the nickel baths would make the plating go faster. Those and other worker-generated ideas succeeded so well that the factory began turning a profit, and Gracias started buying more troubled companies.

He learned one very big lesson from these ventures: “It’s not the product that leads to success. It’s the ability to make the product efficiently. It’s about building the machine that builds the machine. In other words, how do you design the factory?” It was a guiding principle that Musk would make his own.

It established him as a politically trustworthy soldier in the eyes of the Jacobins

March 10th, 2024

Although Napoleon wasn’t present at Avignon’s capture, Andrew Roberts explains (in Napoleon: A Life), it formed the backdrop for what was easily his most important piece of writing to date, the political pamphlet Le Souper de Beaucaire:

Le Souper de Beaucaire was a fictional account of a supper at an inn at Beaucaire, a village between Avignon and Arles, which Napoleon wrote at the end of July 1793. It took the form of a discussion between an officer in Carteaux’s army, two Marseillais merchants and two citizens of Montpellier and of nearby Nîmes. It argued that France was in grave danger, so the Jacobin government in Paris must be supported because the alternative was the victory of European despots and a vengeful French aristocracy.

[…]

When Napoleon showed the manuscript to Saliceti, who was now a government commissioner in Provence, and Robespierre’s younger brother Augustin, they arranged for it to be published at public expense. It established him as a politically trustworthy soldier in the eyes of the Jacobins.

[…]

It so happened that one of Carteaux’s représentants-en-mission (political commissioners) was none other than Saliceti. Carteaux knew little about artillery and was looking for someone to take over the artillery on the army’s right flank after the wounding of its commander, Colonel Dommartin, and in the absence of Dommartin’s second-in-command, Major Perrier. Saliceti and his colleague Thomas de Gasparin persuaded Carteaux to appoint Napoleon to the post, despite his only being twenty-four years old. Napoleon suspected that his education at the École Militaire had been a deciding factor in getting him this first major break. He would later say that the artillery was short of ‘scientific men, that department was entirely directed by sergeants and corporals. I understood the service.’

[…]

By October 9 Saliceti and Gasparin had obtained for Napoleon command of all of the artillery outside Toulon. Since this was clearly going to be an artillery-led operation, the post gave him a central role.

[…]

Napoleon threw himself into the project of capturing Fort Mulgrave. By cajoling nearby towns he got together fourteen cannon and four mortars as well as stores, tools and ammunition. He sent officers further afield, to Lyons, Briançon and Grenoble, and requested that the Army of Italy furnish him with the cannon not then being used to defend Antibes and Monaco. He established an eighty-man arsenal at Ollioules to make cannon and cannonballs, requisitioned horses from Nice, Valence and Montpellier, and injected a sense of unceasing activity into his men. Constantly imploring, complaining and raging – there wasn’t enough gunpowder, the cartridges were the wrong size, trained artillery horses were being requisitioned for other uses, and so on – he sent scores of letters with demands to Bouchotte and even on occasion to the Committee of Public Safety itself, going over the heads of Carteaux and his immediate superiors.

[…]

Along with his energy and activity, his letters convey a meticulous attention to detail in everything from the price of rations to the proper building of palisades. Overall, however, his message was constant; they only had 600 milliers (just over half a ton) of gunpowder, and if they couldn’t procure more it would be impossible to start serious operations.

[…]

The result of all his hectoring, bluster, requisitioning and political string-pulling was that Napoleon put together a strong artillery train in very short order. He commandeered a foundry where shot and mortars were manufactured, and a workshop where muskets were repaired. He got the authorities in Marseilles to supply thousands of sandbags. This took significant powers of leadership – and also the kind of implicit threat that could be made by a Jacobin army officer during Robespierre’s Terror. By the end of the siege Napoleon commanded eleven batteries totalling nearly one hundred cannon and mortars.

[…]

Doppet was impressed with his artillery commander, reporting to Paris: ‘I always found him at his post; when he needed rest he lay on the ground wrapped in his cloak: he never left the batteries.’

[…]

Napoleon showed considerable personal bravery in the batteries and redoubts of Toulon, at one point picking up a blood-soaked ramrod from an artilleryman who had been killed near him and helping to load and fire the cannon himself. He believed it was this action that gave him scabies. ‘I found myself in a very few days suffering under an inveterate itch,’ he later said of this ‘terrible malady’. The cutaneous irritation stayed with him through the Italian and Egyptian campaigns and was only cured in 1802 when his doctor, Jean-Nicolas Corvisart, applied sulphur baths and by ‘putting three blisters on my chest … brought on a salutary crisis. Before that I had always been thin and sallow; since then I have always had good health.’ Some historians have argued that limited contact with the blood-stained ramrod was unlikely to have been the real cause, but Napoleon would probably have also donned the dead man’s gloves, which would have made dermatitis infection far more likely.

During one assault on an outlying fort protecting Mulgrave, Napoleon was wounded by an English gunner, who ‘ran a pike into’ his left thigh. He was trying to enter the battery by its embrasure, but fortunately reinforcements came around by the rear, entering at the same moment. Many years later Napoleon showed off to a doctor ‘a very deep cicatrix [scar] above the left knee’, recalling that ‘the surgeons were in doubt whether it might not be ultimately necessary to amputate’. In a book he wrote in exile on St Helena on Julius Caesar’s wars, Napoleon contrasted the commanders of the ancient world, who were well protected during battles, with those of the modern, concluding: ‘Today the commander-in-chief is forced every day to face the guns, often within range of grapeshot, and all battles within cannon-shot, in order to assess, see and give orders, as the view is not wide enough for generals to be able to keep out of the way of bullets.’ One of the accusations made by his detractors was that Napoleon wasn’t personally brave. ‘Cowardice had of late years been habitual to Bonaparte,’ wrote the English writer Helen Williams in 1815, for example. This is absurd; not only do cowards not fight sixty battles, but Napoleon came near death several times between battles too, while reconnoitring close to the enemy. The number of people killed near him and the bullet that hit him at the battle of Ratisbon are further testaments to his great physical bravery. Napoleon’s troops appreciated his courage and his ability to magnify their own. When all the gunners trying to establish a battery of cannon within a pistol shot of Fort Mulgrave were killed or wounded, Napoleon christened it ‘Hommes Sans Peur’ (Men Without Fear) and thereby continued to receive volunteers to man it. Nobody better understood the psychology of the ordinary soldier.

[…]

By mid-November he had surrounded Fort Mulgrave with batteries, and on the 23rd he captured its British commander, General Charles O’Hara, who had tried to counter-attack from it in a sortie and spike the French guns of one of them. ‘General Dugommier fought with true republican courage,’ Napoleon reported of that action. ‘We recaptured the battery … The guns of the Convention were un-spiked in sufficient time to increase the confusion of their retreat.’69 It was very rare to be able to repair guns that had had metal spikes hammered into their firing mechanisms, let alone quickly, and it was a sign of the professional pitch to which Napoleon had trained his men.

At one o’clock on the morning of Tuesday, December 17, 1793, Dugommier put Napoleon’s plan of attack on Toulon into action. A column under Claude Victor-Perrin (later Marshal Victor) got beyond the first line of defences at Fort Mulgrave, but faltered at the second. At about 3 a.m. Dugommier sent in the next assault of 2,000 men in the teeth of driving rain, high winds and lightning strikes. Led by Napoleon, whose horse was shot from under him, and Captain Jean-Baptiste Muiron, this assault finally took the fort after heavy hand-to-hand fighting. Napoleon then proceeded to pour heated cannonballs onto the Royal Navy vessels across the harbour below. The memory of the explosion of two Spanish gunpowder-ships stayed with him for the rest of his life. Decades later he recalled how ‘The whirlwind of flames and smoke from the arsenal resembled the eruption of a volcano, and the thirteen vessels blazing in the roads were like so many displays of fireworks: the masts and forms of the vessels were distinctly traced out by the flames, which lasted many hours and formed an unparalleled spectacle.’ He was exaggerating – only two ships caught fire rather than the whole fleet – but the effect was nonetheless dramatic.

[…]

Great and deserved benefits flowed to Napoleon from the victory at Toulon. On December 22 he was appointed brigadier-general and inspector of coastal defences from the Rhône to the Var. Saliceti brought him to the attention of the senior politicians Paul Barras and Louis-Stanislas Fréron, but best of all, as he later put it, Toulon ‘gave him confidence in himself’.

Rarely in military history has there been so high a turnover of generals as in France in the 1790s. It meant that capable young men could advance through the ranks at unprecedented speed. The Terror, emigration, war, political purges, disgrace after defeat, political suspicion and scapegoating, on top of all the normal cases of resignation and retirement, meant that men like Lazare Hoche, who was a corporal in 1789, could be a general by 1793, or Michel Ney, a lieutenant in 1792, could become one by 1796. Napoleon’s rise through the ranks was therefore by no means unique given the political and military circumstances of the day. Still, his progress was impressive: he had spent five and a half years as a second-lieutenant, a year as a lieutenant, sixteen months as a captain, only three months as a major and no time at all as a colonel. On December 22, 1793, having been on leave for fifty-eight of his ninety-nine months of service – with and without permission – and after spending less than four years on active duty, Napoleon was made, at twenty-four, a general.

[…]

During the Piedmontese campaign Napoleon received official confirmation of his promotion to brigadier-general, which required him to answer the question ‘Noble or not noble?’ Very sensibly, given that the Terror was still raging, he answered, technically untruthfully, in the negative.

One of their friends was firing her weapon, and it suddenly jammed

March 8th, 2024

Rob Henderson fills the first part of Troubled with stories from his childhood in foster care, until he gets adopted by a couple that gets divorced. Then his adopted Mom brings home a “friend” named Shelly, who becomes a second mom. They don’t feel safe, so they decide to learn to shoot:

Shelly and Mom had met up with several of their friends at an outdoor shooting range. They’d gone once before; this was their second time. One of their friends was firing her weapon, and it suddenly jammed. As she tried to figure out what was wrong, she carelessly moved the pistol around. Suddenly, the gun fired. Shelly was standing fifteen feet away, talking to a man and his young son. The bullet went straight into her lower back. Had Shelly not been standing there, the bullet would likely have killed the boy.

They were barely able to make ends meet before Shelly was disabled:

At last, Shelly had received a large insurance settlement from the shooting. She and Mom never mentioned the specific amount. I figured it was a few hundred thousand dollars, given what they bought: a new truck for Shelly, a Ford Mustang for Mom, and a motorboat they kept docked at a marina at Shasta Lake. In Red Bluff, having a new boat and a new Ford Mustang was really something.

Mom and Shelly also bought three houses in Red Bluff. One was for us to move into and two were investments to “flip.” They had agreed that the family should move into another home as a way to “start over.” But they strongly disagreed about what to do with the rest of the insurance settlement.

[…]

Mom and Shelly expected to make a lot of money by selling the other two homes they’d bought. These houses required some upkeep, and I wanted to help out, so I’d stop by both homes every week to rake the leaves and mow the lawns. Shelly explained that both houses would likely be sold within two or three months at the most, and I didn’t mind doing the extra work for that amount of time.

But three months passed, and there were no buyers.

[…]

“I would lie awake in bed at night for months, because I knew this day would come,” Mom said.

We were sitting in the living room of the biggest house I had ever lived in, and I learned that it had been a temporary dream. Eight months had passed, and the two houses Mom and Shelly had intended to flip had still not sold. Shelly and Mom had run out of money. The year 2005 was the right time to invest in houses in California, they said. But not 2006. They explained that all our homes were being foreclosed, and that we had to leave Red Bluff.

What the will and ambition of a ‘kid’ can do with the experience and aptitude of a GOAT

March 7th, 2024

Jake Paul is set to fight former heavyweight champion Mike Tyson in a boxing match that will be livestreamed on Netflix, on July 20, from the AT&T Stadium in Texas:

“It’s crazy to think that in my second pro fight, I went viral for knocking out Nate Robinson on Mike Tyson’s undercard,” Paul said. “Now, less than four years later, I’m stepping up to face Tyson myself to see if I have what it takes to beat one of boxing’s most notorious fighters and biggest icons. Within just two and a half years of founding MVP, we’re about to produce the biggest fight in history, a fight in the biggest NFL stadium in the US, broadcast live, on the biggest streaming platform in the world – a testament to all we’ve accomplished in such a short amount of time. Whether you’re tuning in on Netflix or showing out in person, whether you’re team Paul or team Tyson, or whether you’re a lifelong boxing fan or watching your first fight, you’re not going to want to miss this event. I could not be more excited to make this amazing fight available to all Netflix subscribers alongside the hardest hitter of all time, Mike Tyson, on Saturday, July 20th. My sights are set on becoming a world champion, and now I have a chance to prove myself against the greatest heavyweight champion ever, the baddest man on the planet and the most dangerous boxer of all time. This will be the fight of a lifetime.”

“I’m very much looking forward to stepping into the ring with Jake Paul at the AT&T Stadium in Arlington, Texas,” Tyson said. “He’s grown significantly as a boxer over the years, so it will be a lot of fun to see what the will and ambition of a ‘kid’ can do with the experience and aptitude of a GOAT. It’s a full circle moment that will be beyond thrilling to watch; as I started him off on his boxing journey on the undercard of my fight with Roy Jones and now I plan to finish him.”

A helicopter is necessarily a complex, delicate, and expensive piece of equipment

March 6th, 2024

David Hambling explains (in Swarm Troopers) the history of quadcopter drones:

A helicopter is necessarily a complex, delicate, and expensive piece of equipment. This is because steering involves changing the angle or pitch of the rotor blades, which needs an elaborate mechanical arrangement. The quadrotor has four sets of blades, and steers and maintains stability simply by speeding up or slowing down different rotors. Without modern electronics, it would be impossible; with them it is easy.

Modern multirotors date back to the late 1980s with the Gyrosaucer toy produced by Japanese company Keyence. However, modern developments tend to be traced back to US engineer Mike Dammarm, who developed his first battery-powered quadcopter in the early 90s. This was marketed by Spectrolutions Inc. as the Roswell Flyer in 1999 and later adapted into the Draganflyer, a range which is still going.

Multicopters multiplied, and the big breakthrough came in 2010 when Parrot produced their first AR.Drone. This was hailed as a fantastic toy: a helicopter sending back video via Wi-Fi which you control with an iPhone. The AR.Drone was a bestseller, and the world woke up to the potential of multicopters.

[…]

Multirotors have a couple of major advantages over fixed-wings. For one thing, they can operate indoors, going through buildings, tunnels, and bunker complexes. And they give a more stable view than a moving fixed-wing.

Electric regional air mobility will disrupt aviation from below

March 5th, 2024

Electric regional air mobility will disrupt aviation from below, Michael Barnard argues:

Jet engines especially became more and more efficient. At least, as long as they were flying at 38,000 feet at optimal cruising speed. Modern large diameter jet engines are miracles of engineering, turning a full 50% of their fuel’s energy into forward motion under those conditions. However, when taxiing or waiting on a runway or even taking off, it’s like pouring kerosene onto the tarmac. The economics of the engines favor longer flights.

In the USA, where so many smaller aircraft were manufactured, there was another duck through the windshield, product liability. The legal environment of the era allowed virtually unlimited liability for airframes even decades after manufacturing. Insurance costs sky rocketed, many small aircraft manufacturers went out of business and larger firms stopped making smaller aircraft.

This was recognized and Congress passed the 1994 General Aviation Rehabilitation Act or GARA, which limited airframe liability to 18 years. With GARA, smaller aircraft started being produced again, albeit in smaller numbers.

[…]

The combination meant that although there are over 5,000 airports in the United States and thousands more in Europe, under 1% of them service over 70% of passengers. Once a business model is baked in, it takes something disruptive to transform it.

[…]

But why are electric airplanes cheaper to fly? For the same reason that electric cars are cheaper to drive. Electric drive trains are vastly more efficient than ones that burn fuel. While the 50% efficiency of modern jet engines is amazing and modern gas turbine aviation engines see that efficiency at optimal speeds, battery electric aviation drive trains are 95% efficient. Further, they are 95% efficient or more when rolling around on runways or sitting still. Pre-flight checks with battery electric aircraft don’t need to keep the propellor turning, something that is causing confusion on small airfields the first few times electric aircraft fly there.

And the simplicity of battery electric drive trains reduces maintenance costs as well. Instead of fuel tanks, fuel pumps, fuel lines, complex engines, exhausts, radiators and lubrication systems with many, many moving parts, electrons flow along wires from a battery to an electric motor that turns the propellors, with a single moving part in the motor. This significantly reduces the duration of all maintenance and inspection activities, allowing the plane to fly more hours with less human intervention.

And simple, battery electric, fixed wing aircraft will be cheaper to certify in the future. At present they are novel, but civil aircraft certification is an n times n safety cross check, with every combination of conditions having to be validated in manufacturing and flight tests before NASA or EASA will allow passengers to be carried. With electric aircraft, there are a lot fewer n times n combinations because there are so many fewer moving parts and sub-systems.

This doesn’t apply to the urban air mobility Jetson dreams of electric vertical take off and landing aircraft by the way. They are complex, have multiple novelties and many more failure conditions, so certification is likely to be US$1.5 billion per machine, money that companies like Archer and Joby don’t have and realistic assessments of their business cases don’t support. More on that in a future article.

Battery energy density is not as significant a constraint as many have been assuming. Yes, batteries carrying the same energy as aviation fuels are much heavier than the fuels, but the efficiency cuts into that. With current energy density and smaller aircraft, ranges of over 200 miles are easily achievable. With CATL’s new condensed matter batteries, shipping this year, double that range with the same weight is viable.

[…]

Automating aircraft flight is actually easier than automating driving to work. Airport aprons and runways are carefully controlled environments with many fewer moving vehicles, much lower speeds and no children on tricycles. Once in the air, it’s actually quite hard to hit anything except the ground. There isn’t a lot up there and there’s a lot of room in all directions to go around anything which shares airspace. Autopilots have been able to land and takeoff for a long time and big jets frequently use it, especially in low wind, low visibility circumstances. although there is still plenty of pilot involvement and oversight.

[…]

The lingua franca of air traffic control will change from English to computerese, with humans overseeing the process.

When that occurs, the pilots can leave the cockpits and oversight can be from the ground. This is starting with smaller cargo aircraft flying carefully designed low-risk routes. No school yards will be overflown for years.

How scrappy and non-Boeing-like were the SpaceX crew on Kwajalein?

March 4th, 2024

How scrappy and non-Boeing-like were the SpaceX crew on Kwajalein?, Walter Isaacson asks (in his biography of Elon):

In early 2006, they planned to conduct a static fire test, one that ignites the engines briefly while the rocket stays attached to the launchpad. But when they began the test, they discovered that not enough electrical power was reaching the second stage. It turned out that the power boxes designed by Altan, the goulash-cooking engineer, had capacitors that could not handle the juiced-up voltage the launch team had decided to use. Altan was horrified because the window the Army had given them for the static test ended four days later. He scrambled to put together a save.

The capacitors were available in an electronics supply house in Minnesota. An intern in Texas was dispatched there. Meanwhile, Altan removed the power boxes from the rocket on Omelek, jumped on a boat to Kwaj, slept on a concrete slab outside of the airport waiting for the early-morning flight to Honolulu, and made the connection to Los Angeles, where he was picked up by his wife, who drove him to SpaceX headquarters. There he met the intern, who had arrived from Minnesota with the new capacitors. He swapped them into the faulty power boxes and rushed home to change clothes during the two hours it took for the boxes to be tested. Then he and Musk jumped into Musk’s jet for the dash back to Kwaj, taking the intern with them as his reward. Altan hoped to sleep on the plane—he had been awake for most of forty hours—but Musk bombarded him with questions on every detail of the circuitry. A helicopter whisked them from the Kwaj airstrip to Omelek, where Altan put the repaired boxes onto the rocket. They worked. The three-second static fire test was a success, and the first full launch attempt of Falcon 1 was scheduled for a few weeks later.

It taught him the importance of morale, logistics and leadership more powerfully than any number of academic lectures

March 3rd, 2024

The month after Louis XVI’s execution, Andrew Roberts explains (in Napoleon: A Life), Napoleon obtained his first significant command:

He was put in charge of the artillery section of an expedition to ‘liberate’ three small Sardinian islands from the Kingdom of Piedmont-Sardinia under Paoli’s nephew, Pier di Cesari Rocca, whom he privately derided as a ‘clothes-horse’.

[…]

They mutinied, and so the entire expedition was aborted by Rocca. A furious Napoleon was forced to spike his own cannon and throw his mortars into the sea.

[…]

It was an inauspicious start for the career of the new Caesar, but it taught him the importance of morale, logistics and leadership more powerfully than any number of academic lectures.

Life without a state is dominated by custom

March 2nd, 2024

Mark Koyama notes that his most downloaded academic paper on SSRN is a yet to be published book chapter on the political economy of Frank Herbert’s Dune:

We should first ask: do fictional universes need a political economy that makes sense? Absolutely not. But to have lasting value, I think it helps that they at least ask important political economy questions.

An episode of the Rest is History, Romans in Space: Star Wars, Dune and Beyond touch on these issues. Holland and Sandbrook note that the original Star Wars trilogy were given a patina of sophistication and historical depth by references to the “old republic” and the “senate”. Star Wars didn’t have a coherent political economy, but these hints gave viewers enough material to reconstruct their own imaginary histories. The problem with the prequel trilogy (the dire Disney remakes have different problems) is that they filled in the backstory and they did so in a particularly flat and inept way.

[…]

Paul Atreides is the quintessential “great man”. One of what the 19th century historian Thomas Carlyle called

“…the leaders of men, these great ones; the modellers, patterners, and in a wide sense creators, of whatsoever the general mass of men contrived to do or to attain….”

[…]

The intellectual depth of Dune as a novel comes from Herbert asking: what happens to a society that gets its great man or hero? Herbert’s answer is

“No more terrible disaster could befall your people than for them to fall into the hands of a Hero”

This is why David Lynch’s 1984 adaptation fails. In that adaption Paul really is the promised one: his victory makes it rain on Arrakis. There is no sense of the tragedy that inevitably accompanies a fulfilled prophecy.

So why does Paul fail? I would argue that he inevitably fails because he cannot overcome fundamental institutional and geopolitical constraints that he confronts. While this is, of course, the message of Dune Messiah, more can be said about these institutional constraints.

The political economy of the galactic empire is a form of what Douglass North, John Wallis, and Barry Weingast term “limited access orders”. Limited access orders are a form of government that achieve a measure of peace and society order through the creation of economic rents for elites.

[…]

Like oil riches, spice produces a resource curse. It leads to the concentration of autocratic power both on the planet and in the galaxy at large. While Harkonnen rule is clearly the most oppressive, the Atreides also rule the planet in an authoritarian manner. The empire Paul conquerers following his victory at the end of the first novel is at least as oppressive and even more violent than the previous Corrino empire.

In Herbert’s novels, history follows cyclical laws which humans can bend but not overcome. The Fremen freedom fights are destined to become invader and oppressors of other planets. Ecological and geographic factors weigh heavily as does Herbert’s Jungian understand of human psychology and myth. Together this saves the novel from being pure escapism.

[…]

As I note in my article, we can view the Harkonnens and the Fremen as representing two polar forms of organization. The Harkonnen represent the brutal leviathan state. They are associated with slavery, torture, and oppression. Through history despotisms, such as that of the Harkonnen’s, have been a common though extreme form of government.

In contrast, the Fremen represent a society without a state. Far from being a libertarian utopia, however, life without a state is dominated by custom (“water debt”, “the bond of water” etc.). And Fremen customs are harsh and unforgiving as the desert of Arrakis.

The Atreides, particularly Duke Leto, offer a possible middle ground. I think of this as roughly corresponding to Daron Acemoglu and James Robinson call “the narrow corridor” between rule by society and rule by the state.

[…]

In Dune Messiah, however, and in the other sequels, this sense of hope is shattered. The liberation offered by Paul results in a new and insidious theocratic despotism.

This can explain why Dune is so popular whereas the sequels that Herbert wrote have a much smaller and more niche following. The former provides a conventional heoric narrative. In the latter, structural and societal forces dominate, and the consequences of Paul’s heroic quest are transitory or malign.

We give education more importance than we should

March 1st, 2024

Rob Henderson opens Troubled with these words:

As someone who never really had one, maybe I am the least qualified person to defend the importance of family. But as someone with more education than I ever expected to receive, maybe I’m more qualified to say we give education more importance than we should.

[…]

I’ve come to understand that a warm and loving family is worth infinitely more than the money or accomplishments I hoped might compensate for them.

[…]

Unstable environments and unreliable caregivers aren’t bad for children because they reduce their future odds of getting into college or making a living; they are bad because the children enduring them experience pain — pain that etches itself into their brains and bodies and propels them to do things in the pursuit of relief that often inflict even more harm.

[…]

In one of my classes at Yale, I learned that eighteen out of the twenty students were raised by both of their birth parents. That stunned me, because none of the kids I knew growing up was raised by both of their parents.

[…]

Even though public assistance in Denmark is widely available and university education is free, disparities in test scores and educational mobility between children raised in wealthy versus low-income families are virtually identical to the US.

[…]

Even when you present opportunities to deprived kids, many of them will decline them on purpose because, after years of maltreatment, they often have little desire to improve their lives.

[…]

An important clue comes from a widely cited 2012 paper in the scientific journal Developmental Psychology. A team of psychologists found that compared to children raised in wealthier families, children raised in lower-income families are no more likely to engage in risky behaviors or commit crimes as adults. However, compared with children raised in stable environments, children raised in unstable environments are significantly more likely to engage in harmful or destructive behaviors later in life. Holding family income constant, the researchers found that the association between childhood instability and harmful behaviors in adulthood remained significant.

[…]

I scored well into the top 1 percent of the most unstable childhoods in the US.

[…]

Given the choice, I would swap my position in the top 1 percent of educational attainment to have never been in the top 1 percent of childhood instability.

[…]

I’ve come to believe that upward social mobility shouldn’t be our priority as a society. Rather, upward mobility should be the side effect of far more important things: family, stability, and emotional security for children. Even if upward mobility were the primary goal, a safe and secure family would help achieve it more than anything else.

AI is now remorselessly generating tragedy

February 28th, 2024

The amount of AI-generated content is beginning to overwhelm the internet, Erik Hoel argues:

Or maybe a better term is pollute. Pollute its searches, its pages, its feeds, everywhere you look. I’ve been predicting that generative AI would have pernicious effects on our culture since 2019, but now everyone can feel it. Back then I called it the coming “semantic apocalypse.”

[…]

Now that generative AI has dropped the cost of producing bullshit to near zero, we see clearly the future of the internet: a garbage dump. Google search? They often lead with fake AI-generated images amid the real things. Post on Twitter? Get replies from bots selling porn. But that’s just the obvious stuff. Look closely at the replies to any trending tweet and you’ll find dozens of AI-written summaries in response, cheery Wikipedia-style repeats of the original post, all just to farm engagement. AI models on Instagram accumulate hundreds of thousands of subscribers and people openly shill their services for creating them. AI musicians fill up YouTube and Spotify. Scientific papers are being AI-generated. AI images mix into historical research. This isn’t mentioning the personal impact too: from now on, every single woman who is a public figure will have to deal with the fact that deepfake porn of her is likely to be made. That’s insane.

[…]

YouTube for kids is quickly becoming a stream of synthetic content. Much of it now consists of wooden digital characters interacting in short nonsensical clips without continuity or purpose. Toddlers are forced to sit and watch this runoff because no one is paying attention. And the toddlers themselves can’t discern that characters come and go and that the plots don’t make sense and that it’s all just incoherent dream-slop. The titles don’t match the actual content, and titles that are all the parents likely check, because they grew up in a culture where if a YouTube video said BABY LEARNING VIDEOS and had a million views it was likely okay. Now, some of the nonsense AI-generated videos aimed at toddlers have tens of millions of views.

[…]

For the first time in history developing brains are being fed choppy low-grade and cheaply-produced synthetic data created en masse by generative AI, instead of being fed with real human culture. No one knows the effects, and no one appears to care.

[…]

That is, the OpenAI team didn’t stop to think that regular users just generating mounds of AI-generated content on the internet would have very similar negative effects to as if there were a lot of malicious use by intentional bad actors.

[…]

Since the internet economy runs on eyeballs and clicks the new ability of anyone, anywhere, to easily generate infinite low-quality content via AI is now remorselessly generating tragedy.

You have to fire a lot of unguided weapons to score a hit

February 27th, 2024

The implications of the lethal, portable drones for ground combat have not yet been worked out, David Hambling notes (in Swarm Troopers):

Soldiers can see the enemy at a distance and attack them with incredible precision. If someone is shooting at you with machine guns or rockets, you can hide behind a wall or in a hole. There is no way of taking cover from LMAMS short of being inside a closed bunker. It can fly around to attack from any direction and can dive into trenches. This makes it unique, and the tried and tested tactics of previous decades will have to be revised. Lying flat and keeping your head down may simply make you an easier target.

In the future, firefights with rifles may become as rare as stabbing with bayonets. The real action may take place at longer ranges without any face-to-face contact at all.

[…]

You have to fire a lot of unguided weapons to score a hit. For rifles and machine-guns, a figure of twenty thousand rounds or more is often quoted for every casualty. Artillery and mortars fire hundreds of rounds, tearing up vast areas of landscape without hitting a target. Guided weapons are different. From their first use in the 1960s, laser-guided weapons were hitting the target more than half the time. With such weapons, range is irrelevant: a target is as easy to hit from two miles away as from two hundred yards. A squad with twenty LMAMS is likely to score close to twenty hits — which may be on vehicles, firing positions, or individuals.
