On his new Battlestar Galactica Blog, writer Ron Moore answers fan questions, including “Why is everything so low tech when clearly these humans are so advanced?”:
The plot explanation is that following the Cylon Uprising 40 years ago, Colonial society took a giant step backwards to protect itself from the technological nightmare it had unleashed. With their enemies able to hack into virtually any network, the Colonials had to rely on stand-alone technologies that we not connected to other components. Ships like the Galactica were designed with this in mind, as well as the old military philosophy of building equipment that will function even in the most dire of circumstances. You don’t want to be using cordless phones when the ship is hit by a nuke and power is disrupted to say the least. You want something reliable and solid and preferably with a cord.The creative explanation is that high-tech ships with touch screens and computers that talk has been done to death in my opinion. Also, having magical technology that does all the work for you tends to take the human beings out of the dramatic equation. I wanted a lower-tech Galactica so that we could put people back into scifi. This show is about our characters, not about the magical technology that they use.
