That was a good read, thanks for posting! I suspect in 50 years it will become much clearer what the 50 year computer is. The leading edge still moves at a blistering rate, but computing devices are so widespread now that eddies full of slower moving technology are inevitable. I’m not sure the 50 year computer will happen on purpose, either. Just as likely, a community forms around some gadget that was made for another purpose, and in its afterlife it turns out to have been unusually well designed. Consider the surviving typewriters. Typewriters used to break down all the time. We had typewriter repairmen. The typewriters that remain were lucky: well designed, well maintained, well kept. A lot of bad typewriters are rusting in landfills.
