I found this a very thought-provoking read:
Given rapidly advancing tech, a 100 year old computer would be obsolete. Just look at what was available 100 years ago. If a computer had existed back then, it would be built with vacuum tubes and relays. Compare today's PCs and smart phones with even the mini computers, such as those from DEC and Data General, from 40 years ago.
Agreed. No question. In fact, such a device as outlined in the above linked thought experiment would be considered by some metrics to be obsolete compared to what is available *today*. But even just as an exercise I think its useful to consider what kind of computer you would want in scenarios where: * internet access is intermittent or unavailable * grid power sources are intermittent or unavailable * extremely sturdy, and... * when breaks do occur be easily repairable, ideally with readily available materials at hand I'm fascinated by the endurance of the Voyager probes, which have about as much processing power as the key fobs in our pockets. With the technology we have today, what kind of computers could we make and what software would they run that would get Voyager kinds of longevity?
