Yet high speed rail networks are practically useless for transportation within one's community (or even within most cities). In those cases, modes of transportation such as walking, skateboarding, cycling, driving are more effective. Using a C64 or C128 today would be kinda silly, but that wasn't the case in the late 1980's through mid-1990's. They were fine for many smaller tasks, and a great deal better than the alternatives if you could not afford a "real computer". Even as a glorified typewriter, a C64 was orders of magnitude better than an actual typewriter. Even as a calculator, a C64 was order of magnitude better than an actual calculator. Of course cost is the deciding factor here because computers aren't the same as transportation networks. Aside from cost high end computer is going to be better than a high end one in every case. It has physics working for it, rather than against it. Yet cost of replacement is still a factor.
