I always expected/hoped for more diversity in the CPU space. Instead, the alternatives sorta died one by one. (After learning how hard semiconductor factories are to build/revamp this was maybe foreseeable.) Did anybody have 5 Ghz as the "max" cpu frequency on their bingo cards? Actually, I remember touring an Intel fab. around 99/00. The guide (an engineer) was pretty sold they were "going to soon max out silicon for CPUs and have to move to germanium" based chips. (Apparently it's too expensive to this day.) Older, I seem to remember Feynman being pretty optimistic about quantum computers? But that might just have been my takeaway.
