"computers" are huge industry now, and industry resists to innovations that requires industry players to change their processes. on the other side of the spectrum was Chuck Moore, for example, who imagines modern computers filled with many cheap and average RISC processors, and using parallel multiprocessor execution to achieve great performance. and people with expirience on 8-bit Atari, NES or C64 knows by their hearts that having specialized processors can greatly help (and it's a great PITA too ;-).
