What if it ends up in a USB scenario--fewer wires, but running at a higher speed? 4-8x smaller word size to get +10e6 sounds like a good trade. Just think, Z80s & 6502s coming back into fashion. This time, turbo-charged!

Chuck Moore was kind of on that beat already with his GreenArrays chips.

It will definitely be a while, but maybe not such a long one.
