I mean, microprocessors have been on the "impossible to bootstrap from scratch in a short period of time" for 20 years already.

More like 50. The Intel 4004 came out in 1971, and there's no way to bootstrap even that level of technology after some sort of doomsday scenario.

But I would say that processor like the Z80 are so simple and well-known and documented in the wild that they would have some chance to be bootstrapped again with what would realistically survive, one way or another, in a doomsday scenario. But yeah 20 year is too short, it's more like 40 years.
