The designs are smart. The CPUs themselves are still dumb, which is precisely the reason why speculative execution bugs exist. It's magic up until the point all the tricks spill out. In the end, it's always just logic gates wired together to do certain things — whether it's a Z80 or an M2 Max. All this layered complexity is simply the product of 50 years of iterative improvements.
