My understanding is that for at least three years now chip feature size has been on a scale where the design software has to evolve (as in: their algorithm is simulated evolution) physical solutions to the logic-level designs to avoid unintentional self interaction, both quantum tunnelling and classical e.g. capacitance. Humans can’t do that for multi-billion transistor chips.

First off, that sounds pretty hot. :) Second, if there is reproductive variation and selection, I think it's evolution. We take our old CPU design and make a new variation, that's the reproductive variation part. We also have a market select for which designs survive via purchases or lack thereof, the selection part. It doesn't matter to me so much if a life form that hosts it, a computer hosts it or a human mind.

There's your ubiquitous singularity lurking somewhere near. Symbiosis between CPU and a Human advancing CPU's evolution. Not exactly what we were promised!
