One in the far but not unimaginably distant future, our descendants will wonder and marvel that we ever got by without genetic algorithms that lead to evolved AIs.

“How did they have time to do anything?” they will ask.

Much as we ask the same about a time before washing machines, vacuum cleaners and rapid forms of transportation.

I doubt it is possible to create an AI, but I think it is possible to create the conditions for one to evolve. That is inevitable, and not too far away I think.
