I'm confused about where this argument is going, but my original point was to defend simple systems which are not based off of biology in any way other then the occasional genetic algorithm.

This is confusing given that a few posts up we were discussing how AI would improve efficiency on many different levels. Starting with your initial post in this thread. The point then is that fast simulated brains will result in more increase in efficiency than the same humans thinking about those ideas slowly. Now, the upshot is that this logic works fine even if one has an AI that isn't a simulation of a human brain but can act even like a minimally scientifically productive human.

I'm familiar with Eurisko but I don't see how it as at all relevant.
