We're arguing past each other then. I have no doubt that evolution is the essential thing that made us capable of unsupervised learning. That's not the central point of the debate for me. What I'm talking about is the problem of replicating that ability (unsupervised learning) in AI systems. We don't have the luxury of billions of years of evolution to do it. So we need to engineer another way.

I understood your previous comments as diminishing the sheer amount of unsupervised learning we do as humans.
