I agree. If you look at animals it's also clear that scaling hypothesis breaks somewhen, as all measures of brain size (brain mass ratio, etc.) fail to capture intelligence. And animals have natural neutral networks. If you think about it, neutral networks have roamed the earth for millions of years - including generic algorithm for optimizing the hardware. And yet only extremely recently something like humans happened. Why? The amount of training and processing power which happened naturally through evolution beats current AI research by several orders of magnitude. Yes, evolution isn't intelligent design. But the current approach to AI isn't intelligent design either.
