I mean, it's pretty incredible and coincidental that we evolved brains this sophisticated in the first place, out of a totally random process with selective pressure. After 13 billion years, I mean I think it's reasonable progress, but I wouldn't expect SOTA efficiency. Once you have intelligence, the evolutionary benefits are huge. There's all of a sudden not as much pressure to be efficient (well there was, for like 100,000 years, but then we invented fire and could cook, and that made getting energy/nutrition more efficient. FYI, at this point I'm just quoting from the book Sapiens)
