About your intuition that evolution made brains optimal... well but then there are people like John von Neumann who clearly demonstrate that the human brain can be orders of magnitude more productive without significantly higher energy costs.
My model of the human brain isn't that it's the most powerful biological information processing organ possible - far from it. In my view of the world we are merely the first species that passed an intelligence treshold allowing it to produce a technological civilisation. As soon as a species passed that treshold civilisation popped into existence.
We are the dumbest species possible that still manages to coordinate and accumulate technology. This doesn't tell you much about what the limits of biology are.
