I do wonder how far the human brain is from theoretical optimums. There is obviously something working really well, but there is also a lot of baggage that I do not doubt limits performance in some domains (cognitive) in order to preserve other basic functions (fight or flight or f*k). The biggest opponent to progress is ourselves. Even if you came up with an implant that would make humans smarter and more moral/ethical, people won't adopt it readily for fear of change. Unless AI becomes attached conservationist in nature, I'm not sure they'd retain the baggage not optimal for modern environments.
