I can think of only two explanations for what brains manage to do in such small volume and on such meager power: 1) P = NP or something almost equally amazing

I can think of only two explanations for what brains manage to do in such small volume and on such meager power: 1) P = NP or something almost equally amazing is possible algorithmically, and nature found it. 2) quantum computing So I definitely concur.
