| A bit of a further tangent but: I continue to believe that it's very likely that brains somehow leverage quantum computing. The human brain is able to accomplish computational tasks on only around 40 watts of power that destroy what we can accomplish using pretty much any known machine learning algorithm using tens or even hundreds of thousands of watts of power. Maybe our algorithms are primitive or wrong, or maybe the brain just is not a classical computer. The power of brains is so "unreasonable" that I've long suspected that there are only three possibilities: (1) Brains are quantum computers. (2) P=NP, or for a weaker form perhaps there exist large numbers of undiscovered algorithms that offer massive speed improvements over any currently known algorithm. (3) Brains or intelligence are "supernatural" or at least tap into something about nature that we fundamentally do not understand. I think option #1 is by far the most likely, especially given that brains excel most of all at search and quantum computing seems to really be able to speed up search. There is just no way classical computation can do what the human brain does on 40 watts. To me that strains credulity much more than any of the three options above. It just cannot possibly be so. |
