Human brains think in 11 different mathematical spaces. Generally in Artificial intelligence that would be interpreted as an 11-dimensional matrix, or maybe an 11-dimensional tensor. That is a huge thing because it reveals an intimate detail of the structure, the other major thing is that there are so many neurons . . . Which is probably the biggest barrier at the moment, but quantum computing is on its way, so we are much closer than many people realize, in my opinion, to simulating the human brain or better.
