> It's incredibly parallel, few operations happen linearly. Even modern GPUs don't really match that. Modern GPUs aren't even close: neither in terms of degree or in kind. A GPU does a lot of linear operations in parallel, but in the brain all the "compute units" are interacting with each-other in real time.
