The hydrocephalus story looks a bit sketchy [0]. Also if anything brains are hyper optimized for many things (based on the many specialized sub-units). I’d bet we are essentially not unsupervised, and the sub-units of the brain are essentially fine tuned for many tasks, and hyper optimized to use all their resources incredibly efficiently (memory optimization must be intense). Not that the generative models won’t get close in some general way relatively soon, but I could see human brains being another 10-1000x more powerful than your ballpark pretty easily.
