Re the capabilities of neurons, the argument in Moravec's paper seem quite solid, comparing the capabilities of a bit of the brain we understand quite well, the retina, to computer programs doing the same function.

My feeling is we have enough compute for ASI already but not algorithms like the brain. I'm not sure if it'll get solved by smart humans analysing it or by something like AlphaEvolve (https://news.ycombinator.com/item?id=43985489).

One advantage of computers being much quicker than needed is you can run lots of experiments.

Just the power requirements make me think current algorithms are pretty inefficient compared to the brain.
