When will computer hardware match the human brain? (1998) • Hacker News Board

The estimate for how many operations per second the brain does is quite a wild guess. It starts out very reasonable, estimating the amount of information the eyes feed to the brain. But from there on it's really just a wild guess. We don't know how the brain processes visual input, we don't know what the fundamental unit of processing in the brain is, or if there is one.

It is more than a wild guess, it is a guess based on the outdated perceptron model of the brain.

Active dendrites the that can do operations like xor before anything reaches the soma, or use spike timing, once again before the soma are a couple of examples.

SNNs, or spikey artificial NNs have been hitting limits of the computable numbers.

Riddled basins as an example, which are sets with no open subsets. Basically any circle you can draw will always contain at least one point on a boundary set.

This is a much stronger constraint than even classic chaos.

While I am sure we will continue to try to make comparisons, wetwear and hardware are cheese and chalk.

Both have things they are better at and neither is a direct replacement for the other.
