A while ago, we think it is like a telephone exchange, then we think it is like a computer, then we think it is like the cloud.
There's a big difference between a metaphor and a theory. No one actually thinks the brain works like a computer. It's just a useful metaphor for working memory and other psychological phenomena. Quite far removed from the neuroscience underlying it.
The true advances in interesting computer results comes not from modeling the brain, but more from low-grade mimicking of the evolutionary process.
What does this even mean?

- a-priori 17y agoI would argue that brain simulations are the ultimate "biologically-inspired algorithm".
- joe_the_user 17y agoArguably, some late-sixties AI really did think an imperative program could simulate human intelligence. It seems like there has been enough research that present day researchers don't think the brain is very much like either a single-CPU computer or "the cloud". This indicates some progress. If anything, I'd say contemporary research seems to err towards mostly doing simulation rather than attempting to understand what "general intelligence" is. This has different dangerous - if we really really wind-up able to build intelligent machines but are not able understand them, dangers that were once confined to sci-fi will become more real.
