How long will the next AI winter last? Any predictions?

I think this one may even be longer than the last one because this cycle was entirely due to the existence of GPUs and NVIDIA. There hasn't been a single fundamental innovation. Neural networks are ancient and are unlikely to be the holy grail of intelligence after multiple decades of failed attempts. It's like running an old game on an overclocked modern desktop and claiming you invented a new game. Since we are at the absolute peak of hype now (maybe a little past the peak already), this should be the start of the bear market for AGI. The real question is if Lisp will make a comeback in the aftermath.

Recently they had some success scanning animal brain structures. For example, the fruit fly brain was completely scanned:

So it is just a matter of analyzing and re-implementing them in computer.

Neural networks are already better than human brain at matching basic items. The remaining is integrating all that shit into single general intelligence, capable of acting in real world.
