We are NOT close to AGI.
* Fancy Markov chain (LLM) is not AGI.
* Stable diffusion style of image generation is NOT AGI.
* Fancy computer vision is NOT AGI.
Honestly, I don't think we are any closer to AGI. What we are seeing is the peak of "fancy tricks" for computer generated artifacts.
Wild speculation. The human brain is still pretty much a black box.
> Would "feelings" improve decision accuracy in artificial systems?
Hard to tell, since we haven't observed any cases of sentient A.I. (able to feel). The only general intelligence we know (humans) have feelings as one of the most prominent features, so much so that "accuracy" is not the main driver for any given human... far from it. I don't know of any human that couldn't in one way or another be classified as "irrational".
