Basically speeds up everything...whether you think that is positive or not really depends on your imagination and biases more than anything. I'll use it for things I think are positive. It's like asking what's positive about a hammer. It's just a tool...a transformative tool...it turns your hand into a metal smasher. That doesn't sound positive but it's what you do with it that's positive or negative.

Personally, I believe AI will have a very beneficial impact on society. But, I do agree with it being overhyped, atm. It's nowhere near developed enough to have such an impact.
