It is overrated. It has a few uses, but it's not a generalized AI. It's like calling a basic calculator a computer. Sure it is an electronic computing device and makes a big difference in calculating speed for doing finances or retail cashiers or whatever. But it's not a generalized computing system that can basically compute anything that it's given instructions for which is what we think of when we hear something is a "computer". It can only do basic math. It could never be used to display a photo , much less make a complex video game.

Similarly the current thing that's called "AI", can learn in a very narrow subject that it is designed for. It can't learn just anything. It can't make inferences beyond the training material or understand. It can't create anything totally new, it just remixes things. It could never actually create a new genre of games with some kind of new interface that has never been thought of, or discover the exact mechanisms of how gravity works, since those things aren't in its training material since they don't yet exist.
