Ask HN: How much benefit your AI solutions give?

I am working as a data scientist on a financial institusion for more than five years, and here is a thing that make me scratch my head. Are we in a bubble in widely understand AI task? I observe tendency of implementing AI solution whenever it is possible but I did not see for a very long time how much benefit does it gave. What do you think, from you perspective, it is a thing? Imo, estimation of additive value should be the very first thing that is done before ever think about implementation.
