Probably even less if you exclude benefits from AI that could be achieved with more pedestrian solutions but now that AI is hot they are suddenly not as flashy on powerpoints. Even then I think a lot of those projects have their benefits severely exaggarated because people who propose them then feel pressed to show benefits or embarass themselves. Even if you exclude those projects, I suspect a lot of projects are simply to "get ball in the game", to build a capability even before there is real need to be able to react to competition. Now, the value of that capability doesn't seem so much, this probably leads to many cut projects.

Still, probably beats blockchain. There was a time when I heard a blockchain project being awarded almost every other month at the companies I worked for and I still wait for ANY single one of them to do anything useful.
