I don't know what products you're referring to. At work we rewrote our platform from scratch using AI and our users have been raving about the massive improvements we made and the new features we added (that we previously hadn't been able to due to tech debt and being short-staffed).
We had a major account that dropped us last year because the main feature they were using didn't do what they needed and it had a lot of rough edges. We thought we had lost them forever. Well, yesterday our senior account exec convinced them to sit in on a demo of the newly built product and they were floored. They loved it so much that they're coming back.
Outside of work, for my side business, my users have been raving about the features I have been shipping for the past year. Previously I would work on it casually and mostly address support issues that came up, but shied away from rocking the boat too much with anything too ambitious because it's just me and my spare time is limited. But with the help of AI the product is now more performant, more user friendly, and has a lot of valuable features it was missing before. I've been ten times more ambitious. I know several solo founders like me who have similar stories.
