Depends what you mean by end-user. Power users of AI aren't using these things to build applications for users, they're using them to do all the things they couldn't do as mere mortal programmers. Like the other poster detailing how they got a game running in web assembly. That's not for end-users, and even if it was they wouldn't be able to look at that and say "Wow, this is an example of AI benefitting me as an end-user" they'd just say "Wow cool, a game".
