It was pretty clear from the first moment that NFTs were of no value. The only people showing interest were speculators. It got an extremely brief flurry of interest from artists, who hoped that it might allow them to retain some kind of financial stake in their art even after it was sold, but that disappeared within days.
The AI is already producing things of production value. People use the art that comes out of it. There's a great demand for mediocre art -- product logos, book illustrations, making web pages feel less empty. It's not great art, but it's the kind of thing you'd have to pay a fair bit of money for.
It's less clear to me that the language models are worth much. Unlike art, there's no great clamor for more mediocre text. At best they're a nod in the direction of something more interesting, in a way that NFTs never did. They may yet burn out without producing anything of value, but it feels like there could be something there.
So you could be right that there's no lasting, meaningful impact. But I don't think I'd compare it to NFTs, which existed solely to push the cryptocurrency bubble a bit further. (Cryptocurrency itself did seem to have some promise, and it yet may. It seems to flounder not on a fundamental uselessness, but more on not providing sufficient value to replace the inertia existing currencies. It was attractive only to illegal transactions, and even that was swamped by pure speculation.)
