People who are against AI don’t care if it’s useless, they care it’s harmful. And you can’t systematically cause harm then say “oops, our bad” and have everything return to how it was with a snap of the fingers. The consequences of harm don’t go away when the source does.

Why must this always be the argument? It was the same with cryptocurrencies and NFTs, there is a specific type of proponent who always accuses critics of secretly being pro the technology but publicly against it due to some ulterior motive. Most people aren’t selfish lying rat bastards who think like that.
