Someone else's use of it doesn't shoehorn it into your life; you're letting your irritation at google suggesting it every three minutes lead to saying no-one else should use it.
Generating stuff with AI takes a comparable amount of energy to playing a video game. It doesn't "delegitimize information" in any way, and doesn't devalue the "art making process", it's just a different process for arriving at something kind of similar. If the outcome were the same, it might devalue the process, but that would then be a good thing.
That only leaves alleged copyright infringement which to be honest I thought we were cool with. In any case, the OP's use of an AI image generator isn't going to lead to them not buying the art it was trained on so, again, not really a problem.
If you don't like it, don't use it.
Aww were you expecting everyone to agree with you? Sorry to have confronted you with a contrary opinion to the prevailing one.
