Two things about this argument. Firstly, AI proponents are desperately trying to wear down your resolve any way they can, and they wouldn't be so keen to tell you it's inevitable if they weren't terrified of the push back.
Secondly, all AI slop can be expunged given the time, effort, and drive.
This "ai code/art is already everywhere and impossible to avoid so you should just relax about people using it" shit has to stop, it's not remotely true. Same exact shit as "it's the inevitable future!" or "you can't put the genie back in the bottle!!" We can literally do whatever the fuck we want
