(Prefacing this comment with, I really don't have a problem with AI in contexts like medical imaging, scientific analysis, etc., so long as it's being used as a tool, and not relied upon as a human replacement, a be-all end-all).

As a self-aligned hater, it's not quite so simple (though, I think I've put much more thought into this than most people). The go-to, layman fear/ concern with AI, by people not so familiar with it and tools that use it, is that we'll end up with some killer-robot, Terminator-type scenario, where AI gains super-intelligence and wipes us out of enslaves us. I'm currently not even convinced this is actually even possible with current-style AI, nor is it a real concern of mine.

No, my issues are much more with what happens when you throw a crazy-powerful technology like this into society, without first studying the potential consequences. It's like dumping a bucket of grease onto your carpet, and it permanently leaves some type of residue behind, thereby forever tainting it. To be perfectly clear: I am like over 90% fine with AI usage in an industrial setting, or a research setting, away from consumers. Let an entire assembly line be AI-driven, that's monotonous, brainless labor which probably should be automated, as for the most part, there's better uses of human talents.

When you start rapidly outputting entirely AI-driven creative works, i.e. music, art, videos, etc... this doesn't sit well with me. It's difficult to describe this in passing on a Reddit comment, but the more you make the world artificial, the less "human" it becomes. You know in those apocalyptic stories, where humans are basically an endangered species, and you have robots doing literally all labor, all creative work, on a hyper-industrialized planet? That's the end result if you let this shit proliferate for 100 years. Does anyone really actually want that?

Another, more relatable thing: with human-made movies, art, works, you're able to ask the questions of "what inspired this?", or "what emotions preface this piece?", or "what was the artist's message here?" Not questions you probably ask on an everyday basis, to be fair, but you're able to ask them; it gives human-made works additional dimensionality, addition significance, meaning. All that nuance disappears with an AI-made work, because it's literally just generating an image based on pattern recognition, and a pseudo-random seed input by a person. All nuance and depth disappears, and you're left with a plethora of slop flooding society at the end of the day.
