You are free to judge people for liking AI music, or in fact anything obviously. We all judge, and must live with judgement. But is this judgement supposed to be of any particular importance given it is equally likely someone is passing judgment on you for something they may personally dislike?

It just often feels as if there is an assumption that one's own standards are that which is "normal," while everyone else's are the weird ones. But to plenty of other people, our own interests, values, hobbies, or lifestyle choices would may be considered equally rubbish and worthy of judgement, according to their worldview and experience.

I would say, judge people if you want. As we all largely do, though I try not to do. Provided it comes with the realisation you're not somehow standing outside the exact same process.

Note: I do not willingly consume AI content, nor do I have any particular interest in doing so. But I have had people very openly judge me for things that for many of us here would be considered entirely normal, including my choice to work with computers for a living. So I do not have a tendency to give any particular weight to the "judgement" of others, silent or otherwise, where my choices do not materially impact that individual or society at large.

To lighten the mood a little more, I am quite openly judged (and silently I expect) because I have a particular enjoyment for Russian hardbass :) Which many if exposed to it I would expect consider it to be total garbage. But it does nothing to reduce my enjoyment of it and nor would I allow it too.
