Setting aside the usual arguments on the anti- and pro-AI art debate and the nature of creativity itself, perhaps the negative reaction that the Redditor encountered is part of a sea change in opinion among many people that think corporate AI platforms are exploitive and extractive in nature because their datasets rely on copyrighted material without the original artists’ permission. And that’s without getting into AI’s negative drag on the environment.
I don’t really think you’re expressing much of yourself with an AI, especially creativity. I mean all the power to you if you think so, but you can’t really claim to be anything more than a slightly less cumbersome Google image search bot.
Basically you give “search terms” and then use your judgement to pick and choose. There’s very little expression and a whole lot curating of someone else’s work. I guess if you think making music playlist is an expression of creativity, sure it’ll qualify. But that’s some shallow expression of a personality when it comes to art. Might want to phrase that differently.
