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.
A lot of the more technical art generators seem to have a lot fewer fixed parameters. The failure to put in the effort to learn about them and make those choices is what I’d argue makes most AI art inherently worthless.
