It slows it down by causing developers to fear using the most efficient, productive tools because it will anger the irrational mob who down votes anything they disagree with, rather than whether or not it's adding to a discussion.
If some creation is clearly a copy/paste of someone else's work with only superficial changes then that is it's own problem that can be dealt with in the same way that it would if some person had copied someone else's work, and made superficial changes to claim it as their own. Art created using AI is not necessarily a copy of something existing, and it takes a skilled prompt writer to create their intention. People angry that a different skillset than is traditionally necessary to create art are being awnry gatekeepers in the same way that artists were at the advent of computer assisted drawing or computer generated imagery. New technology, same type of crybabies gatekeeping art creation.
I recognize that it's not a ban, it's just an unnecessary requirement in the current implementation. If it's going to be done, at the very least categorize it so AI code generation is separated from the AI art generation, or other generative tools. I still assert that none of it should be necessary, and if it in some way lowers the quality of the creation then it will be readily apparent and can be judged based on the quality, not the method of creation itself.
