Sure, and “impossible” meat wouldn’t have existed if people weren’t already eating actual meat

This comparison only holds water if impossible meat were composed of bits of rearranged animal meat... Which it isn't.

If generative AI means less real people get exploited that’s a win in my book.

That's not necessarily a win for everyone. Some people actually like working in the porn industry. Besides that, their likenesses are being stolen and used to produce reproductions and derivative works without consent or compensation.

Also, I think you and your buddies here are missing the plot. Generated porn and generated porn of real people are related but different things. I think that's pretty commonly understood which is why these sites have policies in the first place.
