Celebrities like Julianne Moore, Thom York and Kevin Bacon signed a letter protesting the use of unlicensed content to train AI.

"The unlicensed use of creative works for training generative AI is a major, unjust threat to the livelihoods of the people behind those works and must not be permitted," the group says

Thousands of creatives, including famous actors like Kevin Bacon and Kate McKinnon, along with other actors, authors, and musicians, have signed a statement warning that the unpermitted use of copyrighted materials to train AI models threatens the people who made those creative works.
