Artificial intelligence is getting a big push right now from various big-tech types, but the technology comes with a lot of obvious ethical concerns — especially when deepfakes are involved. Consider, for instance, this stunt by David Guetta. The French DJ-producer used two separate AI programs to create fake Eminem vocals and was so pleased with the results that he played them at a gig. In the YouTube video where he both shows off and explains this trick, he says he’s “not releasing it commercially obviously,” but it’s already a pretty wild and unsettling scenario, especially if you’re Marshall Mathers.
