The problem is more that generative AI is trained on the actual work done by other, actual people. And we have no legal framework so far how those people should get paid in turn.
Plus, let’s not for a moment imagine that Sweeney is saying this out of a firmly held personal belief. He’s entirely based on his reactionary stance to Steam. Steam goes against generative AI -> Sweeney is in favor of it. If Steam would say they’re against eating live babies, you can sure as hell bet he’d sing praises for that, too.
