You don't really know how AI works, do you? A single voice actor couldn't produce enough lines to fully train an AI model even if they spent every second of their life in the recording booth.
So tell me then, which of the billions of input recordings do you pay licensing fees for and how much? I mean sure, we could make a law that forces AI companies to pay for every single piece of training data. Which would probably kill AI training for the entire region where this law applies, severely crippling our already weakened economy. But I guess, at least we're keeping the moral high ground while doing so.
But seriously, the EU is cooking up a pretty amazing Ai law right now. Thought out by people far brighter than you and me and it seems to be pretty amazing at balancing economic interests with ethical obligation. My hopes are high for that one!
