The issue isn’t that people are using others works for ‘derivative’ content.
The issue is that, for a person to ‘derive’ comedy from Sarah Silverman the ‘analogue’ way, you have to get her works legally, be that streaming her comedy specials, or watching movies/shows she’s written for.
With chat GPT and other AI, its been ‘trained’ on her work (and, presumably as many other’s works as possible) once, and now there’s no ‘views’, or even sources given, to those properties.
And like a lot of digital work, its reach and speed is unprecedented. Like, previously, yeah, of course you could still ‘derive’ from people’s works indirectly, like from a friend that watched it and recounted the ‘good bits’, or through general ‘cultural osmosis’. But that was still limited by the speed of humans, and of culture. With AI, it can happen a functionally infinite number of times, nearly instantly.
Is all that to say Silverman is 100% right here? Probably not. But I do think that, the legality of ChatGPT, and other AI that can ‘copy’ artist’s work, is worth questioning. But its a sticky enough issue that I’m genuinely not sure what the best route is. Certainly, I think current AI writing and image generation ought to be ineligible for commercial use until the issue has at least been addressed.
