> For example: Let’s train a network on Beatles music to generate new Beatles songs. I’m pretty sure music lawyers will find a way to prove that the trained network is violating the label’s copyright, as they always manage to do that.
The people making the machine that learned (and recites) beatles songs aren't infringing though (most likely). It's those that use the machine to create and distribute the new works that are.
Same here. No one will be able to say that Copilot itself is a "derived work" or somehow uses the code in a way similar to a computer program (Although such claims have already been made - I highly doubt that's the case). But those that produce a whole file full of GPL code verbatim (Which will be rare, but WILL happen), are at risk of violating the license terms if they distribute it under the wrong license.
