Earlier quoted context omitted.
In what way is training "copying"? This is just an attempt at a landgrab by idiot copyright maximalists.
Name-calling doesn't help your argument. But I do suspect that there are two overlapping schools among the most vocal supporters of this technology. - Those who think that generative AI is so wonderful because they have a vested interest and/or have bought into the most breathless hype - Those who more or less think copyright shouldn't exist in any case
I still believe a little bit in Jefferson's vision. It's just that that has so little to do with copyright that we're probably not even talking about the same thing. He envisioned copyright as being an incentive to create and do new things, to learn new things.
And here, as it would be used, it would shut down new technologies and quash new ideas. Clearly, such people are doing copyright wrong. I am not religious, I do not believe in "sin", but if that word did have any real use, it might be strong enough to describe those who would misuse copyright.
In any event, Jefferson was granting a very limited privilege and not describing a fundamental human right. This privilege was granted by the people, and the people do have the right to revoke that privilege if it continues to be misused. This, I think, is all the warning the misusers deserve. A comment that will be read by hardly anyone, that they will surely never see, and which will give them no headsup at all.
