@pluralistic which I think adds yet another reason I support your view that we should treat the question of AI training as a labour rights discussion rather than a copyright discussion.
It's not at all clear to me that training AI is a copyrightable activity anymore than training humans is - or should be.
But labour doesn't have that question at all. Labour is first and foremost about human needs.
And making art is definitely a human need.
Making art is what made us who we are as a species.
Most human endeavours we do to survive. But not art: we don't make art to survive, we survive to make art.
if we no longer make art, will we really exist at all ?
