One reason for that is that, like with ideas, society benefits, from styles intermixing. So making them "copyrightable" would be to the detriment of society. B

One reason for that is that, like with ideas, society benefits, from styles intermixing. So making them "copyrightable" would be to the detriment of society. But the other reason might be that it has just not been feasible to actually measure things like “style“. And if you cannot, in your lawsuit, put into words what you claim is, and where its boundaries are, it’s impossible to enforce it. It’s very much possible that people will forget the former reason and jump on the latter, now that one might be able to use AI to actually quantify, measure, and map things like style. In fact, I wouldn’t be surprised to see companies like OpenAI play Good Samaritan and “helping legislators“ solve the problems generated by AI. Only after they have secured the own datasets, of course.
