While initially a perpetual right to copying for some publishers, copyright was made into what it is today to "promote creation". Funnily enough it's used in the exactly opposite way. Culture is basically frozen, same movie and same music released every week.

The fields where creativity flows the most seem to me the ones furthest away from copyright. FOSS and memes come to mind.

What matters is who made something, regardless of who copied it. I think that in a ocean of AI generated content, this will become more and more important. Platforms like patreon and kofi show that people care about creators and are willing to support without 'buying a copy'
