Copyrights do both, they protect all creatives, it’s not one or the other.
> Banning AI music many only protect the same people
How so? AI threatens publishers and copyrights holders the most. Don’t confuse big music with big tech, they’re not the same people. Maybe browse the list of AI lawsuits related to copyrights and note how many publishers there are https://ailawsuittracker.com/copyright/
Breaking the copyright system is very unlikely to leave independent artists unscathed, I believe AI is already doing significant damage to independent artists. Breaking big publishing system won’t help either, given the number of independent artists striving to break out and go big and land a publishing contract.
