Copyright gives the copyright holder exclusive rights to modify the work, to use the work for commercial purposes, and attribution rights.

Copyright remains a system of abuse that empowers large companies to restrict artistic development than it does encourage artists. Besides which, you're failing to consider transformative work.

As it is, companies like Disney, Time Warner and Sony have so much control over IP that artists can't make significant profit without being controlled by those companies, and then only a few don't get screwed over.

There are a lot of valid criticisms about AI, but the notion that training them on work gated by IP law is not one of them... Unless you mean to also say that human beings cannot experience the work either.
