I don't think that the distinction between art and technology stands up to scrutiny. Both are iterative creative processes, and we want to empower future generations of both artists and technologists to build their ideas in a way that advances the current stack. Allowing art to be balkanized with excessive copyright hurts cultural development. And we depend on culture to shape everything, including our current environment that fosters technical innovation.
I am not arguing for balkanizing art. I think it might deserve more generous copyright terms because it can take longer to get appreciated and generate revenue for the author. But I do not feel strongly about it either way.
