I’d be fine with copyright going away altogether. People sometimes object to this on the grounds of “But Disney will just steal your ideas and make money off of them”. If their works don’t have copyright though, you can do the same right back to them.
This is also one reason that I appreciate generative AI. Short-term, yes it will help Disney and the like. Slightly longer-term, why would anyone give Disney money if you can generate your own Marvel movie yourself?
The genie also isn’t going back in the bottle. Copyright is a dead man walking. If you dislike what large companies like Disney are doing/going to do with generative AI, push for anyone training a model to be forced to let anyone whose work went into that model for free.
