Because having access to the condensed knowledge of humanity might be more valuable for society then having access to Lars Ulrich's shitty drumming.
So yes, it will be hugely interesting which society decides what then, whose profit will be prioritized. And societies won't easily find good answers.
Under the current copyright regime, nothing's stopping you from condensing that knowledge yourself and publishing in the public domain. But that would be a lot of work for you, wouldn't it? And I suppose you'd rather do work you'd get paid for.
When society decides AI slop will be the only item on the menu, then copyright will die.
I deliberatly formulated that channeling myself as the kid who actually found his drumming valuable but didn't have the money to buy (all) of it. Who was annoyed at society deciding I should not have it.
So I still don't have the answers but the stakes have certainly gotten bigger.
