Exactly my thoughts as well. We're now starting to automate our own culture away: stories, art, music... Why would you spend the years building skills to create something in a sea absolutely flooded by automated algorithms? As these AIs get better, it will be more and more difficult to distinguish the output from human minds.
I keep wondering what the endgame here is. Once everything can be algorithmically created, what's the point of humanity anymore? Just consuming an endless flood of auto-generated, recommendation-optimized content?
