Ok yes very good point you're right. What often happened in the olden times was that science took the shape of art, or religious or ideological conviction drove tireless creation.

Let's say science is left to the robots and the lack of "laundry" never leads to people's suffering, never leads to people asking the big questions about life, etc (I was making big assumptions about AI-keeps-us-as-pets, life in abundance, lack of common threats or conflicts etc). What art is there to create, sans banana stuck to the wall? Somebody in the thread joked about being fed through a tube in a pod or something

But yeah in such a case there will probably still be some fire art about the alienation implied by merely being a human. In the end, no AI can experience being a human that was replaced by AI. Given the vestigial remains of our by then atrophied intelligence can appreciate it
