And if they liked optimizing transport, but now the box is self-driving and the logistics are planned by machine? The farm is automated and humans get in the way. The vet is a robot. Also any other suggestion you have is automated - AI is now better at everything. Nobody needs or wants anything the human can do. AI is a more fun friend, a better singer, a more engaging teacher or entertainer, a better movie creator, a better cook, etc. All that's left is Postel's "Amusing Ourselves to Death", from cradle to grave nothing the human does matters or can matter. Then what?

Perfomatively going through the hollowed-out motions of human life like a toddler playing with a plastic kitchen, wishing the ghosts of meaning and fulfillment would come back into them? Enjoy!
