It's almost as if AI/technology is reaching a phase where it can reap every advantage, causing a sort of heat death analogous to the heat death in thermodynamics, where trade will eventually cease because no one has any meaningful contribution since AI can do it better.
Maybe this will create a system where no one has to do any work and UBI will take care of everyone, but humans need a purpose and what happens to society when there is mass depression due to a widespread lack of purpose?
