> Now these two people how do they make money? they pay each other so there is no extra value created thus the amount of money as value symbol remains constant.

The money just circulating around is actually more or less how a normal economy works. If you have a two person world where one person makes food and the other makes tools, the money just bounces back and forth between the two people as they trade tools and food. It facilitates trade by acting as an IOU in case the first person doesn't need to trade tools at the exact moment the other needs to trade food.

AI and robotics will one day be able to produce food and tools without human labor. So there could be plenty of wealth created. The question is how do we distribute that wealth when humans aren't needed to make it? We need a new distribution system that isn't based on pay for labor. A lot of people suggest UBI.
