Which job are worth doing and which ones you'd rather the AI do? AI should enable things that were previously impossible because of time constraints. If time is money and we were previously trading with money, we will get back to trading time. Manufacturing time for instance. Compute times. For commodities, that might be automated to some extent, I am not sure. The friction in exchanges is where the money is made and the friction here may be at the interface with the real world still.
