If all of those 10s of millions of jobs are replaced by Ai and robots, who are the customers going to be that keep the economy going? Universal Basic Income (UBI) has already been discredited. The Fed printing all of the money to replace taxes would destroy the US Dollar. I really don't see the economic model that exists after AI and robots eliminate 25% to 50% of the jobs. Somehow I am not able to imagine the same transition happening that we saw during previous technology changes. Is it just me? I am not seeing the future economic system that makes sense. One thing I am sure of, UBI is not going to be it.(Wall Street Mav)
