"With trillions of digital workers and robots entering the economy, a tenfold increase in GDP represents a very conservative estimate of how much full automation could increase economic output. If this modest increase were reflected proportionally in US tax revenues, we could resolve all current Social Security funding shortfalls, lower the retirement age to 18, and increase the average payout to over $150,000 per adult per year." From what money is that "ten-fold increase in revenue" coming from if no one is working? Is this a chicken/egg problem in the beginning in order to ramp this economy up? But even it it can get ramped up, the described scenario feels like a zero-sum game no? Like we're all just playing a continuous poker game with the same players and all the same money.
