What Happens When AI Runs the Entire Economy?
A deep dive into what it means for algorithms to run prices, markets, and growth in real time. Short scenes on how fragmented automations can close into a single self-optimizing system. Discussion of labor disappearing, options like universal support or enforced work, and the risks of freezing contested values into permanent code. Exploration of power shifts as governments and code controllers vie for economic sovereignty.

What Happens When AI Runs the Entire Economy? (Narration Only)
A tour of what it looks like when algorithms coordinate prices, wages, and resource allocation in real time. Short scenes on markets turning into predictive simulations and the feedback loops that make an economy self-running. Discussion of mass job redundancy, policy power shifting into code, and whether humans can meaningfully stay in control.
