Once AGI happens, it will have an owner.

That owner should lobby to cut their taxes, destroy all foreign competitors first, then destroy national competitors. It is now worth $200T+. Either your business pays taxes to the AGI to let your business succeed, or is destroyed by AGI allegiant competitors. Either you pay the AGI for validating your citizenship, or cannibalize your fellow worthless derelicts to avoid starvation.

Either that, or we could have UBI/freedom dividends, with taxation of the ultra successful, before AGI rules all, and prefers the Skynet profit and power of genocide to human sustainability.
