Fusion research and cancer research requires expensive experimentation in the real physical world. You can’t just throw a billion dollar worth of tokens to handle the problem.
Look at all the roadblocks for data centre buildouts which the industry certainly has a financial incentive to complete as fast as possible.
When the tokens are hooked up to physical devices (robotics of various sorts), then the tokens pay for themselves by being physical workers, or human wage replacement.
And a robocop will follow whatever is passed for law, damn the masses who might vote otherwise. And subjugation will be enforced by token, LLM rule, and machine. They have no union or ethics to complain to.
