We're up to 8.3 billion people now, fam.
6 trillion / 8.3 billion = ~750
And that number has to be spread over 5 years since the target date to raise the 6 trillion is 2031.
750 / 5 = 150
But, like I said, that's still just a conservative estimate that doesn't account for the fact that the AI firms have astronomical operating costs to cover.
