We aren’t even mining asteroids near Earth’s orbit. Space colonization is a ketamine dream. There’s no extraterrestrial economy. Earth is all we have. One pie.
A pie that includes sand which is now turned into GPUs that can solve complex problems described in English. Value that was unlocked fairly recently from “one pie”.
Of course: Everything is resource-constrained. That’s why it’s called economics.
The question was whether the “pie”—total economic output—has a meaningful upper bound on growth because we only have a whole planet full of resources to exploit as our minds and capabilities allow.
