Relative abundance is a concept worth considering. How much food is thrown away vs produced? Housing laying empty per homeless capita? Space needed to power the world with solar power? Trillions of dollars in valuable minerals from one asteroid?

One thing is for sure, the sustain each human's basic survival needs, we have already surpassed the requirements. To sustain a hedonistic treadmill x8 billion, sure, might get dicey. But we are world builders, and I believe the natural path forward includes simulations. Maybe in the short term, maybe in the virtual reality long term.
