If population jumped into the hundreds of billions we would die off for a bunch of different reasons. Current tech doesn’t really exist to sustain a population that large.
I mean obviously if a hundred billion just appeared tomorrow then we would have trouble scaling production, but i don’t think we really lack any of the hard inputs. Switching from open field to greenhouse food production alone increase food production ten times over while reducing water usage, just require a lot more farmers. We are not about to run out of land for housing anytime soon, and have plenty of spicy rocks for fission power.
