The current pressures global populations face due to water access and increased insulation in the atmosphere are not ones that can be magically waved away by technology in short order as population increases and increases the scale of those issues.
Of course there are other challenges, but those two suffice for now.
Riiiiight.
Go modern nuclear.
Nearly unlimited water access only requires cheaper energy (desalination and condensers).
I kid, but a lot of the top Nazis were geniuses by IQ; I don't know that there's any reason to believe that virtue and genius are correlated, which is only one of the reasons I think this whole conversation is a bit goofy. It honestly feels like yet another weirdo billionaire rationalization for why the line must always go up.
Those arguments are addressed in the second paragraph:
> Historically, as we run out of a resource (whale oil, elephant tusks, seabird guano), we transition to a new technology based on a more abundant resource—and there are basically no major examples of catastrophic resource shortages in the industrial age. The carrying capacity of the planet is not fixed, but a function of technology; and side effects such as pollution or climate change are just more problems to be solved. As long as we can keep coming up with new ideas, growth can continue.
