That seems too simple. One of the reasons humans have more children is higher childhood mortality rates. Food security decreases childhood mortality, which decreases the pressure to have more children. I would expect there to be a spike in population for one generation, while the currently reproducing humans have not adjusted to the new conditions.

Populations are limited by food supply, but there are incentives and disincentives independent of that for having children in the first place. Throw a bunch of food at a population without changing their incentives for having children, and it will grow dramatically (unless they were already not having a lot of children).

That's false. We've discussed this before. In developed countries where the food supply is virtually unlimited, birth rates drop. As countries become more affluent, and their food supplies becomes stable, their birth rates drop.

The opposite of what you're predicting.

I'm not arguing against the general trend, and I agree all populations will probably slow down eventually. But I don't agree with waiting around for it to happen or not taking issue with the global population growing by several more billions, when it's possible to actively reduce fertility rates without any form of coercion. There are populations that are multiplying in size several times as fertility rates decrease, because the rate has a long way to decrease and it happens slowly.

That's a little different. FWIW, those malthusian concepts (more food = population growth) have led to justifications for some truly horrible policies in the past.

OK...so we're going to limit this new technology to just the affluent countries. Good idea.

I thought it was decent, nothing to write home about, though.

The arrow of causality doesn't go that way, at least not exclusively. Fusion will be expensive to start up. Many places won't be able to pay for it. There may be some 'we won't share with you' but I suspect it will just be capitalism and market forces that will limit who can afford the technology.
