This ignores the reality of improving technology moving food production to hydroponics and vat-grown meat.That will be restricted, at best, to very rich nations, and then mostly only to the wealthy, not to the countries which are overpopulating right now. Also, a laboratory simply cannot reproduce the exact same sort of nutrients found in high-quality meats. Things like physical exercise which differentiate the meat of healthier animals from more intensively-farmed/factory-raised animals cannot be replicated for obvious reasons.
The increasing exponential rate of technological change will bring new technologies to developing countries many times faster than in the past. Sure, there's going to be a window of time between now and then, but probably 20 years at most, and perhaps as little as 10-12 years.Hhmm, you are clearly a fan of the Singularity, aka "The Rapture of the Nerds". I am more convinced by Huebner who pointed out how technological advancement has slowed considerably at a constantly dropping rate. Even Bruce Sterling, one of the 3 main SF authors who promoted the "Technological Singularity" in his writings, has stated that it was all a highly unrealistic futurian concept, and that it was far more likely that we would have a future dominated by, say, Islam, instead. I note how many current technologies have been promoted as being just around the corner ever since the 1980s or before, such as the advent of sentient artificial intelligence, landings on Mars, or nuclear fusion reactors etc. These technologies are always stated as being about to happen "in 20-30 years time" at any particular point, but never actually do.
Moore's Law has been going on for at least 65 years or so. It shows no signs of stopping or even significantly slowing, due to new advances with graphene, stanene, Weyl computing, etc..People are predicting the end of Moore's law and have already shown evidence that it has been slowing down:-
