Yeah I bought his book.

Had to stop reading this sad Malthusian look at possible futures, it was giving me literal nightmares.
The demographic stuff, at face value, guarantees massive famines in many parts of the world in the decade or so. This is accelerated if, as seemed likely in the last days of Trump, US withdrawal from "international police" duties increased.
There's a fairly obvious hole in his thesis, he predicted off the bat the US would fold and hand over Ukraine in the next decade, and when the book went to press the Russians were being kicked out of Kyiv: he had the good grace to point out (in a very late edit) this was a fly in his ointment, but it certainly doesn't negate a lot of his points.
The possibilities of autonomous transport and robot workers don't seem to be hugely explored (not sure, stopped reading) but once again they don't really impact his timeframe.
China is the most vulnerable economy in the world to international supply disruption (the US and then Russia are the two most robust and well balanced, but Russia has enormous demographic challenges) and their demographic nightmare is already rolling: they have been lying about the population figures (among other things) for banking reasons and it looks like they will be less and less able to pay for anything.
Any scenario where the US reduces its oceanic trade peacekeeping dollar is a world where everything becomes more expensive, and the more times a resource or item crosses the oceans the more is spirals up. The money to pay for retooling is depleted by some dodgy banking collapses and in ten to twenty years most populations will be to old to work their way out of it.
It seems plausible that there's not many futures without mass starvation in many places (and especially China) in the next 30 years.
Very depressing reading.
