Super interesting. One point about living standards: at this point the world is in the Malthusian equilibrium, so living standards are rather decoupled from technology. (Whenever technology raises your living standards, you have more children, and average GDP per head returns to subsistence level.)
Malthus has had a big comeback in the theory of economic growth over the past couple of decades.
