General scenario:
Tsarist Russia survives to the present. It reforms repeatedly and by 1960 it is a high income economy.
Western Europe does as well as original timeline, only now it avoids the World Wars and is somewhat more populace.
US does as well as OTL
Japan does as well as OTL, but perhaps somewhat better demographically.
The Ottoman Empire survives to the present as an uber rich secular oil state.
China gets taken over by a capable centralized regime in the late 30s, and becomes high income by 1990
Unpartitioned India gets independence around 1950, avoids Socialism, and becomes high income by 2005.
Latin America never jumps the shark, and is almost all high income by the 80s.
Much of Sub-Saharan Africa is either a high income economy or close to it by today.
What kinds of tech might we be looking at in a scenario like this with absolutely poverty largely eliminates by the 1980s even in India and Africa, universal literacy planet wide by the 90s, high levels of economic development everywhere, completely interconnected economies, over a third of the worlds young adult population with college degrees, more gigantic companies spanning the world, and far more overall international government an corporate ventures?
