I find it unlikely to be a duoply of hegemony for long, some countries to watch are Germany, Japan, India, Nigeria, and Brazil. You could broaden the geography to continents were I expect major players to emerge on each.
We are only a few decades since the "end of history" and much has changed. What do things look like beyond 2050?
Brazil is basically the world's soy farm. It's at least half a century behind the times. I still have no idea how it managed to insert itself into the BRICS economic block. The notion that it's on the same level as China, India or Russia is just comical.
All of the small miracles you listed happened in spite of the culture, not because of it. It's also not a coincidence that both are deeply linked to the most successful brazilian enterprise: the brazilian government.
I'm trying to avoid getting too deep in these Brazil tangents so I'm gonna leave it at that. Anyone who cares enough to know what I think about the subject can just look up my comment history.
Timothy Snyder, in On Tyranny, has a chapter about staying in touch with friends from other countries, and while we are not friends, this thread is in that spirit and I have learned things from you, so thank you!
