Here’s an interesting video. It starts out with some potentially startling demographic statistics, and then ventures into some fairly familiar Speculist territory.
By the time we get to the end, the “shocking” demographic facts seem to have stopped mattering altogether. About midway through, we see a reminder of how quickly and thoroughly national prestige and influence can change on the world stage. But I don’t think either of the nations mentioned near the beginning of the video will become the new dominant powers. At least not for long. They will almost certainly be eclipsed by something like the rapidly growing “country” which is mentioned later.
And then entities like that will be eclipsed by something else altogether.
