I don't know how he got the numbers either. He's talking about Poland (lol) of all countries becoming a world power. Last I checked every country he talked about being a future world power have low average IQs, low number of multinational companies, low scientific publication rates and low patent numbers. I think he's talking opposite.
Please read the history to understand that some of the countries you call "low iq" were great powers. Learn a little bit about the Russian and the Ottoman empires which ruled large parts of the world.
And read about their current growth figures, and human and other natural resources.
Prior major inflection points like the fall of the British, Soviet and Ottoman empires and the rise of America were not seen by most people. Turkey's economy and political clout in the region have been on the rise in recent years. And they are strategically located successors to a great empire.
