What this 2075 top economies chart could tell us about future world order?

How can you have a discussion on future productivity without talking about AI?

All the countries that move up in 2050 and 2075 according to their prediction due so due to superior populations and demographics. 

The US and maybe China are the world leaders around AI right now which will for sure be more economically mere population size.

I see two scenarios for 2050-2075, either the governance around that technology is done properly and we get closer if not have reached post-scarcity through which the very concept of GDP doesn't really make sense or we end up in a 1984 scenario with AI superpowers waging some sort of cold war against each other. 

India, Indonesia, and Nigeria don't really have a tech sector that would challenge that so I don't see why their superior population numbers would help them much in outcompeting the US and China.
