The Importance of India

But with knowledge driven economy coming into picture, Having a huge population has any advantage?

First world countries certainly have head start in this case, who are already attracting best brains from across world ( universities and companies)

So, India will retain the importance only if it can sustain current brain drain which means huge investment in younger generation.

As somewhat of an metric, I'll let you look up the smallest semiconductor node India can produce natively.

How you organize your society matters much more, Japan/SK has fraction of the global population, and somehow maintain their economic importance.

India has all the problems of a democracy without much of the benefit. It's more likely that India becomes a CCP style country than stays a democracy.

If India was so great it's smaller immediate neighbor wouldn't be so hostile towards it, and friendly to CCP.

CCP was able to organize G77, so they have the numbers on their side, it's just that poor people don't have a voice, China is providing hard power to the masses of humanity against the interests of G7.

It's a major shift in world power, whether G7 likes it or not.

I am no fan of CCP, nor is CCP a fan of how they do things ! but its the world we live in, where the state department can just overthrow the govt of a major country if it likes, you need the use of hard power to survive.
