That will not happen. All 3 will exist as big economic super powers from 2035 to 2060. India will not be a military super power for next 25 years. We just don’t have the inclination towards that. Current government is the best one we ever got and it’s complete focus is on development and economy. Unfortunately MIC can’t be developed overnight and I don’t see any changes in our strategy in foreseeable future.
The biggest strength of US is it’s ability to attract the best talents from all over the world. As long as they maintain that it will remain a super power. Also US will never be alone. No matter how much Europeans hate US, they will still stick together. After all white supremacy does matter.
You are looking at the current situation and extrapolating that to the future as well. The future is not going to be anything like that. Considering a 2050+ timeline, the greatest threat to the world is not climate change, but population decline. India is going to add 300 million people over the next 20 years. So all the brains are here. Now, if 100k a year decide to immigrate to the US, that's fine, but they are unlikely to be the cream of the crop because wealth and lifestyle would have changed enough to duplicate Western standards of living in Indian cities by then. So most of those 300 million will stay in India.
Otoh, China is going down the drain already, they are going to lose 300 million people by 2050 and they are way too averse to immigration to make up for it. Even if they want to make up for it, they can't just bring in 300 milion foreigners, their govt system will collapse. Whereas the West is busy changing their social fabric via both immigration and wokeness. Yeah, the US is set to have 400 million people by 2050, but that doesn't compare very well with India's 1.7 billion people, alongside another 2 billion people we will have significant market control over, Africa and ASEAN.
Furthermore, for the first time in human history, energy will be produced in a factory on a large scale, and it will become the prime mover of the world. And India will be the largest producer and supplier of this energy. So global energy markets will largely be controlled by India. The West with its exhorbitant costs and the Chinese with a declining population won't be able to compete. Plus fuel will be dirt cheap in India, like it is in the ME today.
India's $20T economy in 2040 won't be the same as America's $30T economy. And India's $40T economy in 2050 won't be the same as America's $40T economy. Labour costs in the US and China will be insanely high, a large chunk of the population will ghettoise and will sit around jobless while India transitions into an advanced economy. The thing is the EU, Japan and SoKo with their declining populations are yet to experience competition. Once competition pops up, they will disappear.
Considering India's rising population, major energy producer status and control over other large markets, it's very, very likely that large companies will shift base to India. The choice will be simple, either move to the main market with surplus labour or get killed by the "protected" competition coming out of India. You think India can't do its own CHIPS Act in pretty much every sector?
China’s bigggest issue is they do everything in excess. Whether it’s population control, infrastructure development or pseudo colonization by BRI. They should have moderated the pace at some point. Now they are riding a tiger. Let’s see how it ends.
The West is committing to the same excess when it comes to immigration.
The number of murders in the US is the same as that of India, and this is with India having 4 times the population that's also very poor. And it's rising in the US whereas it's falling in India. That's not a good situation to be in. The US is definitely no longer a place to raise kids in. So its ability to absorb cream of the crop migrants is lower than its ability to absorb all the ghetto zombies that are bringing in more drugs and crime.
To make matters worse, feminism has ensured that at least 50% of the women in the US will be childless by 2030 and they are yet to consider this in their population metrics. Recall that ridiculous advice Biden gave to that girl, telling her to have kids only after 30? Yeah, that's a recipe for disaster. And we already know that most children in the US are now growing up without fathers, so that's already a deadend for these children.
A major advantage India has is we are culturally homogenous, or at least we are more tolerant of different cultures. And our population is so big that regular amounts of immigration will not affect us as much as it does in the US. Yeah, we have immigration from BD, but they are culturally similar to us, unlike Muslims from the ME or Africa.
Betting on India's future is like betting on the winning horse. We are going back to the past, where we controlled significant chunks of the global market. China had the potential to be in a close second place, but they screwed up royally. And America simply lacks the population. Both are practically guaranteed to go into a decline and this will become visible by 2030 or so.
On even larger timescales, like 50 or 100 years, India will retain the advantage.
