True, silicon valley 70% of scientists and engineers  are foreigners.
And a big chunk are from India.

However unless they willing to go back to help the nation, India will struggle to make name for itself.
An increasing high interest rate and protection will make India job difficult. 
Especially everyone now chasing for same IT pie to  further the growth.

Nevertheless Germany and Japan should be surpassed by end of this decade if nothing change. 
Unless something drastic happen.

I think you are mistaken.

India produces so many talents it is too many for its under developed economy.

That is why they have gone all over the world.
