I don't think that IITs or IISc or institutions are deciding factors. I feel that people who do interesting stuff (not just in software, but in all aspects of life) do it despite their backgrounds, conditions, and other labels. Of course there is poverty, and lack of basic education for millions of people, but there are also millions of people in India, and the rest of the world, who have the skill to do very interesting things.
It reminds me of the collaboration between Hardy and Ramanujan. To me, the significant contributions from around the world, including India, represent Ramanujan working on his own in India while your PhD experience at UC Santa Barbara could be comparable to that of Ramanujan working in collaboration with Hardy at Cambridge. Hope that is not an overstatement. Your work should serve as an inspiration to many in India. Thank you for giving us a language to code in.
I was aware of large-scale project a few years back called FOSSEE (centered at IITB) which was promoting Python and Scilab. I'm not sure if they're still alive or whether they've run out of funds. Prabhu Ramachandran (of the Mayavi fame) was one of the key people behind it. Seems like something they ought to be funding.
Anyway, kudos to Simons foundation for funding Julia's development.
Disclaimer: I work at one of the top institutes you mentioned.
Even as we worked on Julia, we have been snubbed by some who think Julia is not real research, and had a hard time getting papers published. There is a larger issue of how open source foundational software gets developed and incentives for people who do that. Universities incentivize writing papers, not software, unfortunately.
Eventually, it did work out and SIAM Review published our Julia paper.

Poor people are usually still afraid of falling back into poverty plus they still have poor friends or relatives who might rely on them.
The reason is not lack of ability: my guess is that at any time India's best institutions like the IITs or IISc have at least a hundred people who could build something like Julia. Instead it is perhaps India's poverty that prevents people from starting something that does not have an immediate academic or business payoff.
