That's fascinating to learn. I'm curious, is there a political angle to the revival of some of the languages? The posted article mentions "values and traditions" associated with Sanskrit, and I imagine some religions and cultures are motivated to bring back languages for..not to say "selfish", but for their own survival and spread of ideas.
There is a political aspect to it as well, but it's overstated to a certain extent.
Most of these humanities programs are being created via philanthropy from alumni or business families now thinking about their legacy.
Also, now that India isn't as poor as it was previously, it's unsurprising that a new generation of humanities and social sciences researchers are choosing to take roles in India versus abroad.
