Something that isn't called out but is playing a role as well is the rise of humanities and interdisciplinary research in India. 20-30 years ago, specializing in ancient languages and texts from a CompLing perspective or a humanities perspective just didn't occur.

As India grew richer, the newer generation of liberal arts colleges (eg. Ashoka) and humanities programs in public universities (eg. IIT Delhi, IIT Kanpur, IIT Hyderabad, JNU) started attracting and hiring Western educated faculty and researchers (Indian as well as Foreigners) to help revitalize interest in humanities and social sciences.

India also now has a new generation philanthropists who are starting to donate to this kind of research (eg. Murthy and the "Murty Classical Library of India" at Harvard).

There is a similar revitalization for older texts in Tamizh, Telugu, Koshur, Pahari, Tibetan, etc as well.

Taleb says that some languages are only meant for ritual.

IMHO, Sanskrit quotes sound cool to those who know Prakrit languages just like Latin and Greek quotations sound cool to those who know Romance languages (and even to those who know English, like myself).

Yes, there is a revival, and an interest. But Sanskrit has always been known to the "priestly" class even though they never conversed in it. This new revival is not going to lead to actual communication, just a lot of visual art based on the script and quotations. IMHO.

It is caused by the ability of LLM to translate it quite accurately
