Again, what HN reader (or otherwise), do you think is interested in reading ancient literature written in Sanskrit? A researcher or linguist I'm guessing. And maybe 3 other people.
I'm afraid your arguments in favour of learning Sanskrit are as generic and theoretical as most other comments.
I am interested. Not a researcher, not a linguist. Just some asshole who wants to know a new skill that may come in handy when exploring Indian mythology. You really need to just concede that your interests are your own and that your rather harsh view of Sanskrit is one that isn't universally shared.
