The point is what would you do after learning or may be spending real good amount of time with it, what is the real need.
I learnt sanskrit for more than 6 years and have passed upto threeeteeya(an exam to test your sanskrit skill).
When i learn something i should be able to converse about it with many people as i can and help spread the knowledge or information. But learning an old language like sanskrit.
What i found after learning the language is there is a lot of history which doesn't fetch any real world gain to my career, my social life, my finances or even recognition from a worldwide community.
