This is some real crazy talk here. The idea that you should limit yourself to the particular set of knowledge you wish to make money off of is insane.
There's almost no such thing as wasted learning, even if you're not interested in pursuing it for a career. Maybe it's a hobby, maybe you touch it in a tangential way for your normal work where a basic understanding brings value but is not necessary.
This is the same attitude that undervalues previous experience and builds in favor of specific lingual or stack competence.

Crazy talk? That's what you get when you blatantly ignore half of what I said. In the previous sentence I quite literally asked if these want to be doing data science to begin with. If they don't have any interest in it, then it doesn't matter whether or not they know how to do it as far as the company is concerned; they're not going to be doing it either way. Nowhere did I ever suggest that it's somehow a good idea for people to be limiting themselves to a particular knowledge set.
