I'm definitely bias towards frontend/backend web development and apps (I.E. mobile/desktop apps).

But that's not to say the premise is bad - I don't think it's wrong to assume the majority of work is in that area, definitely for young developers. There aren't that many real-time and performance-demanding programming jobs compared to web development.

I don't think even game-programming uses bit operations heavily these days- most of the low-level work is done by third party engines.
