practical reasons for learning assembly

I've been learning MIPS assembly and I'm wondering if there's any practical uses for it. Is there a lot of demand for people who write assembly these days? I've seen some job postings online looking for people to help write/debug embedded systems, but it doesn't seem like it's a very profitable skill to have compared to more high level stuff.

There's not much practical use outside embedded, operating systems and extreme optimizing (videogames, scientific computing). However it can still be helpful when debugging, and just knowing how computers actually work makes you a better programmer.
