Many things in the world of software are neither webapps nor contain a lot of highly optimized hand-written assembly. That's the worst false dichotomy I've read so far today, and I read political Twitter.
Just because your use case is different from those who have C or C++ code and a good optimizing compiler doesn't mean you need to disparage every other type of developer on the planet.
There are a lot of people who write native ARM for phones and tablets for performance purposes, too. Some of them get down into ARM assembly. If they port to Intel and want to do assembly-level things there, they need to learn twice as much assembly coming the other direction.
