I've been a developer for 20 years, I do some reverse engineering stuff on the side using assembly.

There hasn't been a single time in 20 years that it was actually relevant for real work in any way.

Unless you are doing very specific work knowing assembly is about as useful as knowing COBOL (which is also useful for a very specific kind of work that most devs will never do)

Learning new and weird things builds brain elasticity and vocabulary for you to express new ideas. I always recommend people to learn FORTH, or Lisp, or APL. Learn to think with different paradigms.

As an extracurricular activity sure, but if your resume just has FORTH on it recruiters are going to throw it in the garbage because there's no evidence you can work in a modern development environment
