learning rust might teach a javascript programmer a lot about performance that they can apply to their javascript. learning f# or rust might get a c programmer comfortable with ADTs which one can leverage in C with a little work. i do agree though that taking this too far can just be a waste of time. maybe pick up ONE new language outside of whatever domain you are currently in, see if you learn anything useful.
