You think tools that stagnate will continue to see the same levels of adoption in new generations of programmers? It's an empirical question, I guess I just don't see it, and I say that as someone who loves vim & emacs.
EDIT: I'd bet the unix shell experience is similar. It's hit a pretty stable point where it's unlikely to be revolutionized. There are certain improvements--tools like atuin[2] are nice--but fundamentally the UX will remain the same: you type text commands into a prompt, the basic readline controls work, you may have tab-complete. Text editing has hit this same stable point. You're not going to do better than vim or emacs.
EDIT2: Actually, I think GitHub is a good example of this kind of good stagnation. The code review experience of GitHub's competitors is largely the same as GitHub's.
