Exactly. Atom is a few months of age, Sublime a few years, but Emacs and Vim are both around 30 years old. That's 30 years of work on the core editor, as well as packages and documentation. Plus, they're FOSS meaning thousands of people have worked on them from all over the world.
This makes it really hard for new proprietary editors like Atom or Sublime Text to just come along and be better than these existing monsters. Personally, none of them has what it takes for me but I see reasons to believe they can stand a chance in the near future.
2-3 years in an internal organization does not even REMOTELY compare to 20-30 years in the active open source ecosystem like Vi/Vim and Emacs have had.
