If you want a short answers it is a text editor. If you want the long answer i might not be the best person for it but here it goes: You start using it as a text editor but it is a bottomless pit of freedom and practicality, where you put 100s of keyboard shortcuts into muscles memory, and one day you will find your self replacing your terminal with emacs. Then you forgot that GUIs exist all together. You will feel an urge to make fun of vim users. Somewhere along the way you’ll start waching videos of Stallman, and form a desire to overthrow the proprietary overlords. Turn back now! ;)

No offense, but it is very misleading. I’m not necessarily disagree what you are saying, but my first impression was that it is based on data, and you know, not just your opinion.

I’m genuinely curious, where are theses numbers from? Could you please cite the source of your graphs?
