> I wonder how do people come to a decision that it's a good idea to start their own text editor when vim and emacs exist.

Vim/Emacs have a huge community and ecosystem, but they aren't exactly perfect. I don't see anything weird about people writing their own editor.

I'd personally love to have a Python-programmable editor a la Emacs, and if I ever write a text editor, it's gonna be like that.
