Isn’t it because older tools never go away ?

Newer tools only come as alternatives to faster tools that continue to be usable at any time.

For instance I choose to use VSCode and consciously weight it down with plugins and extra linters, because the trade-off is fine for me.

But I know vim is only a click away, and if I wanted sheer speed I’d do it there. And I actually do use it on a day to day basis, it’s just not my primary editor.
