And Atom, as well.

I suppose TextMate was a bit more niche, being OS X only, but at one point it seemed to be everywhere.

Hmm, while we're counting, what about BRIEF? At one point, widely enough used that Visual Studio even had BRIEF emulation!

(When I was starting out in software development, almost all of my colleagues used this. Now just a footnote.)

BRIEF by UnderWare! I loved that editor. I particularly liked the “go to this line number, but use the line number before unsaved edits”. This let you compile a file, get the error log, then start making edits; but the line numbers in the error log were still useful.

VSCode is why Sublime Text, Atom, and others are not as relevant as they once were.

And in 10 years, there will be a comment saying "XYZ is why VSCode is not as relevant as it once was."

And Emacs will still be around.

Atom is not around. Not 100 percent sure that VSCode will be around. (But I also don’t think that this should hold anyone back who finds VSCode to fit their needs best. There’ll be something else that will take its place.)

Just as Sublime Text is still around :-)

My impression is that all of those are fads, we jsut haven't seen VS Code fade way yet, like the others have. I've used Emacs throughout all of those fads, seems easier than switching editors every few years.
