Editing large pieces of text efficiently is a Hard Problem, especially collaboratively without conflicts.

In the case of editors like Xi and XRay, they use CRDTs, which doesn't look anything like how Notepad would represent text.

There's real work here that's actually useful, it's not just "another extensible text editor".

I have never, even once, in my nearly-20-year career had the desire to collaboratively edit a single, specific text file.

Isn't collaboration without conflicts what version control systems are made to do?

I even think it would be annoying if someone would just move cursor around when I edit something. And there definitely would be conflicts if they would try to edit the file at the same time. Who needs this feature?

The way it generally works is that each user has their own cursor.

Google Docs gives everyone their own cursors

Proof by personal experience isn't all that convincing. Maybe you've never done pair programming, but other people have.

If you really need to collaborate on the same file, can't you just share a session in tmux?
