What are you doing in a terminal that you need real-time collaboration? Here's what I do in my terminal:

* log in to AWS * push commits (though that's mostly in Emacs now) * tail logs from remote services * use ssh * random grepping/cat/awk/sed one-off stuff

I don't see any of those benefiting from real-time collaboration. The use-cases presented on the landing page don't make sense to me either - when my entire team is debugging production, we usually fan out and all look at different things rather than needing to fan-in and all do/look at the same thing. And if I want to chat I'll have Slack open next to the terminal.

How’d you learn how to do all those things?

This is where the real-time collaboration comes in. Easy to teach novices how to use powerful shell commands to make things easy.

What? You'll suddenly need 5 people to chat about that multiline command you're about to type?

What if you open an editor inside this terminal and collaborate in there?
