How many people don’t know tmux in the industry is really beyond me.

What's the elevator pitch if I already know Screen and I can just open multiple windows of the terminal emulator?

No pitch - just use screen, most people use tmux in exactly the same way - open a few splits and switch between them with keyboard shortcuts.

Tmux is better supported by other tools, such as fzf.

I switched from screen to tmux due to rumor about the screen code base. Maybe not a good reason. But I don’t regret it, tmux works well.

Just an honest opinion of someone who didn’t have skin in the game. Not sure if it helps.

The people GP are talking about don't know about GNU screen either.

With all the buzz about orchestrating in the age of CLI agents there doesn't seem to be much talk about vim + tmux with send-keys (a blessing). You can run as many windows and panes doing so many different things across multiple projects.

The way I see it using tmux to orchestrate multiple agents is an intermediate step until we get a UI that can be a product offering. Assuming we get orchestration to the level it has been touted, there is a world where tmux is unnecessary for the user. You would just type something to one panel in which the "overlord" agent is running (the "mayor" if we talking gas town lingo) and that agent will handle all the rest. I doubt jumping between panes is going to stick around as the product offering evolves.

same, although I'm using zellij instead of tmux. Copilot works well in vim too.
