> We expect real-time collaboration to dominate future markets as the pandemic runs its course and forces people and businesses online en masse
I'd think that the area for the easiest investment in this problem space wouldn't be on the creation of a new terminal emulator (like iTerm2 or the Windows Terminal), but instead as a piece of software running on the remote server, something like tmux. Imagine instead a tmux that could allow multiple users to connect to it simultaneously, and drive different panes at the same time, or view the commands that another user is using in a given pane.
Then, regardless of what terminal emulator you choose, you'd be able to collaborate with your teammates, once you connect to the same server session.
When I think about a "Terminal 2.0", I imagine something more like [this](https://github.com/microsoft/terminal/issues/3121). Ideally though, whatever protocol for rich feedback and content embedding wouldn't be tightly coupled between the shell and the Terminal, which I don't believe is something that [UpTerm](https://github.com/railsware/upterm) did well (though correct me if I'm wrong.)
