> ... I encourage people to live in the terminal.

I've done this for decades. screen or tmux (although I still confuse the keybindings between the two).

When coding on the move (mostly when I had a long commute or was away from the office visit clients) I'd use the Linux console (Ctrl+Alt+F1-F6) rather than X.

Even in the office I had an old amber/green terminal that connected to my Linux desktop via a serial port.

Nowadays I have a 14" USB-C monitor (ASUS Zenscreen) that sits beneath my main monitors which runs a terminal full screen.
