alt Hacker NewsOkay but TUIs don't matter here though right? You can easily run GUIs over the web with any box anyway if you wanted to. So how is your headless sever running 24x7 (which is what allows feature you talk about, not tmux or tuis) not the reason you can do that but TUIs are?
I have a windows box that never shuts down and i remote into it and use it GUI mode to do everything you said but with a proper GUI interface. I also use the terminal but your feature (constantly up + resume + multi device) does not need TUIs to even work.
A server needs a lot more things to have a GUI compared to what's necessary to just run an SSH daemon that offers CLI/TUI access, where SSH is just providing secure network access for the most basic interface the server has anyway (the TTY).
