alt Hacker NewsI've always been a bit mystified by the popularity of TUIs. To me, the power of the terminal is the streaming model. Composible utilities is something that is much less common in GUIs.
I get it that maybe the constraints of terminals force design of TUIs to be more focused on the purpose of the tool than polish, but it's not that compelling of a point to me.

The command line shell has that benefit of piping text between programs. TUIs are runnable from the command line shell. -- So you can get many of the benefits of a GUI (e.g. discoverability) while sticking close to the terminal where you're doing things.
If you're going to "run command, edit command, run command", performing the edits from the terminal you're running the commands in seems reasonable/intuitive. (In contrast, for tools like VSCode, I think it's more common for terminals to take up a fraction of the screen space rather than switching it to full screen. And then developers will say they need a huge monitor).
It also seems to be that keyboard-driven programs are more commonly TUI than GUI. e.g. magit or lazygit. Or lazydocker. Or k9s.
I like them because they’re easy to run in a container / sandbox.
They are very useful when working on remote servers, VMs and containers. Much much more convenient and robust than, say, X forwarding.
For some basic stuff like vim it works fine. But for almost everything else I'd rather a regular CLI tool or a web interface. I suspect a lot of the popularity comes from people who want to feel like a hacker using 10 terminal windows, but actually want a GUI like experience.
