The whole point of a TUI is that it can operate under no-GUI constraints.
I can SSH to any server and use a TUI because SSH can handle that. Running an entire GUI and setting up VNC/RDP would be horrendous by comparison.
Alternatively, a TUI can be a part of an interactive CLI command where it maintains context to your CLI session. For example, I have a tool that helps wrangle AWS accounts and regions where the CLI momentarily drops into a TUI to help pick between regions and accounts if not already specified in environment variables. If I had to type all that out every time it would be very annoying. Hitting some arrow keys or searching with a few letters beats the CLI experience, and a GUI experience is not possible.
No. I'm a cofounder at Fly.io and have spent the last 6 years (really, the last 25) in ops world. The points you're making here are addressed directly in the article. It's kind of hard to miss them!
