The real reason TUIs are back is not one reason, but a host of reasons.

The biggest current reason is fashion. Tools like Claude Code did it, and while they actually had good reasons to run in the terminal, the tools' popularity and wildly different look, especially to non-terminal-native users became a signal of some positive sort.

I don't believe that any of the rationale posed in the article is a popular reason developers are using.

Fashion is a big driver for sure but TUIs do have advantages over GUIs that are real, especially for powerusers.
