Agree with the rest of the comments here: keep making TUIs. Fully keyboard-driven, compact interfaces that live in my terminal with the rest of my CLI devtools are the best!
The only one I use is Copilot (inside of a VM). ALl other applications I use are GUI/CLI/webapps.
- yazi as a file explorer
- lazygit for git
- tmux/zellij as multiplexers
- fzf left and right for a bunch of utils (terminal history, switching between projects in zellij/tmux when working in multi-project workspaces, etc)
- neovim as a text editor
- glow for markdown reading
- currently on pi for my home harness, CC at work
Claude etc do make sense as TUIs too, but I don't like they way they were implemented. They mess with basic terminal features like copy/paste or scroll when there's no reason to. And they're somehow heavier than actual GUIs.
