It's hard to find the kind of person who likes both, but the ultimate CLI enabler is AI. Ironically, since the rise of actually useful agents I've been using less web and GUI stuff and more CLI. git, ssh, vim, tmux, psql, sqlite3, codex, claude. What more can I ask for? The "there's a unix pipeline for that" mentality that was technically true but ultimately impractical 5 years ago now works phenomenally well. I wouldn't go as far as removing the gui entirely from my machine, but I'm literally down to the modern web browser as the final holdout.
I agree that UX in the LLM age has been woefully under explored. I feel like whole new paradigms are waiting to be explored, but right now everyone is just trying to shoehorn AI into a corner of existing UIs.
