I've been trying to migrate back to command-line-only applications to get a facsimile of this.

I don't think that command-line tools are better in any kind of "objective" sense, but I find that if you live primarily within tmux + neovim (and maybe Codex/Claude if you want to be super cool), then it's much easier to not be distracted by the rest of the world.

Nowadays, when I do work I will have a full screen terminal window open. I have an utterly gigantic 85" 8K TV as my "monitor" and I will have an ungodly number of tmux splits, but importantly I don't think those splits are distracting from actually doing work. At some point I will figure out how to get the dbt Cloud `preview` functionality working locally and I think I can avoid the vast majority of any of my work requiring a browser.

Sometimes it does kind of feel like I'm just being a hipster by using a lot of tools that have existed since antiquity, but I think they do a good job at not being distracting.
