alt Hacker News> I think yes, because git famously has a terrible UI, and any amount of telemetry would quickly tell you people fumble around a lot at first.
1. git doesn’t have a UI, it’s a program run in a terminal environment. the terminal is the interface for the user.
2. git has a specific design that was intended to solve a specific problem in a specific way. mostly for linux kernel development. so, the UX might seem terrible to you — but remember that it wasn’t built for you, nor was it designed for people in their first ever coding boot camp. that was never git’s purpose.
3. the fact that every other tool was designed so poorly that everyone (eventually, mostly) jumped on git as a new standard is an expression of the importance of designing systems well.

UI means "user interface". For a CLI tool the UI is the commands and modifiers it offers on the terminal.
Mercurial was better than Git on almost any metric, it eludes me why it lost out to Git, perhaps because it lacked the kernel hacker aura, but also because it did not have a popular repository website with cute mascot going for it. Either way, tech history is full of examples of better designs not winning minds, due to cost, market timing, etc. And now with LLMs being trained on whatever was popular three years ago, we may be stuck with it forever.
"UI" is a category that contains GUI as well as other UIs like TUIs and CLIs. "UX" encompasses a lot of design work that can be distilled into the UI, or into app design, or into documentation, or somewhere else.
