That's gotta be part of it. But I think another important part is how TUIs have important restrictions that lead to surprisingly delightful applications despite their downsides:
- You don't have control over font size and your color palette can be limited (and chosen by the user in their Terminal settings), so it's hard to go too off-the-rails in aesthetic design
- You work on a strict character grid, so it's hard to get things like padding, margin, and leading wrong.
- You can't assume the use of a mouse, so everything has to work on keyboard shortcuts. This usually leads to extremely power-user-friendly tools. Plus, keyboard-driven, power-user-friendly UIs are hot right now, even on the web (Linear, Fernand, etc.).
Is there any evidence that Rust proponents did it, or are people assuming that because Rene has been critical of Rust? That would be horrible if true, but I'd rather not jump to conclusions that fast.
You're not likely to get any useful response. This person has been spamming variations on this comment for some time now and has never bothered to substantiate their claims.
