That's great, but keyboard shortcuts are not exclusive to TUIs. GUIs can be just as powerful in that sense, and most advanced web apps support keyboard navigation. My objection is mainly to the claim that TUIs are beautiful, and to the effort of bringing their design to the web. But this is ultimately down to personal preferences, and others may disagree.
Yes, GUIs and Web interfaces can support keyboard navigation. But I have NEVER found one fully exploiting this. Linear (ticket tracking app) is maybe the only one that comes to mind as a good alternative, but nowhere close to the fluidity achieved by TUIs.
I think the reason is "limitation", if you have to design an app that CAN NOT use a Mouse, you'll be darn sure it'll work well with the keyboard.
You’re correct that modern web apps support keyboard shortcuts just fine. Unfortunately the reality of it is that the modern web is bogged down by the mess that is npm modules, react etc, and the majority of web apps are slow. Oldschool terminal apps you can just type away, and you know your keystrokes will just happen. The modern web? Urgh.
Don’t get me wrong, you can do it right, but most don’t bother with non- functional requirements “this should take 5ms” etc, so you just end up with pointless animations and transitions that stop useful work being done. This is often simple things like the tab order being wrong, or an AJAX request blocking the next thing you want to do.
Its true in theory, but it does not work well in practice because:
1. Developers have to make an extra effort (and require time) to do it right
2. People are much less likely to learn the keyboard shortcuts
If you designed a GUI to be keyboard first then it might work as you say, but I cannot think of any real life examples of that. I think people need to TUI look to push them to use keyboards.
