After nearly 30 years of tech life myself, I've come to the realization that the best UIs are not graphical. They can have graphical elements mostly for visualization purposes, but all of them should be as minimal and unobtrusive as possible. Any interactivity should be primarily keyboard-driven, and mouse input should be optional. Forcing users to click on graphical elements presents many challenges: what constitute…
The issue with this type of design is that it completely tanks discoverability. Every visual UI element trimmed is another pit of confusion for less-technical computer users. Modern UIs aren't great with discoverability, either however and are not an example that should be followed.
There are still ways to help, such as having a menu bar, and having good documentation. (Documentation is more important, in my opinion; but both are helpful.)
