I think what we need is unix/shell-like GUI.

CLIs all have the same consistent user interface. Positional arguments, flags, and text output. On unix-like envs they also have pipes. This is why people like them. This is what makes people productive in them.

Sure, modern GUIs have a few shared UX paradigms, but largely they are all different.

I wonder how the unix philosophy applies to GUIs? Or what the early developers thought about it. How would piping work in a GUI.
