Lesson 1: All GUI frameworks suck. This follows from
Lesson 2: All GUIs suck.

GUIs are all designed with specific usage scenarios in mind. However,
people’s use of computers evolves over time. So the GUI has to evolve
to keep up. Which means it inevitably loses more and more of its
original integrity and simplicity.

Or, in other words, there is no such thing as a universal GUI.

Isn’t there a contradiction in terms there somewhere?

If you don’t need to get it right, then, say, one lifetime ought to be
enough.

If you need to get it right, then you will never finish.
