I'm pointing out that current GUIs are pretty primitive and haven't undergone much serious thought about functional improvement since Xerox PARC in the late 1970s, and that's why TUIs can still have an edge with technically-inclined people.

It's not that GUIs are inherently worse in principle, but in practice they often are.

The point about overlapping windows is that that "desktop" model permeates the thinking about GUI design, but it's fundamentally limiting and misguided.

> we need complex (but not overlapping windows, sure!) interactivity and rich display capability.

Yep. Pity today's GUIs can't deliver that.
