I don't remember asserting they would take over everywhere, just that they can function fine for content creation. By content, I did not mean "stuff created with a keyboard" and I think my second sentence makes that perfectly clear. Touchscreens are clearly not perfect multi-purpose interfaces. But I think you're ignoring the true significance of multitouch and other sensors and the additional dimensions of input that provides. A keyboard is nearly linear input. There's a lot of 2 finger chords and a smaller set of 3 finger keyboard chords, but for typing there's nothing really separating a 3 fingered man from a 10 fingered man except for input speed. Compare that to the capabilities of a 3 fingered man and a 10 fingered man playing the piano and you get the idea.
