I don't agree that he is making good points. He is making points that are of the current mindset. I can see myself and others like me easily transition to that type of interaction until the next generation of customers, aka, kids grows up knowing and feeling comfortable interacting in that or a similarly smart manner.

I do think that the gestures could be broken out into additional interactions, e.g., gestures towards the top do a different thing than the same gestures at the bottom or even have four quadrants that initiate different interactions.

I would think that it would require a type of introduction and practice mode that progressively teaches how to interact and also allows a demo mode like display that can be engaged for those who are not versed in that type of interaction. If not being intuitive was really an impediment there would be no keyboard shortcuts. If you can't take a second to memorize some keyboard shortcuts that will quadruple your effectiveness and efficiency then you cannot be helped.
