I do aggree that it's pretty high bar in this case though - it's changing the flow, not just improving it. So it'd have to get very polished to be able to compete, which I just don't think it will.
Still, maybe someday.
My whole point is that this is not an improvement, it's actually a worse way to enter a simple datastructure into the computer. It's even worse than using the already established UI paradigm of programs like Paint. Picking a tool and dragging out a box is faster, because you don't have to learn the visual language of how to draw these widgets.
It does look cool, because it makes the computer appear smart, but it's just not a good interface for actual use.
