Proton: Multitouch Gestures as Regular Expressions [pdf]

When the basic essential interactions like "select" feel natural and unambiguous -- holding your hand in place for Kinect wasn't a good replacement for "click"/"tap".

I've done a lot of full 3D gestures work. They work well, but people are finding it hard to come up with workable interactions to care about/spend battery on.

Google's new stuff had an opportunity to move gestures off the screen, mostly because it is low power/localized rather than high power/installations/invasive.

The Kinect as-is really had no future. It was too limited for gaming and too clunky for anything else. I do think the tech is great - if not amazing, but only if its part of a larger pie. MS's Hololens with a Kinect reading your body/hands/face/fingers makes a lot of sense to me. AR that's aware of your every move can be big, perhaps even a game changer in some/many industries.

At my desktop, I really don't need anything like Kinect. I can type on a keyboard or use a mouse. Or swipe on the nearby screen. Gesturing is clunky in those scenarios. Now put an AR headset on my face and set me loose. Now I need some kind of remote input that I don't carry around. That's something AR needs and MS has a major lead here.
