So which one is the novel contribution here? I get that he is combining a bunch of EXISTING technologies, but does he need to be in the video? Are his motives just to show off the technology HE invented or just a way to publicize his company and his name? I have seen many projects where they control objects in the computer with hand motion (and even gesture) like this.<p>I'm sick of people worshiping folks like him or Jobs for no apparent reason. I get that he's risk-averse and is willing to put his money into innovative ideas, but it's not like they're all coming out from Musk.
