Too much Elon Musk. He's beginning to exhibit signs of a cult of personality. https://en.wikipedia.org/wiki/Cult_of_personality

Wait, we can print TITANIUM? Up until now, I thought 3D printing only involved plastics...

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.

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.
