I'm impressed by the kid's engineering and gumption, but I think he's a bit.. misguided, if you'll pardon the pun. The video ends with shots of Russian drone war, and, bizarrely, photos of David Koresh.
I don't think this ends well.
You're omitting that the end of the video also features pictures of Martin Luther King, Vietnamese civilians during America's invasion of their country and Afghani Mujahideen freedom fighters during the Soviet Union's invasion of theirs; I think he's trying to make a point about technology enhancing the capabilities of people who are in any conflict with conventionally powerful forces, not an endorsement of David Koresh.
Out of five and a half minutes of video, David Koresh appears for perhaps three seconds.
It does put a new twist on the recent controversy about 3d printers needing to be licensed, however.
edit: Ok, I googled the guy

and Ted Kaczynski who believe that technology is harming us and the world.
