Can we call this guy the most ignorant guy on earth?
Mmmm, no, not by a long shot. There are people with Youtube videos about bitcoin WAY more ignorant than him. Like for example that bald dude that someone has an avatar on here of, with an alien thingy stuck to his head. You'll find even more ignorance in the comments section of /. articles on bitcoin, too. Some of those posts are just painful to read.
I watched this guy when I first heard about bitcoin way back, when I didn't know/understand anything about it, and unfortunately didn't really bother to do my homework. Looking back, he is sooo incredibly beside the point, it is really laughable. Wouldn't want to be the company that hired this "bright" computer engineer, he looks and reasons like he was on SR too often....
