> "To me, this is like a Wright brothers moment," de Heer said. "They built a plane that could fly 300 feet through the air. But the skeptics asked why the world would need flight when it already had fast trains and boats. But they persisted, and it was the beginning of a technology that can take people across oceans."

Tangent: I always find comparisons to the Wright brothers kind of awkward, because everyone seems to overlook their subsequent patent war and how much damage that did to the aviation industry in general (tangent: similarly Edison really really stifled early innovation in lightbulb technology with patent trolling. Philips became as big as it is because there was a decade in the 19th century where the Netherlands didn't recognize patent laws, so was free to steal and combine every innovation out there. They also employed highly motivated former rivals of Edison whom the latter had put out of business)

Anyway, with that side-track out of the way: I don't want to sound to negative, I do hope this is the breakthrough it's hyped up to be!
