The young lady interviewing him is "LadyAda" (Limor Fried) who is the founder of adafruit industries, the notable Arduino crap shifter and former MIT media lab graduate. When this video was originally posted it annoyed the hell out of large swathes of people on the Internet because she kept interrupting him. I'm a vicious opponent of her as under the guise of open source, she pushed for price hyping of trivial products and marketing then whined a lot when the Chinese copied the open source stuff and undercut her by several orders of magnitude.
Good videos though. Thanks for posting
