I have met him in person a lot of times: I worked at a local electronics shop and we used to bring him TVs and radios for repair regularly. He was socially awkward, stubborn, and on more then one occasion he made mistakes with regards to the repairs but did not want to admit fault at any time. From my (rather limited) interactions with him, I'd say he was far from genius, I feel he just got sucked in and had no way out of his network of lies without losing face.
