Bill Sloman
Sloman is pathetic. He keeps telling us how smart he is and how dumb we are but hasn't been personally productive in decades. He's been trying to build a useless oscillator for 10 years or so now.
I've not worked since 2003, so I've not been all that productive for one decade, not decades, and the useless oscillator really is useless - in the sense that I don't have any immediate application for it - but I started working on it around the 14th February 2012, which is eighteen months ago, not ten years.
Larkin's grip on reality is tenuous. Just as well - he'd have trouble maintaining his inflated ideas about his own competence if he had better understanding of the outside world. It would probably drive him into a lethal depression, and put his employees out of work. Some delusions can be useful.
