Ya he reinvented himself. Mechanical Engineering degree from Cornell University, He was a design engineer at Boeing for 9 years and as of 2020 has a net worth of 8 million. Say what you want about the guy he's not stupid.
Maybe he designed the Blinker fluid on the Boeing 737 Max.... I dunno, never heard of the guy. Won't change my mind..... Just another expert on being an expert IMO.....
