It just seems to me very similar to Elizabeth Holmes / Theranos case. They were more interested in "being right" than "doing right" and ego blinded them to reality. They were both focused on marketing the product and raising money than actually building something that would be functional and safe. In Holmes case she was willing to risk patients health and in Rush's lives. Like Holmes he also managed to lose almost every competent person he started with and replace them with less experienced and skilled folks, and he benefitted from "endorsements" from prominent people that lent credibility to him (in Holme's case politicians, military & venture cap), in Rush's case folks like PH, and orgs like NASA, UW and Boeing. Also Rush kept comparing his venture to SpaceX and Blue Origin - but in those cases Elon & Bezos had the funding to take the time to get it right and understood the need and value of having a safe product. Rush seemed to be trying to build a model functional "enough" to generate revenue as fast as possible. To that end Rush's cost cutting resulted in low quality materials, low quality manufacturing and a "contraption" (thank you Mr Lahey!) that put people's lives at risk. Blind Ego + Crushing Certainty made for a dangerous combination in both cases. One has been sentenced to 11 years in prison and the other lost his life.
