God forbid someone learns business and has produced multiple successful businesses in some of the most forward looking, technical fields. That does not immediately disqualify their ability to know technical topics and if even may signal quite the opposite. This level of elitism often among the HN crowd creates an echo chamber that stifles innovation since it arbitrarily discriminates the dissemination & mixing of ideas that aren't fully "technical". These guys understand the concepts and can communicate with each other with that shared understanding and constructs. It's wild but that's how the top people within the field may chat, simply, efficient, and pointedly.
