If I formed my opinion only from HN, I'd think most engineers love: big-tech, advertising, electric cars, Apple, tech-enabled tracking (autos, web, cell-phone, watches, exercise machines, music players - it's ok if business profits!), and tend toward self-righteousness, narcissism, and virtue-signalling.
Of course, most of us are just living our lives and trying to get by. I don't know where this self-important insufferable attitude comes from, but I suspect it's a few folks who are very noisy. Most 'normal' people don't spend much time posting to sites like these, so there is a selection bias. Sadly, I also suspect that this attitude is an advantage in today's environment. It is a mirage of self-confidence, and telling the two apart can be very hard (especially for a potential employer).
