The wild emotionalism that has overflowed during Covid, is unlikely to go back into the container, unfortunately. It's a hellish birth child of the lunacy of the social media era meets rampant pandemic hysteria.
Software engineers (engineers in general actually) aren't special at all when it comes to being rational. They just like to think they are because of their field. It's identical to Stephen Hawking thinking he had special insight on politics, because he was gifted at one thing; or a famous actor thinking they have special insight on politics because they're gifted at one thing. Engineers are just as prone to failing to control their emotions properly, bouts of subject irrationalism and failing to strive for objectivity as is the typical person. Your typical software engineer on HN is no more rational than the typical plumber, the plumber is just likely more honest about it and less full of their self. You see it in every thread on HN, yet the rational engineer myth persists, amusingly.
