Just stumbled on this thread and thought I'd add my 2 cents...
As someone who has been around people for many decades, there's one thing I've learned about people:
Never, ever, EVER challenge, correct, or criticize anyone. Ever.
Why?
Ego. Few will admit it, but we are all, for the most part, driven primarily by egos and our feelings. It feels good to boost our egos, and it feels incredibly painful to hurt our egos. Some more than others, but for the vast majority of us protecting our egos is on the top of our list of important stuff.
And truth be told, the vast majority of tech (and other) discussions boil down to egos. I'm smarter than you. That's it.
And since, by definition, suggesting something like that will hurt peoples' egos, most people will absolutely freak out when they read that. Or say it's just the other guy who's that way. But that's just further proof that it's true.
Psychologists have known that it's true since the beginning of time, but it's one of those things that's too painful to discuss. Or admit.
Personally, I know I'm that way, but I've also learned enough to realize that, after more than 45 years as an electrical engineer, I don't know nothin'. Always learning, every day. So when someone disagrees with or challenges me, it initially hurts, but I also realize they may be right and it might be a chance to learn something. Of course, they may also just be trying to protect their egos and prove they're smarter by saying some irrelevant tech factiods, but anyway...
So as my signature says, the smartest people are those who know enough to finally realize "hey, there's a TON out there that I have no clue about".
Coincidentally, I just saw an ad with Neil deGrasse Tyson where he said something like:
"One of the great challenges in life is knowing enough to think you're right but not enough to know you're wrong".
Oh, and another well known but never discussed (and related) topic is:
"People believe what they want to believe. Facts are irrelevant". And as a psych professor buddy told me years ago, "and that especially applies to technical folks like scientists and engineers".
