Sure it is, if you have no idea if your knowledge is actully usefull and you push it anyway.

Just imagine how you feel if someone, say a consultant or a agile master, shows up at your work and tells how to do your job without having any experience with it, or the environment you are doing it for. There are even multiple threads on HN every week accusing those consultants of hubris in various ways.

Correct, it definitely can be if it’s unsolicited advice and/or if the “knowledge” is low quality, incomplete, difficult to apply, or just ignorant of Chesterton’s Fence.

Let me drop by your workplace and tell you how to do your job. And call you ungrateful when you don't listen to me. I mean, I have no idea what you do for a living and you have no reason to believe I have some special expertise you lack. But hey, free knowledge right?

Yep, snooty early 20-somethings flying halfway across the world to teach people with hundreds years of experience.

For sure that's not just virtue signaling and youthful delusion. For sure.
