This is easily the most spot-on comment I've read on HN in a long time.

The humility of understanding what you don't know and the limitations of that is out the window for many people now. I see time and time again the idea that "expertise is dead". Yet it's crystal clear it's not. But those people cannot understand why.

It all boils down to a simple reality: you can't understand why something is fundamentally bad if you don't understand it at all.
