>"Nobody knows what they're doing".

How can you possibly make this assertion? I have a direct counterexample; I know what I'm doing. There's a lot of stuff I don't know, but I would not describe my state of being as "not knowing what I'm doing".

>everyone to a degree doesn't know what they're doing

This is very different from "Nobody knows what they're doing". Just because no one has a perfectly clear idea of everything doesn't mean they don't know what they're doing.

You are absolutely right about the title. Though, I should probably clarify, the more accurate title would be "Nobody knows what they're doing all the time." That was the intent when I wrote it, but it could be argued that if the title weren't a bit sensationalist, we may not be having this meaningful discussion with points and counterpoints on HN right now.

EDIT: Actually "all the time" doesn't quite cover it, I'd say it's "most of the time".

"I know what I'm doing." - No, at some level, you don't know what you're doing. And I bet that, in certain situations, you act like you know what you're doing. Or, perhaps you didn't know that you didn't know what you were doing.
