Though I would disagree with his personality built on being right - it’s built on being a futuristic visionary problem solver. Whether he’s actually solving problems, and whether they even need to be solved, that’s up for debate.
He states at least once that he is wrong all the time. At other moments he says other similar things (but sometimes more related to engeneering for example: “All designs are wrong… just a matter of how wrong”).
But I have to agree, before seeing that video I didn’t see him being so open to being wrong, and also not as technically involved or at least knowledgeable…
"Step one: Make the requirements less dumb. The requirements are definitely dumb; it does not matter who gave them to you. It’s particularly dangerous when they come from an intelligent person, as you may not question them enough. Everyone’s wrong. No matter who you are, everyone is wrong some of the time. All designs are wrong, it’s just a matter of how wrong."
