>he knows what he is talking about when it comes to rockets

At a surface level. If you ever drill down on his shallow tech understanding, he sputters, kicks you out or flees.

No, at the level of knowing off hand the design considerations down to thermodynamics for practically every design decision that Tim asks about. In many cases to a much greater depth than I, an average engineer, know about these things.

He can regurg briefings, look again at what he says in anything you’re an expert in. E.g. software: he’s a total fraud.

This comment is ridiculous. The guy understands every single facet of every process at his companies. If he "sputters," it's because that's how he normally speaks.
