Yeah there's a pretty common routine of SpaceX & Tesla having some of the best results in the world for what they are trying to accomplish AND being much worse than what was promised.
And that's one of the (many) frustrating things with Musk: he fairly consistently overpromises and underdelivers. Even if that underdelivering is better than what you can get elsewhere, it still leaves a bad taste in people's mouths.
It definitely does, although I don't understand why.
One thing making bold forecasts does is motivate your people. JFK told us we'd get to the moon this decade which is absolutely nuts. Would we have got there as soon if he had said we'd get to the moon eventually?
To the other responder: JFK also had no tangible justification to say we'd get there so soon, and the most likely outcome was that he was going to be wrong. Does that make him a pathological liar?
