I think your mistake is thinking that this is a roll of the die. Just because something is difficult to discuss doesn't mean there aren't people that understand it. And many pro-Tesla arguments are systemic, which also makes them difficult to convey (concepts like "game-theoretic equilibrium" are not in common lingo). Many pro-Tesla-ites will sound hype-y because they don't have a good way of explaining their conclusions, not because they don't have a clear understanding.
