YOU EVER LAND A ROCKET?
"Who are you?
@elonmusk is landing rockets. He's landing rockets on robot drone rafts in the ocean — and you're saying he doesn't know what he's doing. Well, who else is landing rockets? You ever land a rocket? You're telling me he's an idiot. I just want to know who you are. So I know — why should I believe you as opposed to my friend Elon … and we're out here watching this rocket land? And that which I think is really cool. And you're there in front of your Apple Macintosh typing up an article saying Elon's an idiot."
Critics type. Elon lands.
Friend who builds > stranger who writes.
That's the achievement test.
