People who compete want to get recognition for their accomplishments. "Getting off this rock" has so far been led closer to becoming true by cold hard competition. So sorry bud, people will always want credit for their success whether you like it or not. And hey, who said we won't get off this rock during the process of all that?
That, and I want to see an Epic Rap Battle of History between Musk and Bezos some day. It will take a lot of competition and a lot of progress before they have enough dirt to throw at each other.
