Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds.

Just because your electronics are better than ours, you aren't necessarily superior in any way. Look, imagine that you humans are a man in LA with a brand-new Trujillo and we are a nuhp in New York with a beat-up old Ford. The two fellows start driving toward St. Louis. Now, the guy in the Trujillo is doing 120 on the interstates, and the guy in the Ford is putting along at 55; but the human in the Trujillo stops in Vegas and puts all of his gas money down the hole of a blackjack table, and the determined little nuhp cruises along for days until at last he reaches his goal. It's all a matter of superior intellect and the will to succeed.
