This sort of thing sometimes causes people undue distress, as in the recent MIT Technology Review cover, featuring moonwalker Buzz Aldrin with the headline “YOU PROMISED ME MARS COLONIES. INSTEAD I GOT FACEBOOK.” But, in fairness, a Mars colony would cost a few trillion dollars, while Facebook is free. And, it’s worth noting that the choice of Facebook is a bit crafty. Imagine if they’d picked Wikipedia: “YOU PROMISED ME MARS COLONIES, AND ALL I GOT WAS ALL OF HUMAN KNOWLEDGE INDEXED AND AVAILABLE TO EVERYONE ON EARTH FOR FREE.
