You're familiar with the phrase "Man's reach exceeds his grasp"? It's a lie. Man's grasp exceeds his nerve. The only limits on scientific progress are those imposed by society. The first time I changed the world, I was hailed as a visionary. The second time I was asked politely to retire. The world only tolerates one change at a time. And so here I am. Enjoying my "retirement". Nothing is impossible, Mr. Angier, what you want is simply expensive. [1]
