"Scared, the eggheads. And maybe that’s how it should be. They should be even more scared than the rest of us ordinary folks put together. Because we merely don’t understand a thing, but they at least understand how much they don’t understand. They gaze into this bottomless pit and know that they will inevitably have to climb down—their hearts are racing, but they’ll have to do it—except they don’t know how or what awaits them at the bottom or, most important, whether they’ll be able to get back out."
