Noam Scheiber writes: “I have more botox in me than any ten people,” Dr. Seth Matarasso told me in an exam room this February.

He is a reality-show producer’s idea of a cosmetic surgeon—his demeanor brash, his bone structure preposterous. Over the course of our hour-long conversation, he would periodically fire questions at me, apropos of nothing, in the manner of my young daughter. “What gym do you go to?” “What’s your back look like?” “Who did your nose?” In lieu of bidding me goodbye, he called out, “Love me, mean it,” as he walked away.

Twenty years ago, when Matarasso first opened shop in San Francisco, he found that he was mostly helping patients in late middle age: former homecoming queens, spouses who’d been cheated on, spouses looking to cheat.

And that’s just what gets said in public. An engineer in his forties recently told me about meeting a tech CEO who was trying to acquire his company. “You must be the token graybeard,” said the CEO, who was in his late twenties or early thirties. “I looked at him and said, ‘No, I’m the token grown-up.’ ”

In talking to dozens of people around Silicon Valley over the past eight months — engineers, entrepreneurs, moneymen, uncomfortably inquisitive cosmetic surgeons — I got the distinct sense that it’s better to be perceived as naïve and immature than to have voted in the 1980s. [Continue reading…]
