Mark Zuckerberg's 7-year-old daughter told him she wanted to be Taylor Swift when she grew up. He looked at her and said you can't, that's not available to you. Sounds brutal for a dad to say. But Zuckerberg built a $1.4 trillion company on the exact impulse he just shut down in his own kid, and he understands that impulse better than anyone alive. There's a French philosopher buried in this story. René Girard taught at Stanford, and his big idea was that desire is borrowed. You don't independently decide to want a Birkin bag or a corner office or a pop star's life. You see someone else wanting it, and you catch the wanting like a cold. He called it mimetic desire. One of his students was Peter Thiel. In 2004, Thiel wrote Facebook's first outside check, $500K for about 10% of the company, and he has said Girard is a big part of why he saw the bet. A website where millions of people watch each other's lives is a machine for showing you what everyone else wants. The theory said it would be irresistible. That $500K turned into more than a billion dollars. Every feature since runs on the same engine. Likes show you what others approve of. Followers show you who others watch. The feed is a 24/7 broadcast of other people's wants. So when a 7 year old comes home from a concert saying she wants to be Taylor Swift, Zuckerberg isn't hearing a cute dream. He's hearing the force he's monetized for twenty years, pointed at his own kid. And his answer was the one move Girard said actually breaks the loop. Stop copying the model. Become the model. His daughter thought about it and decided she wants people to want to be like August Chan Zuckerberg instead. He sells the itch to be someone else to more than 3 billion people a day. The one person he coached out of it was his daughter.
