What do Airbnb, Facebook, Spotify, and LinkedIn all have in common? Peter Thiel. They made his fortune, but he’s since rejected Silicon Valley for being too "woke". He’s a contradictory character: a libertarian who made billions from big state surveillance; an intellectual who purports to hate politics, but who’s poured millions into political campaigns, including Donald Trump’s 2020 bid. Some call him a free-thinking genius, while others say he wants to watch Rome burn. Simon Jack and Zing Tsjeng tell the intriguing story of Peter Thiel, the man who ousted Elon Musk from their company PayPal, and who’s signed up to be cryogenically frozen. Then they decide if they think he’s good, bad, or just another billionaire.
