I look at how spending $8 billion can either buy you $3 billion of revenue from Ingenico, or the private valuation of Robinhood and/or Revolut. Would you rather have a massive cash-flow machine, or a venture bet on a Millennial investing meme? To articulate this question in more detail, we walk through the impact behavioral finance has had on economic rational actor theories, and why quantitative financial modeling often similarly fails to capture the underlying tectonic plates of industry. It may not be wrong to bet on Millennials. We talk about what identity economics (ala identity politics) means for market value and how to think about generational change.
