I put 80% of my money in the S&P after Howard Marks told me not to

"What they're saying is that's all wrong. The AI should make the decision and the humans should be around the AI and the AI should be the company brain. We're the line now. We are the line. We are the nodes. We are just giving it new information."

Jack Dorsey and other tech leaders are restructuring companies so AI serves as the central decision-maker rather than human assistant. This inverts the traditional model where humans make decisions and AI provides information. Dorsey laid off tens of thousands at Block to implement this structure where employees feed context to AI which then makes faster, less biased decisions. The shift represents a fundamental reorganization of corporate hierarchy around machine intelligence.

About this episode

In this episode of My First Million, hosts Sean Puri and Sam Parr explore how genetics shape financial behavior and discuss paradigm shifts in AI deployment and corporate structure. The conversation opens with a Swedish twin study claiming 45% of investment behavior is genetically determined, analyzing biases like excessive trading, home bias, and refusing to sell losers across 30,000 twin pairs. Puri and Parr debate whether such research is useful or limiting, with Parr favoring productive placebos over deterministic conclusions. They examine investor Mohnish Pabrai's transformation after personality testing revealed his ideal zone as solo, competitive, numbers-based work, leading him from mediocre entrepreneurship to investment success. The discussion shifts to Jack Dorsey's radical restructuring at Block, where AI becomes the decision-making brain and humans serve as information nodes—inverting traditional corporate hierarchy. They cover Citrini Research's controversial prediction that AI productivity gains will collapse the economy by gutting white-collar jobs and consumer spending, triggering major market sell-offs. The episode explores YC's Request for Startups including aesthetic data centers to combat NIMBY resistance, drone swarm defense as the new warfare paradigm, and AI-powered personalized medicine. Dramatic examples include former GitHub CEO Nat Friedman allowing AI to control his Tesla route for supplement purchases and GitLab CEO Sid reportedly using AI to treat his cancer with encouraging results. The hosts conclude that technological ground is shifting again, similar to past waves from social networks to marketplaces to crypto, with hard tech, defense, and AI management representing the new frontier.
