Episode #69: Anthropic's Safety Reckoning, Jack Dorsey Cuts Block in Half, The Venture Consensus Addiction

E69 • Mar 5, 2026 • 22 mins

This week on The Learning Corner, Mia and Charles unpack the resignation letter of an Anthropic safety researcher who walked away from one of the most valuable companies in the world, alongside Anthropic quietly walking back its flagship safety commitment. They then dig into Jack Dorsey's decision to cut Block's workforce nearly in half, not because the business is struggling, but because he believes AI has fundamentally changed what it means to build a company. They close with a sharp LinkedIn post from Euclid Ventures GP Nic Poulos making the case that the venture industry has developed a consensus addiction, and the return data to back it up is hard to ignore.

Key Points

  • Valuations of early-stage startups have skyrocketed, yet data suggests that companies with lower initial valuations are more likely to yield significant returns.
  • The decision by Anthropic to walk back its responsible scaling policy highlights the tension between maintaining ethical commitments and staying competitive in the fast-evolving AI landscape.
  • Jack Dorsey's announcement of significant layoffs at Block underlines a broader trend of companies prioritizing AI efficiency and profitability, even at the cost of substantial workforce reductions.
