The San Jose was a marvel of 17th century technology. The Spanish galleon weighed more than a thousand tons, was made of wood reinforced with iron, and featured three masts and 64 cannons. In its cargo were gold, silver, silk and porcelain. But in 1708, it sank after a battle with an English ship near what is now Colombia. For centuries, the shipwreck was the stuff of legends, until 2015 when underwater investigators found what they believed to be the San Jose's wreckage. The treasure on board this ship could be worth billions of dollars. But who owns it? Today on the show, four groups stake their claims to the wreck of the San Jose. Those claims reveal a lot about who has a say over the bottom of the sea and how we can begin to untangle the complicated legacy of colonialism.

On Monday, the stock market went into a tizzy over a new AI model from Chinese company DeepSeek. It seemed to be just as powerful as many of its American competitors, but its makers claimed to have made it far more cheaply, using far less computing power than similar AI apps like ChatGPT, Claude, or Gemini. In one day, hundreds of billions of dollars were wiped off the valuations of companies related to AI. This week, investors seemed suddenly to change their minds about what our AI future would look like and which companies will (or won't) profit from it. Will we really need all those high-end computer chips, after all? What about power plants to provide electricity for all the energy-hungry AI data centers? On today's show – how DeepSeek might have changed the economics of artificial intelligence forever. This episode was produced by Willa Rubin with an assist from James Sneed.
