How Afraid of the A.I. Apocalypse Should We Be? Eliezer Yudkowsky is as afraid as you could possibly be. He makes his case. Yudkowsky is a pioneer of A.I. safety research, who started warning about the existential risks of the technology decades ago, – influencing a lot of leading figures in the field. But over the last couple of years, talk of an A.I. apocalypse has become a little passé. Many of the people Yudkowsky influenced have gone on to work for A.I. companies, and those companies are racing ahead to build the superintelligent systems Yudkowsky thought humans should never create. But Yudkowsky is still out there sounding the alarm. He has a new book out, co-written with Nate Soares, “If Anyone Builds It, Everyone Dies,” trying to warn the world before it’s too late. So what does Yudkowsky see that most of us don’t? What makes him so certain? And why does he think he hasn’t been able to persuade more people?

The government shutdown is the Democrats’ first big strategic bet of Trump’s term. Not everyone in the party agreed that shutting down the government was the right move or that health care was the right message. So why did they ultimately pick this fight? What are the risks? And what could Democrats learn here that might help shape their strategy for the midterms and beyond? Jon Favreau, a former Obama speechwriter and a current co-host of “Pod Save America,” joins me to discuss.

There’s a serious high-stakes policy fight at the heart of this. The Democrats didn’t pick a fight over authoritarianism or tariffs or masked immigration agents in the streets. They picked one over health care. And the issue here is very real. Huge health insurance subsidies passed under President Joe Biden are set to expire at the end of this year, threatening to make health care premiums skyrocket and kick millions off their insurance. Neera Tanden was one of the architects of the Affordable Care Act and has worked in Democratic policymaking for decades. She is the president of the Center for American Progress and was a director of Biden’s Domestic Policy Council. I asked her on the show to lay out the policy stakes of the shutdown and what a deal might look like.
