A message from ‘Impromptu’

From AI-generated scams that cost Americans hundreds of dollars to voice cloning schemes, the line between real and fake is becoming harder to detect. At the same time, technology companies are setting their own limits on how these artificial intelligence tools can be used. This is raising new questions about who really controls this technology — and what that will mean for our future.Host Megan McArdle is joined by Dean Ball, a senior fellow at the Foundation for American Innovation and former White House AI policy advisor, to unpack the rapidly shifting landscape of AI governance, what it will take to rein it in — and what comes next. Subscribe to The Washington Post here.

Until recently, universities were widely seen as places for asking questions, debating ideas and accessing upward mobility. Now, they’re just as likely to be seen as battlegrounds in the culture wars. As public trust eroded and political scrutiny intensified, a bigger question emerged: When did this shift happen? And more importantly, can it be repaired?Host Megan McArdle is joined by Daniel Diermeier, chancellor of Vanderbilt University. He is trying to answer those questions not just in theory but in practice. Drawing on his experience leading a university, Diermeier shares where he thinks universities have gone off course, what needs to change and what’s still worth protecting — and whether they can once again become places where more people feel they belong.Subscribe to The Washington Post here.

This week, we celebrated Presidents Day, which makes it a fitting time to recognize one of America’s most underrated presidents. Herbert Hoover presided over the onset of the Great Depression and is widely viewed as the inferior predecessor to Franklin D. Roosevelt. But, as host Megan McArdle explains, that judgment is unfair to Hoover. It also reflects a larger problem: the assumption that a president can singlehandedly fix or wreck the economy.Subscribe to The Washington Post here.
