A.I. is becoming smarter without much help from humans, and that should worry us all. Nate Soares, president of Machine Intelligence Research Institute (MIRI), joins host Krys Boyd to discuss what happens when A.I. brain power surpasses what humans are capable of, why we don’t have the technology yet to understand what we’re building, and why everything will be just fine … until it isn’t.

Autocrats are famous for enacting vague laws with specific punishments – and if people preemptively overcorrect their behaviors, all the better. Matthew Purdy is editor at large and writer for The New York Times Magazine. He joins host Krys Boyd to discuss why the Trump administration has intentionally created vagaries around tariffs, D.E.I. and other areas so that it is difficult to know if one is breaking the law – and how that helps to consolidate presidential power.

When you pop open your medication bottle and take your pills, you assume they are safe. But how do you know?
