In 2018, Elaine Herzberg became the first pedestrian to be killed by a self-driving car. But who is to blame? We prosecute the person who was behind the wheel at our own peril.

Elsewhere: short-term cryo has put Cass and Icarus in a relationship crisis.

(Note: this is an updated version of the Bellwether pilot, originally released in 2019)

Featuring: Jennifer Morrison (National Transportation Safety Board, formerly), M.C. Elish (Data & Society), Raj Rajkumar (Carnegie Mellon University), and Chris Urmson (Google formerly, now Aurora)


After a deadly fire at an Oakland arts space called The Ghost Ship, cities across America responded by cracking down on unofficial live-work spaces. Alt-right internet trolls took notice, and launched a culture war, pitting local governments about the people they are tasked with keeping safe.

Elsewhere: Icarus and Cass learn of an autonomous Juggalo community, and hear from an autonomophobic blogger back east.

Featuring: Geyl Forcewynd, Dan Weiss (The Yellow Dress), Gabriella Coleman (McGill University), and B. Rouse (UC-Berkeley)


A law that was supposed to stop sex trafficking is making life more dangerous for the people it’s supposed to protect. It’s also collapsing the entire internet.

Elsewhere: Icarus and Cass call on a spurned lover, who reveals that there's more to Bellwether than meets the ear.

Featuring: Sarah Fenix, Melissa Mariposa (Red Umbrella Hosting), Liara Roux, and Vex Ashley (Four Chambers).

04_KEEP IT 200

An autopsy on a dead link, and the anthropology of trying to find transgender health care at Kaiser Permanente in Los Angeles.

Featuring: Clare Stanton (Harvard Library Innovation Lab), Anne Petersen (18F), and Kathy Tu (Nancy podcast forever).

/** ABOUT **/

BELLWETHER is a podcast of speculative journalism created by Sam Greenspan. Bellwether presents stories of the world as it is through the lens of what it might become: in-depth longform nonfiction, told within the frame of an ongoing sci-fi radio serial.

Within the show’s nonfiction, host Sam Greenspan reports true stories of collisions with technology. A person is killed by a self-driving car. An online hate forum weaponizes municipal code compliance officers. A moral panic results in legislation that is collapsing the internet. A 404 “Page Not Found” error initiates a medical disaster. The stories are, in a sense, true stories of real people caught in real-world dystopias.

Bellwether’s fiction centers on Cass (Carmen Berkeley), the sentient A.I. companion of a human named Icarus. The pair are currently in the largest city in North America (Phoenix, Arizona), holed up in short-term cryogenic freezing (it’s the only place they can afford). They’re doing gig work for the “Cloudburst Truth & Reconciliation Commission”—a joint effort of A.I. and humans (or biological intelligence, or “B.I.”) to figure out what caused the internet to permanently disappear two decades prior.

Cass and Icarus’s job is to sift through the wreckage of the internet, and tag anything interesting they come across. Cass, the curious A.I. is in heaven surrounded by all this data. But Icarus is homesick; he is sustained on “copperwire” voice messages left for him by his family back in Kansas: Icarus’s moms (Katie Malia and Pooya Mohseni), his Uncle Ernie (Michael Chernus), and his grandparent (Keith Randolph Smith).

Icarus resolves to quit the Cloudburst T&RC and bring the pair back to Kansas. But on their last night on the job, Cass and Icarus come across a few artifacts—episodes of an old early-21st Century “podcast” called Bellwether. They begin to wonder if Bellwether might hold clues to figuring out what happened to the world—and maybe, how to save it.
