She was a ChatGPT skeptic. Then her parents died. Nov 06, 2026

Show notes

In 2024, Bridget Todd was facing down the hardest chapter of her life. Her father was rushed to the ICU after having a stroke. Then, a few days later, Bridget's mom died without warning.

Suddenly, Bridget found herself grieving, and trying to navigate the labyrinthian American healthcare system as her dad's primary caretaker, all while living hours away from her closest friends. Feeling isolated and overwhelmed, she turned to ChatGPT, and ended up telling it everything.

Bridget is a tech critic and journalist, and the host of the podcast "There Are No Girls on the Internet." She's also the co-author of the audiobook Love at First Prompt: AI and the Future of Intimacy. After interrogating her own relationship with a chatbot, Bridget investigated the trend of AI companionship more broadly. She learned the true stories behind click-bait headlines about AI fiancés and reconsidered her own bot rapport.

Ben and Amory talk to Bridget about what we have to lose when we outsource our emotions to LLMs, and if there's anything to gain.

Endless Dread: The Mysterious Lagoon Oct 23, 2026

Show notes

Lagoa Misteriosa, or Mysterious Lagoon, is located near the small Brazilian city of Jardim. Surrounded by lush jungle, the surface of the lagoon looks like azurite — still as glass and crystalline. Its waters are so clear, looking down you might expect to see the bottom, except... the bottom of Lagoa Misteriosa has never been found.

Today on Endless Dread, our annual witch's hat tip to spooky season, Amory takes Ben deep down into the story, and mystery, of Lagoa Misteriosa. The story for Amory began on Reddit in r/thalassophia, a community devoted to the fear of deep water.

ChatGPT's human editors Oct 16, 2026

Show notes

Up to a billion people use ChatGPT every week, for everything from the mundane to the weird to the deeply personal. It is commonly assumed that these messages are private – between the user and the LLM. It is commonly assumed that these messages are private – between the user and the LLM. But in some cases, human reviewers are reading these conversations and offering editorial feedback to help ChatGPT sound more human.

Reporter Joseph Cox of 404 Media broke the story of Project Lily, Open AI's initiative to use human reviewers to train and improve ChatGPT. He breaks it down for us on this week's Endless Thread.

Remembering Brooke Eby Oct 09, 2026

Show notes

"Should I be joking at a time like this?"

That's the question then 33-year-old Brooke Eby asked herself when she uploaded her first piece of TikTok comedy in 2022, about being diagnosed with a terminal illness. Brooke built an audience of hundreds of thousands of people who were rooting for, and laughing with, her. Sometimes it got weird.

Brooke died due to complications with ALS earlier this month. She was 37.

In 2025, she talked to Endless Thread hosts Ben Brock Johnson and Amory Sivertson about how facing death changed her relationship with social media and online community.

Mixed signals: Nextdoor villains and the holiday you've never heard of Oct 02, 2026

Show notes

The internet is the great connector. Talk with nearly anyone at any time about anything. But that kind of freedom can lead to misunderstandings. Maybe your neighbors discover your cruder, less friendly persona online. Maybe a debate over holiday lore becomes a battle front.

Endless Thread producers Grace Tatter and Frannie Monahan bring two stories to remind us that the internet is a morass of information that no one can ever control.

The Haruhi problem Sep 25, 2026

Show notes

Get out your graphing calculators, because today's episode of Endless Thread is about a math problem. Specifically: wt(π1, . . . , πm) = m−1 ∑ i=1 wt(πi , πi+1) Now, pencils down. Stumped? So were mathematicians for decades. That is, until the equation was solved in a thread on 4Chan about watching the anime The Melancholy of Haruhi Suzumiya. Show notes:

Keeping the Lights on at a Video Game Cafe in Southern Yemen Sep 18, 2026

Show notes

Mo lives in Aden, an ancient city in southern Yemen. Built on a volcanic crater, it has castles and beaches set against mountains. It's beautiful. Like the rest of the country, it is also in the midst of an ongoing civil war. This summer, protests broke out over living conditions and basic services in the city -- like electricity, which can be shut off for 18 hours at a time.

But despite these conditions, for the last five years, Mo has been fighting for a persistent dream of his –– a video game internet cafe for his neighborhood. This week on Endless Thread Ben and Amory tell the story of how Mo, against all odds, has kept the lights on (quite literally) at his gaming cafe thanks to his persistence, and the help of internet strangers across the world.

Ear rumblers assemble! Sep 11, 2026

Show notes

Ben can make a roaring, rumbling sound with his ears that no one else can hear. He never thought much about it — whether only he could do this, or whether everyone could do this — until he discovered a subreddit called Ear Rumblers Assemble: a whole community devoted to the mysterious and understudied ability to voluntarily tense one of the miniscule muscles in our ears.

We go into Ben's ear with Dr. Anand Devaiah, and raise questions about how everyone experiences the world differently and the enduring mysteries of the human body.

Encore: Owl pursuits Sep 04, 2026

Show notes

This episode was originally published on March 10, 2023.

In 2022, freshmen at the University of North Carolina at Chapel Hill got a new neighbor: an owl. What wasn't clear was whether the owl was trying to befriend them, or catch them.

Sometimes the owl seemed to be chasing students. Other times, it seemed to come in peace. A popular campus Instagram account reported that a woman had actually raised the owl herself. After she was spotted feeding it, the owl sightings stopped, much to the disappointment of students who'd come to consider it as a sort of mascot. Where had the owl come from, and where did it go?

Endless Thread host Ben Brock Johnson and producer Grace Tatter talk about how the owl gained online campus fame, and get a surprise update from the person who knows the owl best.
