DAVID BASZUCKI QUOTES FROM THE INTERVIEW

“[Our son with bipolar] tried a ketogenic diet, and literally within three weeks or four weeks, we saw progress that we had never seen with any drug or medication. Mind blown, really, and a miracle.”

— David Baszucki

“One other way to predict the future, I think, is many things are just inevitable. There are enough smart people around that the wheel was inevitable.”

— David Baszucki

“Roblox was always what is called a user-generated content platform, which means creators are making stuff, people are learning STEM, people are getting excited. Even the ego burst of having three friends play a game can really motivate a young person to get into computer science.”

— David Baszucki

“If you’re having a mental health crisis, work on your body and your machinery, maybe, before you work on the talk therapy. Get the strategic things right first.”

— David Baszucki

“If we were to tabulate the number of new entrants into computer science or graphic arts or economics that had been inspired by Roblox, it probably is in the millions, given just that experience that people have had on our platform.”

— David Baszucki

“What’s interesting is I’ve never really ever liked any business books ever. … The books I was obsessed with in my youth were the books about Magellan and Captain Cook and Mutiny on the Bounty and Joshua Slocum and just all of these crazy explorers, Amundsen and Scott and all of that stuff.”

— David Baszucki

Dear Tim,
I hope you know that Baszucki is currently in a lot of hot water for many of the choices he’s decided to make within the Roblox community, his moderation, and many people (myself included) agree he is in the wrong. Look into it.

It would be really great to get the actual makes and models of the continuous glucose monitors and continuous ketone monitors.

Especially the ketone one as I’m in Canada!

During my nightly insomnia wake up at 3:00 am I put this podcast on with a 30 minute timer and fell back to sleep within 15 minutes (no offense Tim). Learned something as well. So yep, this works for me too.

Hi Tim — long-time listener and big fan of your work. I’m a radiology resident in South Florida with an interest in neuroradiology, and I’ve been following your discussions about ketogenic strategies for Alzheimer’s disease with a lot of excitement.

One idea I’d love your thoughts on: using PET/CT imaging with amyloid tracers like Amyvid (florbetapir) to directly measure how ketogenic diets might influence Alzheimer’s pathology over time. A well-designed study could track changes in cortical amyloid burden before and after a sustained ketogenic or ketone-supported intervention, paired with cognitive testing and metabolic markers.

Given your interest in this space — and the growing scientific momentum — this could be a powerful way to generate objective data. If you think this direction has merit, I’d be thrilled to help shape a pilot design or connect with researchers in your network who might be exploring similar questions.

I’ve been following Tim since the 4 Hour Work Week and the podcast since one of the first interviews (w/Joshua Waitzkin). This is the first interview I’m genuily confused to see published. Roblox has such a well documented past/present of failing to protect kids from child predators, fostering extremism, and sitting idly while the absolute worst human behaviors happen in excess on the platform. I know Roblox’s digital civility team is top notch at putting a silver lining on this stuff but Tim’s camp always does it’s research and the platforms problems are very very well documented. IMO this one was a huge miss.

I’m deeply grateful to David for his willingness to share his son’s story—and to his son, even more so—around a topic that is so often surrounded by secrecy and shame. This is an incredibly powerful and generous conversation. Thank you for putting it into the world.


Coyote

A card game by Tim Ferriss and Exploding Kittens

COYOTE is an addictive card game of hilarity, high-fives, and havoc! Learn it in minutes, and each game lasts around 10 minutes.

For ages 10 and up (though I’ve seen six-year olds play) and three or more players, think of it as group rock, paper, scissors with many surprise twists, including the ability to sabotage other players. Viral videos of COYOTE have been watched more than 250 million times, and it’s just getting started.

Unleash your trickster spirit with a game that’s simple to learn, hard to master, and delightfully different every time you play. May the wit and wiles be with you!

Keep exploring.
