Most people think that the Red Bull guy Felix Baumgartner holds the skydiving record. But this is not the case.
The real record-holder is Alan Eustace. In 2014, at age 58, the Google engineer rode a helium-filled balloon into the stratosphere and then fell back to Earth from 135,890 feet. Eustace’s fall lasted 4 minutes and 27 seconds, and he broke the sound barrier, reaching a max speed of 822 mph. And now, in a very rare appearance, Eustace has come on the podcast to discuss his adventure.
Baumgartner, who dropped from 128,852 feet, received tons of attention because Red Bull turned his jump into a media spectacle. Eustace, by contrast, came up with the plan for his jump and spacesuit at his kitchen table, paid for a small team to help him build his suit and then did his skydive with just a single reporter there as a witness.
This all fits with Eustace’s personality. He’s quite private and just goes about his work.
It took several months of begging to get Eustace on the show, and I don’t think he’s ever discussed his skydive in this type of detail before.
In this episode, we get into what drove a 58-year-old man to want to chase this feat, the rich history of stratosphere jumping and Eustace’s remarkable career as one of the key Google engineers who built the modern internet. We also hear Eustace’s thoughts on AI and his latest quest to search the ocean floor.
(I apologize for saying that Eustace jumped from space in the episode. It was the stratosphere. I was excited.)

Treating cancer remains a crude practice. We cut, burn and poison tumors, and we do all this with relatively little precision around both the initial treatment and our ongoing monitoring of how effective the treatment is. You show up for scans now and again and hope that whatever you’ve been doing has been working.
Ben Woodington - who is an absolute unit - and the team at Coherence have come up with a new way to monitor and treat tumors. They’ve built an implant that, as the name suggests, gets placed inside the body to keep a constant watch on a tumor’s behavior. The chip also brings with it the ability to deliver electrical signals that may blunt a tumor’s growth. We’re talking constant monitoring of a tumor to see if treatments are working and the ability to read and write electrical signals as part of a totally novel bio-tech device.
In this episode, Ben explains how this technology works and, more broadly, he walks us through the emerging field of neuro-oncology or cancer neuroscience. We have a look at Coherence’s device, which is reminiscent of Neuralink’s implant, and rival technology.
Since we recorded this episode, Coherence has begun a study in Australia where its device is being used to record and stimulate brain activity in patients having brain tumors removed. The company has also put out a paper detailing some of its work and has brought on Neuralink’s neurosurgery lead Matthew MacDougall as an advisor and investor.
This episode was a treat for me because I had no idea this type of technology even existed, and because Coherence seems to have made a remarkable amount of progress on its hardware in a short time.

Running a media business is hard. You’re competing for people’s attention. You must produce a relentless stream of new things that are good and different. And you’re often dependent on the ever-changing whims of the public and advertisers.
John Coogan and Jordi Hays somehow made all of this look easy when they started TBPN in late 2024. The daily tech ne…

Prineha Narang is one of the rising stars of science and the field of quantum technology.
She earned her PhD in applied physics at Caltech, taught materials science at Harvard and now has her own lab at UCLA. The lab focuses on quantum materials, non-equilibrium dynamics, photonics, quantum information science and other easily digestible areas. Beyond her academic career, Narang is a science advisor to the government and a venture capitalist at DCVC.
As you might imagine, we get into quantum computing and quantum technology in this episode. Quantum vs. AI, the US vs. China, when quantum tech will break encryption, quantum sensing and whether or not quantum technology actually has a bright future. The quantum sensing portion of the chat was all new to me and rather astonishing.
Since Narang is also a competitive runner and mountaineer, we provide some top tips on gear because that is just the kind of all-purpose podcast that we deliver.
And, if you can’t get enough quantum computing, come check out our video episode on PsiQuantum building the largest quantum machine in history.
Enjoy!

A few years ago, I was lunching with a young Australian man who told me he hoped to modernize manufacturing in America. This man seemed enthusiastic and ambitious, but I must confess to holding some serious doubts about the dramatic scope of his plans and his ability to pull them off.
This man was Chris Power, and, well, he did the thing. He’s the founder and CEO of Hadrian, which has a growing empire of mega factories packed full of machines that cut, bend and weld metal. Hadrian has become a workhorse for defense and aerospace and other big industries. It has used software to make it easier for people to control many machines at once and to keep track of the manufacturing process in a bid to add more quality control to industry.
Power has become one of the main players in the Reindustrialization movement and one of its more direct and critical voices.
We did this interview at Hadrian’s headquarters in Los Angeles with factories humming behind us, and we’ll have a video with all the machines soon on our YouTube channel. Chris and I get into his history, Hadrian’s history and the state of American manufacturing.
