Core Memory

Our guests this week are Andrew Kiguel and Matt McMullen from Realbotix.
Realbotix makes humanoid robots that actually look like humans. McMullen, who founded the company, has spent years refining the animatronics and materials needed to create lifelike machines. His past creations have received tons of media attention both because they’re striking and because they veer into companionship and sex territory.
Lars and the Real Girl? Yep, that’s Matt’s work.
Realbotix, though, is an attempt to take the technology in a different direction. The company has made AI-infused bots that it wants to put to work out in the world. The bots could greet guests at hotels, provide information at hospitals or perhaps tutor students at schools. The Realbotix bots can carry on conversations and use vision systems to recognize people and take in their surroundings.
We conducted this interview in Las Vegas where Realbotix has its headquarters. In a future video on our YouTube channel, which is awesome and you should subscribe to, I head out into Vegas with a bot named Aria, and we have a delightful afternoon together.
Some of you will think these robots are weird. And I get this.
I will, however, add that most of the humanoids out there are very boring. Companies have focused on what the robots can do rather than what they look like. The folks at Realbotix, by contrast, have put a lot of time and energy into trying to figure out how humans and robots will interact and progress together. We get into all of this on the show.

Some of you will be wondering, “Is this episode sponsored?”. Yeah, it is. By the wonderful people at Brex.
I’ve worked at large companies like The New York Times and Bloomberg, and their expense systems were terrible. Brex’s expense management systems, by contrast, are fantastic. AI agents run around taking care of tons of stuff for you and give you back your time.

This week’s guest is Brent Underwood, the proud owner of Cerro Gordo Mines.
That’s right. In 2018, Underwood bought the ghost town of Cerro Gordo, located near Death Valley in California, and its old mining operations for $1.4 million. This was a legit crazy thing to do. But, here we are eight years later, and Underwood has turned his sidequest into his mainquest, and he now has a booming YouTube channel in which he documents life at Cerro Gordo. This includes exploration of the mines and Underwood’s attempt to restore the ghost town into a habitable site that people can visit.
You will notice (if you’re viewing instead of just listening) that the set for this podcast is awesome. That’s because we went to visit Underwood a couple of months back for this podcast and for a video that will be coming out on our own booming YouTube channel.
We spent a couple of nights at Cerro Gordo, living in an old miner’s house, and we explored the grounds with Underwood.
As you’ll hear in this episode, Cerro Gordo was a long-running silver mine and, at its peak, had 4,000 people living in the mountains and working the many miles of mines. It’s quite well preserved. You can see the old brothel, theater, and store. And Underwood has been rebuilding the American Hotel that once served as the centerpiece of the town.
Underwood does crazy things at Cerro Gordo. He’ll lower himself down the main mine shaft and then spend days underground. He’s used his exploring to help build out the history of Cerro Gordo and wrote an amazing book about Cerro Gordo and his adventures. You should probably buy it and read it.
We obviously get into all of the above with Underwood, who is a wonderful storyteller and a good dude.

A few years ago, some people put me in a van and drove me to the edge of Moscow. And by “the edge of Moscow,” I mean where things started to get a bit rural. We turned off a road and went toward what looked like a modest farmhouse with a shed. After exiting the van, we entered said shed and found two large metal containers that were full of human bodies and heads along with the bodies of many animals, including dogs, cats, and a hummingbird. Have a look.
These bodies were being cryopreserved with liquid nitrogen in the hope that they could be reanimated at some point in the future when science has advanced and more illnesses can be cured.
Cryopreservation/reanimation is not a new idea. It’s been contemplated in literature for hundreds of years. Alcor, perhaps the most well-known cryopreservation company, was founded way back in 1972. The field, though, has suffered from questionable science and been seen as a scientific backwater.
Our guest this week wants to add scientific, intellectual, and pragmatic rigor to the cryopreservation field or what he calls the biostasis field. He’s Dr. Emil Kendziorra, the founder and CEO of Tomorrow Bio.
Tomorrow Bio has a team that will show up at the end of life and prepare someone’s body for preservation and then store their body in a Swiss vault.
In this episode, we get into the mechanics behind Tomorrow Bio and the pros and cons of biostasis. Kendziorra is a sober, deep thinker on this topic and a great listen.

We’ve heard a lot of moonshot ideas on this podcast, but this week’s guest may have the most impossible one yet: making tech more cultured.
In this episode, Ashlee sat down with Anna Gát, a Hungarian philosopher, playwright, and founder of Interintellect, a platform for hosting intellectual conversations online. She calls herself “the bridge” between the humanities, academia, and the tech world, which in practice means getting engineers to read Goethe.
Gát grew up on a TV set in communist Hungary. Her parents made the country’s biggest shows in an era when there was one channel available on Saturdays. In 2015, a family crisis left her starting over in London with two suitcases, one of them for books. She rebuilt her life on Twitter, DM’d Sam Altman, and got him as her first meeting on her first trip to America.
Before Interintellect, Gát did just about every wordcel job you can do: playwright, screenwriter, script doctor. She holds graduate degrees in philosophical aesthetics and linguistics, currently splits her time between SF and NYC. The company that would become Interintellect began in London in 2016 as an AI tool for helping “humans have categorically better conversations.” On the side, she angel invests in aerospace.
The two get into why X was once the French café that could publish you and is now a place you can’t get discovered from, why the East Coast’s healthiest, wealthiest people are so convinced the future is doomed, and the duty AI builders have to explain themselves. Gát also admits, on the record, that she’s a sucker for Elon Musk’s syntax. Ashlee tries to convince her that kids don’t read books anymore. She tries to convince him Silicon Valley should fund symphonies.

In this episode, Ashlee sits down with Joel Jean, CEO of Swift Solar, a San Carlos-based startup trying to create new solar technology using perovskite. We previously published a story about Swift, if you’re wondering what the f*ck perovskite is! In short, it’s a synthetic crystal that turns sunlight into electricity better and cheaper than the silicon currently used in solar panels. This stuff is finicky though, and experts have doubts, as they always do — but Jean explains how Swift is closing in on a solution.
“Everyone and their mom can make a perovskite that’s decently efficient,” Jean says, but no one seems capable of making it as durable as silicon. The material degrades under heat, light and its own moving ions. This is obviously not the ideal situation for an energy grid.
So why not stick with silicon? Well, the laws of physics haven’t quite blessed it. A silicon panel can turn, at most, about 30 percent of the sunlight it gets into electricity, and today’s panels usually churn out about 25 percent. If they’re able to successfully layer perovskite on top, that pushes the ceiling to 45 percent.
These are fabulous gains in the solar nerd world, and we could really use some innovation here because we are one very, very energy-hungry species. And of course, this is Core Memory, so you know where this is headed: China and AI.
China makes 90 percent of the world’s solar cells and wafers, installs more panels than the rest of the planet combined, and builds the machines that nearly every U.S. solar factory runs on. (Except for Swift, apparently!). That dependency is, as always, a risk.
Meanwhile, AI data centers need more power than God, and the folks making models are happy to welcome any new gains in that department. Some are even putting their money on it; renowned AI researcher Jeff Dean has invested Swift.
Charge your crystals, folks. We’re perovskite-maxxing.
