Headlines | OpenAI Devices, Data Centers, Brightline

This month's headlines open with manufacturing in the US falling short of expectations. Jon and Alex unpack a Bloomberg investigation into a $1 billion federal push to build medical gloves domestically that has, five years on, produced zero gloves. Reshoring continues to be easier said than done. From there they turn to Fairlife, the Coca-Cola-owned dairy brand that grew sales from $10 million to $4 billion in a decade and just had its US production halted by a ransomware attack, the latest in a run of hacks targeting food and auto manufacturers. Jon and Alex dig into two recent columns on China's fast-closing AI gap, then cover Bloomberg's reporting on OpenAI's first hardware product, a screen-free AI companion built to move around the house, and the $230 Codex Micro keypad it shipped first. From there, they look at why transformers, largely unchanged since the 19th century, have become the surprise bottleneck constraining AI data center buildouts, and debate whether GPU energy use is actually the problem critics say it is. They close with a deep dive into Brightline, the private Florida railroad dubbed a “Killer Train” for its poor safety record.

StockX COO Stephen Winn on how the marketplace verifies products, catches counterfeit sneakers and AirPods, and why CT scanning is the hardest check to fake.

Stephen Winn is Chief Operating Officer of StockX, the online marketplace where every single product sold passes through a verification process before reaching the buyer. He was employee number six, wrote much of the original platform code, and now oversees an operation spanning 170 countries, 5,000 trade lanes, and 71 million lifetime sales. We recorded this episode inside the company's Detroit verification center, where specialists scrutinize everything from shoes to electronics day in and day out. Stephen walks Jon through the full defense-in-depth verification stack: machine learning risk scoring that runs before a package even arrives, RFID checks against chips embedded by brands like Nike and Adidas, trained verification experts who inspect stitching and packaging and even the smell of products, and a Lumafield CT scanner used on every product over $3,000. Since 2016 that process has stopped $750 million in products that failed to meet StockX's standards, including over $100 million in suspected counterfeit footwear. Winn explains why counterfeiters focus on what buyers can see and why internal structure remains the hardest thing to fake, recounts the CT scan that revealed Nike had hidden a numbered edition marking under the tongue of the Wizard of Oz Dunks, and closes with the go/no-go decision behind the patented all-in ask that keeps StockX a single global marketplace.

Midjourney's medical scanner, a Patriot missile's two-year supply chain, and why Ford had to rehire 350 engineers it let automated systems replace

This month, manufacturing headlines ran the gamut. Midjourney, the AI image generator, has entered the scanner business. Jon and Alex unpack the Midjourney Scanner, a full-body ultrasound device the company is positioning as a wellness habit rather than a diagnostic tool, and why the medical community is wary of preemptive scanning. Dexcom traces a sensor theft back to an unauthorized distributor, and the Wall Street Journal explains why a Patriot missile takes two years and 400 suppliers to build. They also cover stalled subsea cable projects across the Gulf, Snap's $2,195 Specs glasses, a New York Times guide to buying used electronics, and China's bet on humanoid robots to offset a shrinking workforce. The episode closes on Ford, which just hit number one in JD Power's quality rankings after rehiring 350 engineers it had automated away.

Federico Faggin designed the first microprocessor and the capacitive touchscreen. He joins Go/No-Go to argue that AI cannot be conscious, however capable it becomes.

Federico Faggin designed the first microprocessor. The Intel 4004 was the chip that first made it possible to put an entire programmable computer on a single piece of silicon. The process technology he developed at Fairchild Semiconductor became the foundation for every microprocessor, memory chip, and logic device built in the half-century since. The touchscreen on your phone exists because of work he went on to do at Synaptics in the 1990s, when his team replaced the trackball with capacitive touch. In between, he spent years in the 1980s building hardware for neural networks at a moment when the AI research establishment considered the whole idea a dead end. History has proven him right. Faggin joined Jon to recount the physical reality of early chip design, from drawing transistors by hand at 500 times scale to sizing circuits with a slide rule and building the Z80 with 11 people and $400,000. Decades of working at the vanguard of silicon technology led him to confront the ultimate capabilities of computers. That question has consumed the second half of his career. He has written a book, Irreducible (2024), arguing that consciousness is not something a classical computer can produce, no matter what it seems able to accomplish, and he cautions against allowing AI enthusiasm to make us forget what makes us human in the first place.

Iran war bitumen shortage stalls roads, Ford's $30K electric truck, Tesla Semi ships, BYD's private fleet, Amazon logistics, and the real cost of quality.

The war with Iran keeps reshaping manufacturing in unexpected places. A bitumen shortage tied to the oil disruption is stalling road construction from India to Italy, and ships stuck in the Gulf are accumulating barnacles and jellyfish that foul their hulls and raise fuel costs. We trace that thread through a packed automotive segment: Ford's secret skunk works racing to build a $30,000 electric truck, the Tesla Semi finally shipping at $290,000 with 300 miles of charge in 30 minutes, and BYD's fleet of eight company-owned car carriers that ferry 300,000 vehicles a year through waters other ships avoid. Amazon is opening its logistics network as a third-party service, and the Trump Mobile phone shipped nine months late looking a lot like an HTC handset from Taiwan. Then we sit down with Alex's new Cost of Quality report, built on a survey of 210 quality decision makers, on what quality actually costs and why most manufacturers can't measure it.

Paradromics CEO Matt Angle on building the highest data rate brain-computer interface, hermetic sealing vs. Neuralink, and what makes BCIs last a decade in the body.

Matt Angle is the CEO of Paradromics, a neurotechnology company building high data rate implantable brain-computer interfaces for people who have lost the ability to speak and move. The company's Connexus system, currently entering clinical trials, clocks an information transfer rate of over 200 bits per second (more than 20x the reported performance of comparable systems) and is designed to last more than a decade in the body. The conversation covers the basic physics of what separates an implanted electrode array from a surface EEG, the design of the Connexus itself, and the engineering choices that distinguish Paradromics from Neuralink: hermetic sealing, modular battery placement, and a deliberate bet on durability over planned obsolescence. We also get into what it takes to manufacture a device at the micro scale, where CT scanning fits into quality control once you've welded a titanium case shut, and the formative go/no-go moment when the team bet their company on a DARPA contract against consortium bids from Berkeley, Harvard, Stanford, and UCSF.

Allbirds collapses, SpaceX IPO targets $1 trillion, Iran buys a Chinese spy satellite, Sony Honda AFEELA canceled, Slate raises $650M, lab-grown chocolate.

Allbirds sold its name and assets for $39 million after a $4 billion IPO in 2021, and the shell listing is now being used to raise $50 million for a GPU-as-a-Service company called NewBird AI. We use it as a window into the D2C brand era and what it takes to build a consumer brand that lasts. SpaceX filed confidentially for a June IPO targeting $50 to $75 billion at a self-assessed valuation over $1 trillion, with Starlink generating $11.4 billion of that revenue in 2025. Iran acquired a Chinese spy satellite with half-meter resolution for $36.6 million through an in-orbit delivery model designed to sidestep export restrictions. A Citrini Research analyst rode a speedboat through the Strait of Hormuz to find out whether the blockade is real. On the automotive side: the Sony Honda AFEELA is canceled before release, Honda expects a $15 billion loss and its first unprofitable year since 1957, Slate raised $650 million for a bare-bones $25,000 EV pickup, and Stellantis is recalling 700,000 vehicles over a fire risk. We also cover lab-grown chocolate and why cocoa went from $3,000 to $12,000 a ton.

The Takata airbag recall: how a propellant chemistry decision in the 1990s became the largest and costliest automotive recall in history, and why it still isn't over

We open with a Takata airbag sitting on the desk in front of us: a unit manufactured at the Monclova, Mexico plant at the center of the recall disaster, purchased on eBay and arrived by UPS ground. We couldn't determine whether it's one of the recalled units. The Takata airbag recall is the largest and costliest in automotive history, spanning just about every major automaker and now approaching 30 US deaths. We reconstruct the engineering story: how ammonium nitrate became the propellant of choice over cheaper and less stable alternatives, how its crystalline structure degrades through heat cycles and humidity over time, and how that degradation turns a supplementary restraint system into shrapnel. We also CT scanned the airbag, and we walk through what the scan reveals about how these assemblies are constructed. The organizational story runs alongside the engineering one: falsified test data, a 50-year Honda-Takata supplier relationship that led to complacency instead of accountability, a regulatory revolving door, and a whistleblower who spent years trying to prove that recalled airbags were being shipped as non-hazardous freight. The recall completion rate is now at 98%, a remarkable figure. The remaining 2% represents over a million vehicles still on the road, and the units that haven't been replaced are the oldest and most degraded.

Nick Terzulli of Fellow on inventing Espresso Series One, why home espresso has stagnated for decades, and the physics of heating water on 120V.

Nick Terzulli is Vice President of Research and Development at Fellow, the San Francisco coffee equipment company whose products can be found everywhere from Target shelves to your favorite third-wave coffee shop. Before Fellow, Nick worked on military robotics and designed medical devices at Stryker and Dextera, before spending several years scrubbing toilets at a coffee shop for $10 an hour just to learn how to make coffee using the best equipment available. The central problem Terzulli came to Fellow to solve has constrained home espresso since the beginning: 120V household power limits thermal and pressure stability in ways that commercial machines, running on much higher amperage, simply don't face. The best home machines either take 40 minutes to heat up or sacrifice performance to achieve fast heat-up times. Terzulli's answer, which became Fellow’s Espresso Series One, uses three separate heating elements staged in sequence to achieve commercial-level stability with a two-minute heat-up time, a novel approach he holds the sole utility patent on. The conversation covers how that architecture came together, what it takes to design for both the beginner and the specialist, how Fellow uses firmware and over-the-air updates to build community around its machines, and why designing coffee burrs from scratch was, in his view, the hardest technical challenge of his career.

Iranian cyberattacks hit medical device supply chains, the Pentagon orders 3,000 Skydio drones in 72 hours, a blood-filtering fraud earns federal charges, and plug-in hybrid owners almost never plug in.

The conflict with Iran has reached U.S. supply chains: an Iranian-linked cyberattack wiped devices across Stryker's global operations overnight, cutting the medical device company off from the hospitals it serves. We also cover the Pentagon's 3,000-drone Skydio order completed in 72 hours, California gas at $5.89 per gallon, a Fraunhofer Institute study finding that plug-in hybrid owners mostly don't plug in, criminal charges against a former ExThera Medical executive for concealing patient deaths from the FDA, Cargill's computer vision system that found $200 million in beef without adding a single cow, the OmniPod 5 recall, and iFixit's MacBook Neo teardown.
