The Patience of a Noisy Line

Paul Baran was laughing when he told me about AT&T.

This was before I joined the board of Telebit, his company, a seat I would hold because he later asked me to, which sounds like a credential and was really a gift. At the time we were simply meeting. Before he said a word about the idea the company was built on, he wanted me to know what had happened the first time he tried to explain packet switching to the people who owned the telephone network.

It had happened years earlier, in the early days. They heard him out. They decided it would never amount to anything. He told me the story the way you tell a story about an old friend’s worst haircut, with his whole face, delighted. What amused him was not that they were wrong. It was how complete their confidence was, the particular serenity of people who have never once had to imagine the thing that is about to replace them. Amusement, I would come to understand, was his entire theory of the people who said no.

Then he explained the modem.

The Pioneer

Asa Whitney came home from China with a number in his head, and the number was thirty.

He was a New York dry-goods merchant, born in North Groton, Connecticut, in 1797, and he had made his money in the China trade. He knew what distance cost. The voyage out, in 1842 and 1844, ran the long way, around the Cape or by way of Europe, a hundred to a hundred and fifty days under sail. Somewhere in all that water the arithmetic turned over. Run a railroad to the Pacific, put steam on the far side, and the trip shrinks to about a month. He had seen an early British locomotive in 1830, and now the old impression had a purpose.

He was not an engineer, and the plan shows it. It was simple, almost serene. A line of about 2,160 miles from Lake Michigan to the mouth of the Columbia, somewhere between the 42nd and 45th parallels. Add the roads already built or planned east of the lakes and New York to the Pacific came to roughly 3,000 miles and eight days. He put the cost at $65 million, fifty to build and fifteen to run the road until it could pay its own way, and he admitted the figure was made without a real survey.

The Silence of the Concrete Saint

I was alone in the car when I noticed, which is the wrong way to notice anything.

Something was off about the hillside above the Crystal Springs rest stop. I couldn’t have told you what. It took a mile, maybe more, for the shape of the absence to harden into a fact. The statue was gone.

Twenty-six feet of concrete sprayed over a steel frame. A robed Junípero Serra, kneeling, one arm thrust west toward the missions, set above Interstate 280 in the bicentennial year and left there to watch the Peninsula go by. A thing so large and so constant that the eye had stopped registering it, the way you stop hearing a refrigerator. And then, sometime in the last few months, nothing. A patch of bare earth. No one beside me to ask whether they’d seen it go.

This is what the road does. At highway speed the world beside the freeway is a blur you agree not to examine. The statue stood behind a locked gate, and the people who passed it by the hundred thousand did what the road trains everyone to do. They looked ahead.

It took a walk to catch up with it.

Demons Hate Fresh Air

The notion keeps circling back.

Austin Kleon gave it a clean, memorable shape in Keep Going. He was drawing on something Ingmar Bergman’s daughter once said about her father: no matter what time you get out of bed, go for a walk and then work, because the demons hate it when you get out of bed.

Demons hate fresh air.

There’s a Peanuts strip of Linus out walking that Kleon paired with the line years ago. The image and the words stuck with me. I wrote a short post about it myself more than a year ago, on a clear May morning when the air felt especially clean.

The idea still feels true.

What I’ve been turning over lately is why.

Steven Johnson offers one way into the question in Where Good Ideas Come From. He writes about the many stories of good ideas arriving while people are out walking. The point is not that walking magically manufactures ideas. It is that something happens when we stop trying quite so hard to produce them.

A good idea rarely comes from nowhere. More often, it is an unexpected connection between things that were already somewhere in the mind. A problem, a memory, a half-formed thought, something we read three days ago and forgot we remembered. At the desk, we tend to keep pushing the same thought around the same small circle.

Walking changes the conditions.

The body is occupied, but not very much. Attention loosens. The mind wanders without being completely idle. Things that had been sitting in separate corners begin, occasionally, to find each other.

Darwin had his Sandwalk at Down House, a path he paced almost every day. Poincaré described important insights arriving while he was out walking after periods of intense, fruitless work at his desk. The examples go on.

Apparently, smart people have been wandering around for a very long time.

I notice it on ordinary mornings.

The first part of a walk is usually just clearing the residual static—the night’s dreams, yesterday’s unfinished business, the little collection of thoughts that somehow followed me into the morning. Then, without any particular effort, something loosens.

A sentence that wouldn’t come the night before appears.

A problem that felt stuck suddenly has an edge.

A connection between two things I had never thought to connect quietly presents itself.

None of it feels like work. That may be the important part.

Sometimes the way to think better is to stop trying so hard to think.

The demons prefer the closed room. They thrive on the spinning, the second-guessing, the feeling that the only way forward is more concentrated effort at the same desk.

Fresh air and steady movement are quietly hostile to that atmosphere.

They don’t defeat the demons through force. They simply change the conditions so the demons have less purchase.

And perhaps that’s why the old advice has survived. Get out of bed. Go for a walk. Then get to work.

Not because the walk makes you more productive.

Because sometimes you have to leave the room before you can see the way forward.

Get up. Get out.

The demons can wait.

Inversion

I came across a post on X this morning by Aakash Gupta that cut through the noise around SpaceX’s mobile ambitions with unusual clarity.

SpaceX spent $19.6 billion on spectrum everyone said was too small to matter. 65 MHz—a fraction of what any one of the big three carriers controls. Then Gwynne Shotwell explained where the cell towers go, and AT&T, Verizon, and T-Mobile fell 2 to 4% in an afternoon.

The plan skips towers entirely. Starlink has 12 million customers with dishes bolted to their roofs, and Shotwell wants to attach a small cellular base station to the same mount. Every rooftop becomes a cell site.

That breaks the carrier cost model in a specific way. The radio was always the cheap part of a cell site. The money goes to land leases, permits, and trenching fiber backhaul to feed each antenna, which is why small cell buildouts have crawled for a decade.

Starlink’s version deletes all three. The site is a customer’s roof. The backhaul is the dish sitting next to the base station, already talking to satellites. And instead of paying rent to host the equipment, the host pays SpaceX $120 a month for internet.

Carriers pay landlords to carry their network. SpaceX’s landlords pay SpaceX.

The satellites cover everything the rooftops miss. Next-gen direct-to-cell satellites launch in 2027, and Shotwell says the upgraded service will be 100x better than the version that already texts your phone in dead zones today.

The strangest seat in the room belongs to T-Mobile. They leased SpaceX the 5 MHz that proved direct to cell works, marketed it as T-Satellite, and taught their own customers to trust the signal. In 2027 the partner files in as the fourth carrier.

What struck me most was the inversion itself. We’ve spent decades treating cell towers as fixed, expensive, hard-to-site infrastructure. The real costs were never the radios. They were the land, the permits, the fiber runs, and the ongoing rent checks. SpaceX is proposing to treat the customer’s roof as the site, the existing dish as the backhaul, and the monthly internet bill as the economic relationship—flipping who pays whom.

It is the kind of elegant deletion that looks obvious only after someone points it out. Most industries get stuck defending the expensive pieces of their stack long after those pieces stop being necessary. Here the expensive pieces are simply removed from the equation.

I don’t know yet whether the density will work in dense urban cores, how indoor coverage will actually feel, or how the regulators will treat residential rooftops as licensed transmitters. Those questions remain open. But the cost-model insight feels durable. Once you see that the landlords can be made to pay the network owner instead of the other way around, the old architecture starts to look like a historical artifact.

Worth sitting with for a while.

The Idea That Won’t Let Go

“There are three elements to every great idea: 1. It solves for ‘why.’ Long before you figure out what a product will do, you need to understand why people will want it. The ‘why’ drives the ‘what.’ 2. It solves a problem that a lot of people have in their daily lives. 3. It follows you around. Even after you research and learn about it and try it out and realize how hard it’ll be to get it right, you can’t stop thinking about it.”
— Tony Fadell, Build

The third element is the only one that isn’t optional. You can fake the why — retrofit it, hire a consultant to write it on a slide in a font called Montserrat. You can borrow the what; most products are just other products in a better jacket. You cannot fake the third thing, because the whole test of it is that it happens without your permission.

Call it a visitation. It shows up uninvited at the stoplight, in the shower, at 2:40 a.m. when the ceiling becomes a screen for it. You know the unit economics don’t work. You know the regulatory path is nine years long. You know — you know — that fourteen better-funded people already tried this and left with nothing but a Delaware C-corp and a grudge. None of it helps. The idea has already filed its paperwork. It lives here now.

You cannot bullet-point a visitation. There is no OKR for thinking about landing gear hydraulics while your wife is telling you about her sister’s wedding. Everyone who’s built something that mattered will tell you this, late enough at a dinner and honest enough on the wine: not conviction, not passion — that laminated word — but the visitor, still standing in the doorway of every other thought you’re supposed to be having.

It doesn’t check your calendar. It doesn’t care that you’ve moved on to point two, the sensible one, the one venture capitalists nod along to with their flat whites going warm. It was never about the market. The market is the alibi you build afterward, so you don’t have to say the true thing: I didn’t choose it. It moved in while I was asleep, and my life rearranged itself around the shape of it, the way a house rearranges itself around a family it didn’t ask for.

Maybe the third element isn’t a filter for the idea. Maybe it’s a filter for you — a way of finding out, by accident, at 2:40 in the morning, staring at a ceiling that has decided to keep the light on.

He Taught Us How to See

Michelangelo said he didn’t create his sculptures. He just removed the marble that wasn’t the statue.

I’ve been thinking about that lately. About what it means to have a collaborator whose job isn’t to add things but to help you find what’s already there. I’ve been doing that kind of work recently — the excavation kind — and it has changed how I write and honestly how much I enjoy the making of it.

But I’m getting ahead of myself. Start with Jay.

Test like you fly!

There’s a phrase in the SpaceX documentary that keeps coming back to me: “Test like you fly.” It sounds like a slogan. The kind of thing that gets painted on a factory wall and eventually stops meaning anything. But the more I sit with it, the more I think it’s actually a philosophy that reaches well beyond rocket engineering.

The video — a 25-minute documentary SpaceX released last week — is ostensibly about Starship Version 3. New ship, new booster, new engines, new pad, new test site. Everything rebuilt. And they’re not shy about framing it as a reset, not an upgrade. One description I read called it “a quiet violence in progress.” That phrase stopped me cold, because it’s exactly right. Progress that looks violent from the outside — all that fire and metal — but is somehow quiet in its inevitability.

What moved me watching it wasn’t the engines. It was the engineers. SpaceX put the people on camera: the ones running cryogenic pressure tests at 80 Kelvin, stress-testing tank structures at 70% proof, explaining their failures and their data with the flat affect of people who have made peace with how long hard things take. There’s something almost monastic about it. You choose a problem that will not yield easily. You accept that the work will outlast any individual sprint of enthusiasm. You go back to it anyway.

I keep thinking about that in the context of what we’re doing with AI — the other enormous, fast-moving project that I spend so much of my mental energy on. The development arc is different: iterative releases, weeks not years between jumps, demos that blur into deployment. But the same principle is buried in there somewhere. The best AI teams I read about aren’t the ones shipping the most polished demos. They’re the ones building infrastructure for failure — evals, red-teaming, structured feedback loops. Test like you fly.

The Raptor 3 engines now produce 280 metric tons of thrust each. Thirty-three of them on a Super Heavy booster means over 17 million pounds of liftoff force. I have no intuitive frame for that number. What I do have a frame for is what those numbers represent: three years of iteration on top of five years before that, on top of a theoretical foundation laid by people who didn’t live to see any of this. There’s a compounding in that which I find genuinely moving. Nobody built the Raptor 3 in isolation. It came from everything that broke before it.

The hardest part of the documentary isn’t the engineering. It’s the implicit acknowledgment of how much remains undone. No Starship has yet achieved full orbital velocity with both stages intact. In-space refueling is still untested. The thermal protection systems need more work. And yet — SpaceX talks about unmanned cargo missions to Mars before the end of this year like it’s on the roadmap, not the wish list. That sentence used to sound like marketing. Watching the footage, it doesn’t anymore.

I’m not sure what to do with that feeling exactly. It’s something between awe and vertigo. We’re living in a moment when the audacious has started to have quarterly milestones. When the impossible keeps showing up on timelines and then — bewilderingly, uncomfortably — meeting them.

Test like you fly. Fail with rigor. Build the thing you actually need, not the thing you could more easily explain.

I keep turning that over. There’s a post in there somewhere about writing, too — about the drafts nobody sees, the structural tests that fail, the versions that taught you the one that worked. But that’s for another day.

For now I’m just sitting with the footage of those 33 engines lighting up, and the quiet weight of how much went wrong before they could do that.

The Question Before the Question

I spent hours with Paul Baran over the years, and I never quite got used to his mind.

He asked questions you wouldn’t expect. Not provocative questions, not contrarian ones — just questions that arrived from a slightly different angle than you’d prepared for. And the strange thing was the aftermath. You’d hear the question, feel briefly disoriented, and then — almost immediately — think: of course. Now I understand.

Paul invented the Telebit Trailblazer modem. If you were around in that era you remember what modems were: devices that negotiated a fixed speed and held it. The whole industry operated that way. Speed was a spec, a number on the box, a ceiling you bumped against.

Paul looked at the same problem and saw something different. He didn’t ask how fast a modem could go. He asked what a specific telephone circuit was actually capable of — this wire, right now, in these conditions. The Trailblazer was adaptive. It listened to the line before it decided anything. It milked transfer speeds out of circuits that conventional modems had already given up on.

That’s not a new technique. That’s a new question.

I’ve thought about Paul a lot since then, trying to locate the thing that made his mind work differently. I don’t have a single moment to point to. No whiteboard revelation, no conversation I can replay. Just the accumulated residue of hours in the room with someone who seemed to be operating on different premises than everyone else — asking the question that preceded the question the rest of us were answering.

Morgan Housel quotes Visa founder Dee Hock in Same As Ever: “New ways of looking at things create much greater innovation than new ways of doing them.”

I read that and thought of Paul immediately. What I took from all those hours with him wasn’t a method or a framework. It was simpler and harder than that — a habit of suspicion toward the assumptions already in the room. The ones everyone had agreed to without quite deciding to. The fixed speeds no one was questioning.

I still hear his voice when I catch myself accepting an assumption. Is it, though?

We Are All Painters Now: The Era of Vibe Coding

For decades, the act of creating software was exactly that: writing. It was a distinctly left-brained, agonizingly precise discipline.

Programmers were typists of logic, translating human intent into a rigid, unforgiving syntax that a machine could understand. A single misplaced semicolon, an unclosed bracket, or a misspelled variable could bring an entire system crashing down.

Building software meant placing one brick after another, working meticulously from the ground up.

In this traditional paradigm, coders were the ultimate embodiment of Annie Dillard’s writer. As she noted in The Writing Life, “Writers… work from left to right. The discardable chapters are on the left.”

When you wrote code, your mistakes, your refactoring, and your discarded logic were all part of a linear, grueling journey. If a feature didn’t work, you had to physically wade back into the text, debugging, reading line by line, and rewriting the narrative of the application. The discarded chapters were the endless hours spent wrestling with a single broken dependency.

But recently, a profound paradigm shift has quietly taken over our screens. We are transitioning out of the era of writing software and into the era of “vibe coding.”

Vibe coding fundamentally changes our relationship with the machine. With the rise of advanced AI coding assistants, we are no longer placing the bricks ourselves; we have become the architects and the creative directors. You don’t write the loop or manually construct the database query. Instead, you describe the feeling, the function, and the outcome. You tell the AI, “Make this dashboard feel more modern,” or “The logic here is too clunky, make it flow faster and handle edge cases gracefully.” You are coding by intuition. You are steering by the “vibe” of the output rather than the mechanics of the input.

Suddenly, Dillard’s other metaphor takes center stage. In the age of vibe coding, we have become painters.

“A painting covers its tracks. Painters work from the ground up. The latest version of a painting overlays earlier versions, and obliterates them.”

When we vibe code, we ask an AI for a functional prototype, and it gives us a canvas. We look at it, test it, and sense whether it aligns with our vision. If it doesn’t quite hit the mark, we don’t necessarily rewrite the code from scratch. We simply prompt the AI to try again, adding a new layer of instruction. The AI paints a new layer of code directly over the old one. The awkward, underlying iterations—the messy attempts at styling, the inefficient logic of the first draft—are obliterated by the newest prompt.

The machine covers our tracks for us. We don’t need to know exactly how the underlying pixels were rearranged or how the syntax was refactored. The final application emerges as a stunning obliteration of its own clumsy past.

As someone who has spent time wrestling with the rigid demands of syntax, there is a strange, quiet grief in letting go of that left-to-right process. There is a deeply earned, tactile satisfaction in building something manually, understanding the precise weight and placement of every line of code. Relinquishing that control can feel like a loss of craftsmanship.

Yet, there is also a breathtaking liberation in this new medium. We are moving from a world of manual construction to a world of artistic curation. The barrier to entry is no longer fluency in a specific, arcane language; it is simply the clarity of your imagination and your ability to articulate your intent.

The next time you sit down to build something digital, notice the shift in your own posture. You no longer have to carry the heavy burden of the writer, agonizing over every word and leaving your discardable chapters on the left. You can step back, look at the whole canvas, and trust your intuition. Let the AI cover the tracks. Embrace the obliteration of the early drafts.

We are all painters now, coaxing the future into existence one brushstroke at a time.
