Lost my phone at the office and spent 30 minutes turning the place over. Find My was disabled by MDM.
Out of ideas, I asked Claude how I could find it. It suggested tracking the Bluetooth signal strength, then wrote me a meter in about a minute.
I walked around watching the number climb. Found it.
Apparently you can just make the tool you need now.

You wake up
Your husband looks young, the same mustache he used to have over twenty years ago
There are voices in the kitchen
You sit and listen, you can make out one, two… three, three little voices all the way in the kitchen
There is the smell of pancakes in the air, along with some bacon, you are hungry
You look down, your hands, so young
As soon as you walk into the kitchen little voices all cry out your name “mama, mama!!” Hugs filled the air along with sticky syrup hands, but you do not care
By the sink there he stands, your husband
Tall, full head of blonde hair, and you cannot help but hug him. His body feels so strong, filled with youth, you take his smell in, and you stand there taking in the warmth, listening to the children arguing over who gets the last piece of bacon, watching their little feet run across the kitchen floor, memorizing everything, because this ordinary so unimportant Saturday is what you wish you could go back to the most
And then you wake up, life has gone by, you are old, the house is empty, the children are grown, your body aches
And you finally know, you finally understand that at the end of life you will not wish to have had more promotions, to have gone back for one more day of work, to of had more time to clean the house, for one more day of school, for errands, for anything else besides a slow Saturday morning where the air smells like pancakes, and the house is filled with little voices, and you are woken up to the small bodies and the smell of the little heads you love most in the entire world.
An extraordinary life is made up of ordinary days. Of a summer breeze, and small hands, of cold cheeks you kiss in the autumn afternoons, of a steady hand that holds yours, of the wonderful miracle that is having everyone you love, all with you under the same roof.

An American invited me to his house.
I asked what I should bring.
He said, "Nothing, man."
Nothing. I brought nothing. This was a catastrophe.
Every other guest brought something. Not gifts. Provisions. A woman brought a bag of ice. A man brought a folding chair. Someone brought paper towels, which is not a gift, which is infrastructure.
They had all been told nothing. They all brought something. Nothing means something. Nothing has always meant something.
Inside I said: THE HOST SPOKE FALSELY AND EVERY GUEST UNDERSTOOD, AND NOT ONE OF THEM CORRECTED HIM, AND THE SYSTEM HELD.
Then I learned about the second beer.
A man handed me a beer from a cooler. Not the host. A guest.
He was distributing beers that he had not purchased, from a cooler he did not own, to people he had not met. He had appointed himself. Nobody appointed him. He was simply nearest the ice.
Inside I said: HE HAS SEIZED THE SUPPLY LINE. IT WAS UNDEFENDED AND HE TOOK IT AND NO ONE HAS OBJECTED.
I drank the beer.
When I finished it, the same man appeared at my elbow with a second one, already open.
I had not asked. I had not signaled. He had been monitoring.
Somewhere in that backyard a man was tracking the fluid levels of eleven strangers and adjusting supply in real time and drinking while he did it.
I asked him if he was related to the host.
He said, "We work together."
Then he said, "Not anymore. He quit."
He does not work with the host. He came anyway. He is managing the cooler at the house of a man he no longer sees daily.
I asked when the host quit.
"Two years ago."
Two years. He has been coming to this house and running the cooler for two years past the expiration of their professional relationship.
Inside I said: THE ALLIANCE OUTLIVED THE WAR. THIS DOES NOT HAPPEN. IN MY COUNTRY THIS DOES NOT HAPPEN.
At the end of the night I moved toward the cooler to help clean up.
He stopped me.
He said, "I got it."
Then he said, "You're a guest."
Then, on my way out, he said, "Next time bring nothing again. It's funnier now."
He remembered. Four hours ago I had arrived empty-handed and he had noticed and said nothing and now he was making it mine.
I have been back four times.
I bring nothing. Every time.
It is now a bit. There is a running joke about it. Two people who were not there the first night have been told about it.
I have a bit.
I did not earn it. I was given it by a man who does not work there anymore.

Memory Liquidation
The AI memory market is not the telecom boom, and it is not the housing bubble.
What we are seeing now is a leverage event: too much leverage, too much crowding, and too much exposure piled into the same trade, all of which now need to be unwound. That matters because a real supply crunch in memory has been amplified by positioning, acute shortages and sharply higher prices tied to AI infrastructure demand are real.
Yes the easy money in the AI trade has been made!
Let’s be explicit about what that means. Parabolic charts are not proof of durable fundamentals; they are often evidence of momentum, leverage, and borrowed conviction feeding on themselves. When a trade gets this crowded, price stops reflecting only supply and demand and starts reflecting how much fast money is trapped in the move.
The underlying AI demand story is still real, and the fundamental supply-demand imbalance still exists. AI demand has forced companies to fight for dwindling memory supplies, while chipmakers prioritized higher-margin data-center chips and memory prices spiked sharply over the past year.
But that does not mean every price swing is fundamental. Narrative follows price: when memory names surge, investors discover scarcity; when they break, they suddenly discover China risk or efficiency gains.
That is why the analogies to the 1990s telecom boom and the housing bubble are only partly useful. In those episodes, supply ran ahead of demand, too much fiber, too many houses. Here, demand has outrun supply, but the stock market layered excessive leverage on top of a real bottleneck.
As Graham observed, the market is a voting machine in the short term and a weighing machine in the long run. Right now, the vote is being driven by crowding, leverage, and forced selling.
Over time, the market will weigh the underlying AI demand and the still-tight supply picture on their merits. What is being liquidated is not the existence of demand. It is the leverage wrapped around the story.
Yes Parabolic charts that amplify crowded leverage one way bets should be avoided.

Every single cycle there are always signs. Hindsight is clearly 20/20 but always fun to look back.
1. Leopold being peddled as a celebrity, and every stock he mentioned or bought got bid up
2. Jensen calling $MRVL the "next trillion-dollar company," sending the stock up 32% in a single day
3. The Pattern Day Trader (PDT) rule getting removed. Since it was scrapped on June 4th, that practically marked the top on $MEME, down ~44% since
4. An anonymous "bottleneck" investor focusing on key chokepoints goes to nearly 1 million followers on X, pumping random foreign stocks hundreds of percent
5. Terry Smith capitulating on his strategy and incorporating "momentum"
6. Record use of margin and leverage by the Koreans. Total casino over there
7. Margin debt as % of M2 at its 2nd highest level in history, just behind the dot-com bubble
8. Newly minted "memory experts" finding $SNDK and turning bullish after a +2,000%+ 1-year run
9. $SPCX IPO
10. Elon Musk becoming the world's first trillionaire on June 12, 2026
11. 5 sigma deviation for momentum stocks vs. low volatility
12. $SOXX $SMH "June 2026 marked the largest aggregate month of inflows into semiconductor ETFs, exceeding $19 billion."
Sentiment is fascinating to me. So much value in being aware of the narratives, what's going on beneath the surface, etc.
Always fun to go back and see how obvious it looks in hindsight, but not in the moment.
Purely for fun compiling this, but every cycle you start to sniff the froth out a little better.
What am I missing? Anyone got signs to add?

Hinge is a dating platform for the cosmopolitan-aspiring chungus. For the upwardly mobile sex-seeker who wishes to highlight their personal brand. The app feels like a lifestyle deck prepared for prospective romantic investors. Networking-event dating. Airport-lounge seduction. McKinsey erotica. Podcast BDSM.
I used it while living in NYC and it seemed optimized for women who post boss-bitch brunch on Instagram and Patagonia-vest men who post “thought leadership” on LinkedIn. The profiles are tastefully androgynous with a strategically casual photo in Lisbon and a personality assembled from premium consumer subscriptions. Authenticity that photographs well.
High likelihood Hinge users have a therapist and/or a breathwork instructor, do “Friendsgiving”, are a “foodie”, “fluent in sarcasm”, and call their BF/GF their “partner” (please die).
The profiles communicate: I’m professionally presentable, politically house-trained, sexually adventurous within administratively approved parameters, and willing to travel somewhere photogenic 3-4 times/year. It says “I’m equally happy at a dive bar or a Michelin restaurant” while being visibly unhappy at the dive bar. The types who carry around hand sanitizer.
Hinge has the energy of a white man wearing a gold chain over a knit polo: every detail is plausible, yet the total composition feels… off.

As someone who has personally spent $500k / mo+ on Google Ads for years, I can tell you with certainty:
This revenue growth in Search is artificial & extremely unhealthy for Google’s business long term
Search volumes are declining as legacy search is being increasingly cannibalized by non-monetized LLM queries
Google’s response?
Manufacture revenue growth via short-sighted, highly extractive, customer-hostile tactics. I.e. charge advertisers more for lower quality clicks, including clicks they do not want and explicitly did not approve Google to charge them for
A few examples to illustrate:
For all of its history until recently, Google operated on a 2nd price auction model
I.e. if you bid $5 CPC and the next highest bidder bids $1 CPC, Google charged you $1.01 for the click (one penny more than the 2nd highest bidder) rather than the $5 you bid
This was a genius move by Google early on as it incentivizes advertisers to input their true maximum willingness to pay rather than trying to play the game of bidding low and constantly adjusting to try to stay just ahead of the next highest bidder while still not paying too much
However recently, Google silently deprecated the 2nd price auction and began charging advertisers as much as their bid and budget caps allow, regardless of what anyone else is bidding
It’s a short-sighted cash grab at the expense of the long term health of the advertiser ecosystem
Making thing worse, Google also recently nerfed keyword targeting precision
Google previously had precise keyword targeting settings that allowed advertisers pick individual search phrases to bid on, defined down to the character w/ exact match or phrase match targeting
This was one of the core features that made search advertising magic, enabling advertisers to run extremely precise campaigns based on exactly what their target customer typed
But now, even if you bid on a specific term or phrase using the strictest exact
-match targeting settings, Google will show your ad across 1000’s of unrelated keywords, labeling them as as “exact match (close variant)”
The definition of “close variant” means whatever they want it to and changes constantly. The result is advertisers get billed for clicks that are totally irrelevant to their business and that their targeting settings explicitly forbid Google from targeting. Google does it anyway and there’s no ability to turn this off
So now exact match is broad match, and broad match is just meaningless spam
This is all very bad for advertisers, but for Google, it allows them to show your ad and bill you for clicks across 1000x more searches that were previously going unmonetized (mainly because they’re garbage queries no one wants)
This is how you grow revenue atop declining search volumes
Lastly, and perhaps most egregiously, Google quietly stopped respecting budget caps by a factor of 2x. For example campaigns we’ve been running for years with $1000 daily budget caps suddenly began spending $2000+ per day
And the extra spend is entirely on the garbage keywords Google arbitrarily throws in as “exact match (close variants)” which have no value to our business, but can’t be turned off
Google offers no refunds nor any recourse for overspend or spend on keywords you explicitly did not target
These are not the actions of a healthy business. These are the actions of company whose core business is in decline but desperately needs to pump quarterly earnings so Wall Street will continue to fund insane capex while hopefully looking through their rapidly deteriorating negative free cash flow
Google operated a benevolent monopoly for the better part of 25 yrs
Meaning the value Google captured from Search was but a small fraction of the value it created, and that spread produced a potential energy that justified expectations of high earnings growth far, far into the future
This is now no longer the case
At the alter of AI capex, Google is sacrificing the golden goose
Q2 was an amazing quarter, with our AI investments redefining what’s possible across every part of our business.
Alphabet revenue grew 24% YoY and Google Cloud accelerated to 82% growth. We saw exciting momentum across the board from Search to YouTube to the Gemini app (which reached 950M monthly active users). Our model APIs are processing 22B tokens/min (up from 16B+ last quarter) driven by our workhorse Flash models. We’re also seeing great adoption of Gemini Enterprise, used by 90% of the Fortune 100, as well as strong demand for our security solutions.
Outstanding results and momentum, and such an exciting moment—thanks to all of our partners and employees around the world! 🙌 About to hop on the call!

Thank God I’m nothing like the San Francisco software engineer stereotype. I’m into bouldering and rock climbing, I cycle to Marin, and wear Uniqlo not cargo shorts and crocs man. Urban planning is a passion of mine, big YIMBY here. Idk what the nerds are listening to but I’m still bumping old Kanye West and Aphex Twin. I actually touch grass unlike the other swe’s so I’m always on Partiful, scheduling things. I’m smart so outside of work I’m learning Chinese and spend a lot of time on LessWrong. I’m a NeoLib (smart, again) and love Tyler Cowen and Ezra Klein. I only date Chinese women but that’s a coincidence not a fetish. Pickleball, yeah, but ironically. I work on some hardware side projects in my free time. I’m unique, basically.
