Letter #327: John Ternus’s commencement speech (2024) • A Letter A Day
Kevin Gee with the transcript of incoming Apple CEO John Ternus’s commencement speech at Penn Engineering in 2024:
»
My first project at Apple was the Cinema Display. It was a large desktop monitor. It had a beautiful clear plastic enclosure that was held together with some screws coming in from the back. These screws were made of stainless steel, and the head of every screw was machined to have a pattern of concentric grooves that shimmered like a CD when light moved across it. I should probably say, if some of you have never seen a CD before, you can ask your parents afterward.
At some point in my first year, I found myself at a supplier facility. I was far away from home, it was well past midnight. I was using a magnifying glass to count the number of grooves on the head of this screw, which, remember, lives on the back of the display. And I was arguing with the supplier because these parts had 35 grooves, they were supposed to have 25.
I distinctly remember stepping back for a minute and thinking to myself, “What the hell am I doing? Is this normal?” And I thought about it, and I realized it might not be normal, but it’s right. It’s right because I’d already spent months working on that product, and if you’re going to spend that much time on something, you should put in your very best effort. Maybe a customer notices, maybe they don’t, but either way, whenever I saw one of those displays on someone’s desk, it mattered to me to know that my teammates and I had considered everything about it and done the very best job we could.
But make no mistake, it’s hard to put that much of yourself into something. It’s stressful, it requires sacrifice, but it’s worth it because our time is finite.
«
There’s more, and it’s a lot shorter than Steve Jobs’s commencement speech with fewer insights, but it gives a first glimpse of the person behind the new chief executive. There’s also a Deadline report which says that he likes the Apple TV streaming service and wants it to be, if anything, more competitive.

CDC blocks study showing Covid shots cut hospital visits after earlier delay • The Washington Post
Lena Sun:
»
A report showing the efficacy of the covid-19 vaccine that was previously delayed by the head of the Centers for Disease Control and Prevention has been blocked from being published in the agency’s flagship scientific journal, according to three people familiar with the decision who spoke on the condition of anonymity for fear of retaliation. The report showed that the vaccine reduced emergency department visits and hospitalizations among healthy adults by about half this past winter.
The move, which has not been previously reported, has raised concerns among current and former officials that information about the vaccine’s benefits is being downplayed because it conflicts with the views of Health Secretary Robert F. Kennedy Jr., who has been an outspoken critic of the shots. Kennedy’s vaccine agenda has received pointed questioning from lawmakers during budget hearings that began last week and conclude Wednesday.
The Washington Post reported two weeks ago that Jay Bhattacharya, who is temporarily overseeing the CDC, delayed publication of the report over concerns about methodology. The report had been scheduled for publication March 19 in the Morbidity and Mortality Weekly Report.
In recent days, a decision was made that the report would not be published, according to two of the people who spoke to The Post.

It’s time. Meet my New Thing • New Things
Joanna Stern:
»
If you’ve read my work at WSJ—or before that at ABC News or The Verge—you know I love consumer tech. I love reviewing it, talking to the people making it and helping people understand it. Mostly, I love having fun with it. That’s what we’re doing here.
So let me answer a few questions.
What are you going to be doing?
At the simplest level: what I’ve always done. Writing and making videos about the devices, apps and services changing how we live. Yes, there will be phones. Yes, Apple stuff. Yes, Google and Android stuff. Yes, tips and tricks. Yes, probably a weird robot. Probably many weird robots.But while writing my new book, I AM NOT A ROBOT—where I used AI in as many parts of my life as possible for a year—I realized Is this a good product? isn’t the main question to ask anymore. The bigger question is: Who is this tech for? Wall Street? Greedy CEOs? AI agents? Actual humans? I want it to be for humans. And I want to cover it that way too: as a human living with it, using it, testing it and trying to make sense of what it’s doing to our lives.
That’s the thread running through everything here—every review, every story, every dumb joke. And if I do this right, New Things won’t be just a publication. It’ll be a group of people asking that question together—and figuring out what kind of future we actually want.Is this journalism written by AI?
Hi! I’m a human. I wrote this. Twenty years of journalism ethics don’t disappear because I started an independent media company and a YouTube channel, and they definitely don’t disappear because there are 700 chatbots on my laptop. Every word you read here—every review, every story, every bad joke—is written by me or by a human on my team. (Say hi, Amaya, David, Adele and Rich. 👋🏻)«
She then points to Google launching vertical tabs for Chrome, which she says is transformative. Personally I have my Reading List (of sites saved for later reading) there, so maybe not such a triumph? But she has to start somewhere.

Global energy markets are on the verge of a disaster • The Economist
»
To gauge how close the world is to energy catastrophe, The Economist has gathered a dashboard of indicators. It suggests that grave damage has already been done. Worse, without a reopening costs could soar, triggering events that cause the fuel system to seize up. A reopening of the strait now would—just—avoid a complete disaster. But some additional pain is already inevitable.
Three factors are pushing the world towards the cliff edge. Oil cargoes available to buy are drying up. Refineries are slashing output of fuel. And demand remains artificially high, especially in Europe. Something big must give somewhere large for energy markets to balance.
Take trade first. One reason the largest supply shock in petroleum history has not triggered global panic is that a near-record amount of oil was already at sea when the war started. As American warships set sail for the Gulf in February, countries there cranked up exports. After the latest deliveries, those seaborne stocks are now exhausted. So are most cargoes of Iranian and Russian oil, which were loitering at sea but found buyers after America eased sanctions on the two countries. Total volumes on water have fallen at record speed. For jet fuel and petrol they are well below historical norms, and possibly close to the minimum required for seaborne trade to function.
This leaves Asia, which used to receive four-fifths of Gulf exports, in a particular bind. Commercial inventories in a few Asian countries are running out. South Korea is due to taper releases from its strategic reserves in the coming days. Japan’s will be exhausted in May. Crude stocks in Asia excluding China fell by 67m barrels, or 11%, in the month to April 19th, according to Kayrros, a firm that estimates inventories using satellite imaging.
«
This topic now seems so important that I subscribed, at this article, to The Economist to be able to follow analysis like this. Nowhere else seems to be drawing all the threads together, and I’m honestly perplexed by the lack of urgency that seems to be shown everywhere else.

Iranian tankers bypass US blockade • Financial Times
Alice Hancock and Nassos Stylianou:
»
At least 34 tankers with links to Iran have bypassed the US blockade since it began, according to the cargo tracking group Vortexa, including several carrying Iranian oil — despite US President Donald Trump declaring the barricade a “tremendous success”.
The US imposed its blockade on all ships entering or leaving Iranian coastal waters from 10am ET on April 13, marking a fresh phase in the Middle East conflict as Washington tries to pressure Tehran into a peace deal.
The embargo was expanded to cover all Iranian vessels on the high seas or those carrying goods that could be used by Iran in the conflict on April 16, according to notices from the US Navy.
US forces have so far detained one container ship in the Gulf of Oman and boarded a sanctioned tanker in the Indo-Pacific. US Central Command said on Tuesday the US Navy had directed 28 vessels to turn back to Iranian ports since the blockade began.
«
If tankers exit the strait, is that good or bad? Iran gets some money so it can.. blockade the strait for longer? Trump’s blockade has created a Chinese fingertrap; a war that neither side can exit.

What will be scarce? • Ghosts of Electricity
Alex Imas:
»
This is most people’s mental model of what AI will do to the economy: if a machine can produce anything a human can, write the brief, generate the image, compose the song, determine the diagnosis from a radiology scan, then the human will be replaced across all facets of production and jobs will simply disappear. Labor will be replaced with capital. David Autor and Neil Thompson push back on this in an important recent paper. They argue that AI won’t simply eliminate jobs; it will reshape the economic value of human expertise. Their framework distinguishes between expert and inexpert tasks within any given occupation. When automation removes the simpler tasks (as accounting software did for bookkeeping clerks), the remaining work becomes more specialized, wages rise, and fewer workers qualify. When it removes the harder tasks (as inventory management systems did for warehouse workers), the job becomes more accessible, employment expands, and wages fall. Same technology, opposite labor market outcomes, depending on which part of the job gets automated.
But Autor and Thompson also consider a starker possibility: that AI advances to the point where human expertise loses its economic value altogether. Under this scenario, AI will eliminate labor scarcity and produce what Herbert Simon once called “intolerable abundance.’’ Automation of production will no longer involve managing a workforce transition, for which we have prior episodes of automation to rely on. We will need tools to maintain social organization, income distribution, and democratic stability without the labor market that has historically held these together.
I want to consider a different scenario, one where automation can replicate human production and the commodities that it produces (a big if!!!), but human labor does not disappear. How could this be the case? A lot of analysis takes the economy as given: there is a set of jobs and a set of goods/services produced by the economy. If the same set of goods/services can be produced by cheaper machines, then these machines replace humans and the jobs disappear. But the economics of structural change, combined with deep-seated features of human preferences, suggests something different: as people get richer, they don’t just want more commodities. They want things that aren’t commodities in the standard sense of the word.
…If this is right, then AI won’t just automate the commodity economy. It will trigger the emergence of something new: a post-commodity economy, where a growing share of expenditure goes toward goods and services whose value is inseparable from the human who provided them.

Ed Miliband unveils move to delink UK gas and electricity prices • Financial Times
Rachel Millard, Ashley Armstrong and Jim Pickard:
»
The UK government will increase taxes on wind and solar farms in a bid to push them on to fixed-price contracts, as part of plans to cut the link between electricity and gas prices in Britain.
The move, confirmed by the government on Tuesday, comes after the Iran war created pressure for a rethink on how electricity prices are set.
The blockade of the Strait of Hormuz has pushed up gas prices and led to higher electricity prices, because gas-fired power stations typically set the wholesale price across the market under Britain’s “pay-as-clear” electricity market design.
Ed Miliband, the energy secretary, said that renewable power stations that currently received subsidies under the legacy “renewables obligation” scheme would be encouraged to sign so-called contracts for difference, under which the state guarantees them a fixed electricity price regardless of the wholesale price, funded by a levy on consumer bills.
They would continue to receive renewable obligation subsidies as well, the government said. Power station owners will be able to apply for the contracts next year. Generators supplying roughly 30% of Britain’s power supplies receive renewable obligation certificates.
Alongside this, ministers will from July increase by 10 percentage points the windfall tax on power generators that are not signed up to contracts for difference, partly to encourage them to do so.
…However, the extent to which the move lowers costs for consumers will depend on the fixed price level the generators receive. Meanwhile, analysts said the threshold for the windfall tax was higher than the typical price of power sold by affected companies.
«
So this is not quite the sundering of pricing to give us cheap renewable power a lot of the time, or even some sort of average. The floor price goes up, but the ceiling comes down?

The first sixty seconds • Jørgen Melau´s Mixed Physiology
Jørgen Melau:
»
When people ask me what kills in cold water, they expect me to say hypothermia. But hypothermia is slow. The real killer is much faster, and it usually strikes before you have even started swimming. Let me try to explain why, and what you can do about it.
1. The cold shock response.
The moment cold water hits bare skin, your body panics. The nerves in your skin fire a huge alarm signal to the brain and the heart. You gasp. You hyperventilate. Your heart rate jumps. Your blood pressure climbs. All of this in a few seconds.Michael Tipton described this sequence in 1989, and it has not really changed since. The first gasp alone is two to three liters of air, pulled in uncontrollably in the first second after you hit the water. If your face happens to be under water at that moment, you do not breathe in air. You breathe in water. This is how strong pool swimmers drown ten meters from a boat.
2. The diving response
At the same time, the opposite reflex is triggered. Cold water on the face, together with holding your breath, sets off what is called the diving response. Your heart slows down. The blood vessels in your arms and legs squeeze shut. This is a very old reflex. Every mammal that dives under water has it, from seals to humans.On its own, the diving response is harmless. On its own, the cold shock response is unpleasant but survivable. The problem is when they happen at the same time.
3. Autonomic conflict
In 2012, Mike Shattock and Mike Tipton gave this problem a name: autonomic conflict. Here is what happens. The cold shock response is telling the heart to speed up, now. The diving response is telling the heart to slow down, now. Both signals are maximum. Both arrive at the same time.«
What Melau doesn’t point out, but becomes clear as you read this, is why people used to tell you not to go in the water within half an hour of eating. The whole of this is fascinating, and important for triathletes and others who have to jump into cold water and try to do things.

It’s not just one thing — it’s another thing • TechCrunch
Amanda Silberling:
»
Sometimes, things are not just one thing — they’re also another thing. This sentence construction (“It’s not just this — it’s that”) has become so common in AI-generated writing that now, it’s no longer just a clue that a piece of writing may be synthetic — it’s almost a guarantee.
That’s why I was not just intrigued when I saw a Barron’s report about how this sentence construction has dramatically increased in corporate communications — I was deeply amused. The report didn’t just remark on the prevalence of this phrasing in corporate communications — it scanned the market intelligence firm AlphaSense’s database to find how often this phrasing was used in corporate news releases, earnings reports, and government filings.
According to Barron’s, this sentence construction isn’t just a quirk of corporate communications — it’s an epidemic, more than quadrupling from about 50 mentions in 2023, to over 200 uses in 2025.
…It’s not just coincidental that generative AI tools use this phrase a lot — it’s a reflection of our writing, which these tools were trained on (without our permission, might I add, which is not just insulting to writers — it’s a violation). And it’s not just this sentence construction — it’s also em-dashes that are now considered a tell for AI-generated text.
This isn’t just a funny trend — it’s symbolic of how reliant these companies have become on AI (though we cannot say for certain if the above missives were AI-assisted). So next time you see a sentence like that, remember that it’s not just a catchy construction — it might be a symptom of something greater.
«
This is perhaps the best way to point to the slow infection of this style into corporatespeak. Though not that slow; the graph shows an exponential increase.

Peter Thiel is building a parallel justice system — powered by AI • Coda Story
Nic Dawes:
»
In 2016, when Peter Thiel killed Gawker, he insisted that he wasn’t attacking journalism writ large.
On the contrary, he told the New York Times, he’d spent $10 million secretly backing Hulk Hogan’s lawsuit against the news outlet because: “I saw Gawker pioneer a unique and incredibly damaging way of getting attention by bullying people even when there was no connection with the public interest… if I didn’t think Gawker was unique, I wouldn’t have done any of this. If the entire media was more or less like this, this would be like trying to boil the ocean.”
10 years later with the aid of an “AI tribunal,” a team of intelligence and law enforcement veterans, and a political climate vastly more hostile to press freedom, he is trying to do exactly that, bypassing the courts, short-circuiting the first amendment, and making it much, much cheaper to indulge in the quasi legal harassment of journalists.
Objection.ai is a new startup funded by Thiel, and cofounded by Aron D’Souza, who worked closely with him on the Gawker case. It promises “a fast affordable way to challenge statements in the media.” Anyone can file an objection, which will trigger an investigation by a team hired, the company says, from the CIA, FBI, and British intelligence agencies. Targeted outlets and reporters will have an opportunity to respond, and the results will be fed to an AI model, which will render a verdict. The complainant, and the target, are asked to agree to binding arbitration, with an unspecified range of potential consequences. Financial details are vague, but the company has said the process will cost around $2,000 — far less than the retainer of a crisis communications expert.
An initial slate of cases includes objections against the New York Times, for reporting on how Thiel’s fellow traveller David Sacks, former PayPal chief operating officer and Donald Trump’s former “AI and Crypto Czar,” uses his White House position to benefit Silicon Valley connections; The Wall Street Journal for its revelations about the doodle contributed by Donald Trump to Jeffrey Epstein’s birthday book (a case recently dismissed by a federal judge); and British reporter Hannah Broughton for an aggregated story in the UK tabloid the Mirror about allegations that Amazon workers were told to continue working while a colleague lay dead on the warehouse floor.
«
I don’t think people are going to agree to this in the US, and it would have only limited applicability elsewhere.
