Steve Jobs

Tue, 28 Mar 2023 00:00:00 +0000

Steve Jobs built Apple on a single, unbending conviction: control everything. Not just the software or the look of a device, but the chips inside it, the operating system, the store where you bought it, even the exact shade of beige on the case. That end-to-end control is what let Apple ship products that felt whole in a way rivals never matched — the iPod wasn’t just a music player but hardware, software, and the iTunes Store working as one. The same refusal to accept anything less than his vision made Jobs brutal to the people building it. He called employees “assholes” and their work “shit,” and could burn days arguing over the roundness of a corner. The genius and the cruelty came from the same place.

Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future

Tue, 16 May 2023 00:00:00 +0000

Elon Musk builds companies by taking an implausible mission — getting humanity to Mars, getting transport off fossil fuels — and treating it as a literal deadline that reality has no right to negotiate. Ashlee Vance’s biography argues that this single move explains everything else: the rockets that land themselves and the trail of ruined marriages, discarded assistants, and burned-out engineers behind them. Musk absorbs failure and expense that would stop anyone else because, to him, the schedule is not optional.

Zero to One: Notes on Startups, or How to Build the Future

Sun, 05 Mar 2023 00:00:00 +0000

The most valuable companies aren’t built by copying what already works. Peter Thiel draws a hard line between two kinds of progress: horizontal progress, going from one to n by spreading existing ideas, and vertical progress, going from zero to one by making something that never existed before. Manufacturing more smartphones is horizontal. Inventing the smartphone is vertical. The first is easy to picture and easy to copy; the second is hard precisely because you have to see what almost no one else can. Real value, Thiel argues, comes from that second kind — and the reward for it is monopoly.

Bad Blood: Secrets and Lies in a Silicon Valley Startup

Wed, 30 Aug 2023 00:00:00 +0000

Silicon Valley loves a founder who fakes it until they make it, and that tolerance is mostly harmless — right up until the product is a medical diagnosis. Theranos is the story of what happens when it isn’t. Elizabeth Holmes, who feared needles and had wanted to be a billionaire since she was ten, sold an irresistible pitch: a credit card–sized device that would draw blood from a single pinprick, feed it to a toaster-sized machine called Edison, and test for over 200 diseases cheaply, in every home. By 2014 the company had reached a $9 billion valuation and signed deals with Walgreens and Safeway. The device never worked.

21 Lessons for the 21st Century

Mon, 20 May 2024 00:00:00 +0000

The people who own the data and biotech of this century may end up owning everything, including us. That threat runs under all twenty-one of Harari’s essays. Whoever masters the ability to predict and shape human behavior at scale could fracture our species into a genetically and cognitively enhanced elite and a vast underclass with no economic use at all. The old stories that once organized political life—fascism, communism, liberal democracy—all spread through simple emotional narratives rather than data, and any story that wants to matter now has to make sense of artificial intelligence, big data, and bioengineering. That is hard, because humans have always been better at building tools than foreseeing what they do. It is easy to dam a river; it is nearly impossible to predict what the dam does to the whole ecosystem. The same goes for redirecting the flow of our own minds.

Digital Minimalism: Choosing a Focused Life in a Noisy World

Tue, 09 Jul 2024 00:00:00 +0000

No one ever sat down and decided to spend their life this way. You picked up each app for a small, reasonable convenience—keeping up with friends, glancing at the news, filling a dead minute in line—and only later noticed that these tools had taken over your time and reshaped your behavior. Newport’s first move is to get you off the hook and onto the real culprit. This isn’t a failure of willpower. Tech companies deliberately built their products around the psychological levers that make behavior addictive: intermittent positive reinforcement and the craving for social approval. He quotes a blunt verdict on the industry—that its leaders should stop pretending to be “friendly nerd gods building a better world” and admit they’re “just tobacco farmers in T-shirts selling an addictive product to children,” because checking your likes is the new smoking.

Stolen Focus

Tue, 20 May 2025 00:00:00 +0000

You can’t concentrate, and it isn’t your fault. That’s the claim at the center of Johann Hari’s investigation into why sustained attention has collapsed across whole populations. The usual response — blame yourself for weak willpower, download a blocker app, try harder — aims at the wrong target. Attention didn’t erode because millions of people simultaneously lost their discipline. It eroded because the environment we live in was rebuilt in ways that make deep focus nearly impossible, and reclaiming it is less a personal project than a fight over how that environment gets designed.

The Anxious Generation

Fri, 22 Nov 2024 00:00:00 +0000

Between 2010 and 2015, adolescent mental health fell off a cliff. In the United States, teen depression climbed by roughly 150 percent. By 2020, one in four teenage girls had lived through a major depressive episode in the previous year. Anxiety, self-harm, and suicide rose in the same window, and not just in America — the pattern showed up across the developed world. Jonathan Haidt argues that only one explanation fits the timing, the scale, and the global reach: childhood migrated onto smartphones, and young brains weren’t built for it.

Permanent Record

Sat, 15 Mar 2025 00:00:00 +0000

The same internet that made life convenient made it cheap to watch everyone at once. That is the discovery at the center of Edward Snowden’s memoir, and he made it from the inside, as a contractor with the keys to the United States’ surveillance machinery. Centralized servers, undersea fiber-optic cables, and quiet partnerships between the government and the biggest tech companies turned blanket, retroactive surveillance from a technical fantasy into something trivial to run by default. Snowden’s argument is that when a capability becomes that cheap, it gets used—and that a society which accepts it has quietly decided its citizens have no rights worth protecting.

Algorithms to Live By: The Computer Science of Human Decisions

Mon, 11 Sep 2023 00:00:00 +0000

Most of life’s hardest decisions aren’t hard because you’re bad at thinking. They’re hard because you’re solving problems that have no perfect answer: too many options, too little information, too little time. Computer scientists have spent decades on exactly these problems, and the strategies they worked out for machines turn out to be good advice for people. An algorithm is just a finite sequence of steps for solving a problem. Following a recipe is one, and so is making a pros-and-cons list, only less precise. The trick is knowing which algorithm fits which decision.

Life 3.0

Sat, 03 Jan 2026 00:00:00 +0000

Intelligence is goal-achieving computation. Strip away the mystique and that’s all it is — the ability to accomplish complex goals — and nothing in that definition requires flesh, neurons, or a billion years of evolution. Max Tegmark’s whole argument rests on this: “matter doesn’t matter.” Memory, computation, and learning are physical processes that non-biological matter can run just as well as brains do. Which means a machine could one day out-think us, and the trouble it causes won’t come from hatred. It will come from competence aimed at the wrong target.

Abundance

Wed, 25 Jun 2025 00:00:00 +0000

America keeps choosing scarcity. We say we want to stop climate change, then shut down zero-carbon nuclear plants and protest solar farms. We call housing a human right, then make it excruciating to build a home in our richest cities. We say we want cures, then fund a research system that pulls scientists away from their most promising work. Ezra Klein and Derek Thompson build their whole argument on a thesis so plain it almost sounds naive: to have the future we want, we need to build and invent more of what we need. The problem isn’t that America lacks money or talent. It’s that we’ve spent fifty years writing rules to stop things from getting built—and those rules no longer tell the difference between the projects worth blocking and the ones we desperately need.

Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism

Thu, 20 Mar 2025 00:00:00 +0000

Sarah Wynn-Williams talked her way into Facebook because she believed it could do what governments couldn’t. She’d watched the platform coordinate rescue and relief after the Christchurch earthquake when official channels failed, and after years as a UN diplomat frustrated by bureaucracy, she was convinced this was where one person could actually change things. She pitched the company on a global policy role and got it. What she found was the opposite of what she’d imagined: a leadership so cushioned by wealth and scale that its decisions had come unmoored from their consequences, inside a company that treated anyone who named the harm as the problem.

The Bitcoin Standard: The Decentralized Alternative to Central Banking

Mon, 02 Dec 2024 00:00:00 +0000

Money only works when nobody can make more of it easily. That single idea runs through Saifedean Ammous’s history of currency, and it’s the lens he uses to judge everything from Rai stones to the dollar. When money is hard to produce, it holds its value, people save, and prices tell the truth. When a government can print it at will, whole societies drift toward debt, short horizons, and broken price signals. Bitcoin matters, he argues, because it rebuilds the one property that made gold work — scarcity — in a form no state can dilute.
