Designer, investor, nomad. Temporarily embarrassed billionaire.

If you want to do something great with your life—whatever that means to you—remember this: you get an unlimited number of tries. The only constraining factor is your lifespan. The worst things you can do are: care what other people think, not take risks, fail slowly, give up.

We are about to learn so much about the universe. This is the most exciting time to be alive since humans discovered fire.
🚨wtf. OpenAI says its new internal model it began training just 24 days ago has already resolved more than 100 long-standing open problems across most areas of mathematics. The pace has surprised even OpenAI's own mathematicians. An independent group including Edward Witten, Timothy Gowers and Martin Hairer is now helping assess the results and coordinate how they are released.

Q: Are you concerned about reports of weapon shortages, the strain on the forces, is the U.S. Military big enough to handle threats around the world including China? Vance: Look, we're clearly big enough to handle threats around the world including China…

Siegel on COVID Vaccine: I have to add that recent studies since then make it look like it’s totally safe during pregnancy Faulkner: Has the vaccine changed in a way that’s made it more safe for pregnant women? Siegel: I think the studies that were done were better. I think it’s safe during pregnancy. Covid itself is dangerous during pregnancy.

For most of its life, Siri could barely set timers reliably. Now, in iOS 27, I can’t trip it up.

Forcing users to choose how legible they want UI controls to be is wild. Apple's designers should obsess over where this setting belongs and make it the default. macOS/iOS have always been opinionated about these kinds of things. An abstract UI legibility slider is not the way.

The new Siri in iOS 27 is incredible—it works almost flawlessly with even ridiculously complex asks. Well worth the two years of waiting while Apple figured it out. Almost no notes. Both the design and functionality are as good as I could have hoped for.

This is perhaps the most hilariously ugly car they could possibly have designed. Everything about it screams Fisher Price car for adults. It even amplifies the sound of the electric motor into the cabin. It’s like a parody.
Ferrari has just officially unveiled its first ever all-electric car, called the Ferrari Luce. • Starting price: $640,000 • Interior co-designed with Apple's former head of design, Jony Ive • Range: 280 miles (expected EPA) • Peak charging speed: 350kW • 122 kWh battery • 1,050 horsepower • 0-60mph: 2.4s • 800v • Four-door four-seater • Four electric motors • OLED screens • Weight: 4,982 lbs • Front motors spin to 30,000 rpm, rears hit 25,500 rpm • Car uses an accelerometer to capture real vibrations from the electric motors & rear chassis. An algorithm filters out unpleasant frequencies and amplifies only the more “musical” sounds. This can be heard inside and outside the car. • Paddle shifter on steering wheel changes how aggressively torque is delivered, with five different levels • The trunk has 21.1 cubic feet of space, the largest luggage capacity the company has ever offered • 197.6 inches long, about as long as a Tesla Model S U.S. deliveries start in Q2 2027.

Tim Cook is leaving Apple with an insane record as CEO. One of the greatest who ever did it. “Under Cook’s leadership Apple has grown from a market capitalization of approximately $350 billion to $4 trillion, representing a more than 1,000% increase, and yearly revenue has nearly quadrupled, from $108 billion in fiscal year 2011 to more than $416 billion in fiscal year 2025.”

Listening to NASA’s science teams enthusiastically talk to the Artemis II astronauts is incredibly inspiring. The passion and excitement is visceral and real. You can hear the smiles as they make new discoveries. It’s a beautiful contrast against brain-rot political discussion and AI doomerism that has saturated the news lately.

Tonight’s Artemis II launch to the moon is going to cost every American about $12 each. An Artemis launch costs $4.1 billion, is 95% single-use, and is largely based on technology from the 1980’s. It’s insanely overpriced, but I’m willing to pay $12 to watch a rocket take humans back toward the moon. Can’t wait.

If you’re not a software engineer, this should be a wakeup call to what has happened in the past few months with AI engineering tools. Everything has changed. Now we get to watch as companies learn how to either use these tools in earnest or slowly fall behind.
we're making @blocks smaller today. here's my note to the company. #### today we're making one of the hardest decisions in the history of our company: we're reducing our organization by nearly half, from over 10,000 people to just under 6,000. that means over 4,000 of you are being asked to leave or entering into consultation. i'll be straight about what's happening, why, and what it means for everyone. first off, if you're one of the people affected, you'll receive your salary for 20 weeks + 1 week per year of tenure, equity vested through the end of may, 6 months of health care, your corporate devices, and $5,000 to put toward whatever you need to help you in this transition (if you’re outside the U.S. you’ll receive similar support but exact details are going to vary based on local requirements). i want you to know that before anything else. everyone will be notified today, whether you're being asked to leave, entering consultation, or asked to stay. we're not making this decision because we're in trouble. our business is strong. gross profit continues to grow, we continue to serve more and more customers, and profitability is improving. but something has changed. we're already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company. and that's accelerating rapidly. i had two options: cut gradually over months or years as this shift plays out, or be honest about where we are and act on it now. i chose the latter. repeated rounds of cuts are destructive to morale, to focus, and to the trust that customers and shareholders place in our ability to lead. i'd rather take a hard, clear action now and build from a position we believe in than manage a slow reduction of people toward the same outcome. a smaller company also gives us the space to grow our business the right way, on our own terms, instead of constantly reacting to market pressures. a decision at this scale carries risk. but so does standing still. we've done a full review to determine the roles and people we require to reliably grow the business from here, and we've pressure-tested those decisions from multiple angles. i accept that we may have gotten some of them wrong, and we've built in flexibility to account for that, and do the right thing for our customers. we're not going to just disappear people from slack and email and pretend they were never here. communication channels will stay open through thursday evening (pacific) so everyone can say goodbye properly, and share whatever you wish. i'll also be hosting a live video session to thank everyone at 3:35pm pacific. i know doing it this way might feel awkward. i'd rather it feel awkward and human than efficient and cold. to those of you leaving…i’m grateful for you, and i’m sorry to put you through this. you built what this company is today. that's a fact that i'll honor forever. this decision is not a reflection of what you contributed. you will be a great contributor to any organization going forward. to those staying…i made this decision, and i'll own it. what i'm asking of you is to build with me. we're going to build this company with intelligence at the core of everything we do. how we work, how we create, how we serve our customers. our customers will feel this shift too, and we're going to help them navigate it: towards a future where they can build their own features directly, composed of our capabilities and served through our interfaces. that's what i'm focused on now. expect a note from me tomorrow. jack

Imagine designing iOS, an operating system used by billions of people—literally changing the world—and then following it up with… a car interior design for a few thousand rich people. Absolutely shameful waste of talent. Insanely beautiful, made for no one.
After many years of development, I’m excited to share the interior of the first electric Ferrari designed by LoveFrom. Tactile controls and digital interactions blend into one cohesive interface, shaped through deep collaboration across engineering, interaction, graphics, typography, sound, and industrial design. So incredibly proud of the thoughtfulness and care the team brought to every detail. ferrari.com/en-US/auto/ferra…

These new icons sacrifice the logical representations of each app’s function to the rookie mistake of desiring absolute visual consistency over generally good design. A couple of them are so abstract they don’t make sense. I hope whatever design team Apple has left after the reign of Alan Dye can pull together their talent and power to once again do truly great, world-changing work.

I was at the doctor’s office the other day, and there were three middle-aged women behind the desk sending faxes, stapling things, making calls, changing appointments, and filling insurance forms. Made me wonder whether their jobs or the doctor’s will be safer in a decade.

Liquid Glass is a design cancer. It consumes and overwhelms everything it touches by adding intense distortions, drop shadows, lighting effects, and unnatural spacing to controls and UI in ways that make them harder to see and understand. It is pretty, and seductive, but it makes every interface it touches worse by prioritizing fun effects over common sense design principles like contrast, uniformity, readability, and sane information density. Liquid Glass is the antithesis of great UI design: it is fashion. Form over function. Great design “isn’t just what it looks like, it’s how it works”. And Liquid Glass makes nearly everything it touches look pretty, but work worse.

Anthropic’s web crawler is terrible—it has been pounding my servers for the past couple of weeks, crawling at insane speed and sometimes requesting the same pages 5-50 times per second for hours. These new AI crawlers all have awful web etiquette—and there's no way to stop them.
