Having spent a long time watching Elon Musk, and having talked with him, I believe I understand what he understood before almost anyone else. And it's something every one of us needs to understand now. Western civilization is not one civilization among many. It is the one that gave the world freedom of thought, modern science and the dignity of the individual. And it is under attack. Not by peoples, but by ideologies that want it dead. If it dies, the world will not become more just. It will become poorer, more brutal and darker. For everyone, including those who hate it. Why? Because civilizations are not interchangeable. We were told that any culture could be blended with any other, like mixing colors, and that the result would always be harmonious. It isn't true. A society where women are equal to men cannot coexist without friction with a worldview in which a woman's testimony is worth half a man's. A society where you can criticize God, change your religion or have none cannot absorb, without fracturing, a worldview in which apostasy is paid for with your life. Every people has its own genius and moves at its own pace. But not all values are equal, and you cannot build a nation on laws that contradict each other. Saying so is not racist. Racism is about blood. I am talking about laws, customs and values. And those values belong to no race: a Japanese, a Senegalese or an Iranian can make them his own, and millions have. That is exactly why they are worth defending. Let's remember where they come from. It all begins in Greece. In Athens, for the first time, men decide that truth does not descend from a throne but is sought through reason, and that a city governs itself through debate. Socrates chooses death rather than give up thinking freely. At Salamis, a handful of free cities stops the greatest empire in the world. Then comes Rome. Rome invents law that binds everyone, the citizen who holds rights, the Republic. And one immense idea: you can become Roman without being born Roman. You become Roman by adopting its laws. Christianity adds the most revolutionary idea in history: every human being, slave and emperor alike, has infinite worth. Then France. The cathedrals, those ships of stone our ancestors built over centuries for descendants they would never see. Descartes, Pascal, Voltaire. The Declaration of the Rights of Man. And Napoleon, who gives France the Civil Code, the lycées, and one simple principle: careers open to talent. Murat, the son of an innkeeper, ends up a Marshal of the Empire and King of Naples. The Civil Code spreads across much of Europe and still shapes the law of dozens of countries today. And this civilization goes on to abolish slavery, which had been practiced on every continent since the dawn of time, to push back the plague, smallpox and the night itself, and to set foot on the Moon. Peoples of the West, be proud of this history. Proud does not mean blind. Every civilization has committed crimes: conquest, slavery, war. Ours is the one that went furthest in examining its own faults, to the point of abolishing what it had once practiced. This capacity to question itself is its greatest strength. And that is exactly the strength now being turned against it. Because for decades, this magnificent system has been getting hacked. Not by an army. By an alliance of two forces that have nothing in common except one enemy: us. The first is communism. It lost the economic war, lost the Cold War, lost history's verdict with its tens of millions of dead. But it never lost the universities. It survived by changing costumes: class struggle became the struggle of the oppressed against their oppressors, and the West was declared guilty of everything. It taught our children to be ashamed of their ancestors, their borders and their culture. It is the root cause, because before you can bring down a civilization, you have to take away its will to defend itself. The second is political Islam. I am not talking about Muslims, many of whom came here precisely to escape this ideology and are its first victims. I am talking about a political project that wants to place religious law above civil law. It has no doubts. It feels no shame. It rushes into the void the first one dug. One disarms. The other advances. And let no one on the left believe they will stay in control. History has already staged this play. In 1978, Michel Foucault was enthusing over the Iranian revolution. Iran's communist party, the Tudeh, backed Khomeini and called on Iranians to vote for his Islamic constitution. By 1983, its leaders had been arrested, the party banned, and its chiefs paraded on television to confess their “crimes.” In 1988, thousands of political prisoners were executed, communist activists among them. The second always ends up devouring the first. Useful idiots are only useful for a while. So here is my call to every Western people. To the French, the Italians, the Poles, the Germans, the Spanish, the Americans, to all of you. We are at a turning point. What we do in the next ten years will decide what our grandchildren are allowed to say, believe, write and love. I am not asking you to die for the West. I am asking you for something harder: to live for it. Learn its history and pass it on. Have children. Speak without fear, even when they call you every name in the book. Vote, get involved, run for office. Build companies, schools, factories, families. Refuse the shame they are trying to inject into you. And stop surrendering anything that makes us who we are: freedom of thought, equality before the law, the dignity of every person. The historian Arnold Toynbee understood it: civilizations are not murdered, they commit suicide. And those who think they can let the West fall without paying the price should remember the Iranian communists. They helped tear down what they despised, and then they were next. The Greeks at Salamis were outnumbered. They won because they knew what they were defending. We are the heirs of Athens, Rome, Notre-Dame and the Civil Code. It is no accident that the rockets that will carry humanity to Mars are being built in a free civilization. It is time to prove ourselves worthy of what we were given. The West is worth defending. And no one will defend it for us.

TESLA UPDATE: I've been driving a borrowed Tesla for two weeks now, to try it out. And I have to amend my first impressions in which I was super annoyed by things like lack of precise speed control during self-driving. After two weeks, I actually find the Tesla vehicle to be really impressive, and some of the quirks that annoyed me at first were just things where I needed to learn a different way of doing things. It is a totally different driving experience. Nothing like typical automobiles. Like not having an ON/OFF button really freaked me out a first, and then after a period of time, you realize you don't need it. I've really come to love the "pet mode," and the self-driving features are so incredibly good, that I've never felt the car did anything unsafe. In fact, at one point driving at night, it actually dodged a pretty large chunk of roadkill that might have damaged a vehicle if struck. I don't own any stock in Tesla (or anyone else for that matter, since I don't own stonks, period), but after a couple of weeks of driving one, I have to say this really is the future of personal transportation. I've gone back and driven my own vehicle a couple of times, and when I do, I really miss the self-driving. The onboard Grok voice assistant is simply outstanding. It can find addresses for you even if you don't know the full name of the place you're going. It can bring up settings on the screen for you. All you have to do is ask it verbally. Is the car spying on me during all this? Well, I'm not driving it under my own name, that's for sure! Am I worried that it's watching my face as I drive to make sure I'm not snoozing at the wheel? Not in day-to-day use, no, but I'm still going to keep an older vehicle around for truly anonymous off-grid driving for when those scenarios are necessary. Just in case. Will I buy a Tesla? Yeah, as soon as they have a Tesla SUV. I need something bigger than what they currently offer, and not a pickup truck, either. I need a Tesla SUV or a Tesla van. Big dog, lots of computer hardware being hauled around, power stations, etc. So if anyone from Tesla is listening, please make a SUV that's actually large enough for Texans who have a lot of gear. :-)

Over the last week I built a bottoms up SpaceX financial model through the end of 2028 The numbers that came out are insane There are wide error bars given how quickly things are changing but I wanted to distill something complicated into something that can at least be debated * This is not investment advice!!! ** Sequoia is a major SpaceX shareholder *** Past performance is not indicative of future results

Grok is taking over my phone usage. $SPCX apps were 50% of my screen time last week. Lots of X (but a lot of that is Grok) plus Grok and Grok Bot. The point is that SpaceX could make a phone optimized for Grok at the OS layer that would beat the iPhone for 50%+ of my phone usage. $AAPL

I’ve spent a few days thinking about the Tesla Roadster reveal and landed somewhere I haven’t seen much discussion. I’m neither a Tesla fanboy nor a Tesla hater. And I couldn’t care less whether what we saw technically qualifies as a flying car. Three takeaways: (1) The risk of that live demonstration going horribly wrong was real. Almost no CEO would willingly expose their company to that kind of public humiliation for a product with so little financial upside. Elon did. (2) That willingness to attempt the seemingly impossible is what makes Tesla special. It’s also arguably Elon’s greatest contribution to America. He’s helped bring back something we’ve lost. The American spirit of chasing big scary ideas that most people think are impossible. That mindset is spreading across a new generation of founders and its long term impact on America’s future could dwarf anything Tesla ever sells. I think this is deeply underappreciated. (3) Can we just acknowledge how insanely cool that moment was? We’ve reached a strange place culturally where even extraordinary feats of human ingenuity immediately become arguments about why they don’t count. Not everything needs to be a debate. Sometimes we should just be able to stand back together and marvel at what humans are capable of. I’ve been both bullish and critical of Tesla’s ambitions over the years. But watching Elon and his team push the boundaries of what’s possible reminds me why I’m glad we have him. Whether the Roadster ever makes Tesla a dollar or impacts $TSLA stock price is almost beside the point. We need more people willing to risk failure in pursuit of things the rest of us think are impossible. Because when they succeed we all win.

Something important is happening with FSD v15, and I haven’t seen it framed this way. For years, Tesla used the customer fleet as the debug layer. New builds went to owners first. Interventions, disengagements, and video from millions of supervised miles told Tesla what still broke. Robotaxi was not the proving ground. Owners were. v15 reverses that. Early v15 is already running unsupervised on Tesla’s own Robotaxi fleet. Customer cars are still on supervised v14. The newest stack is being validated internally and on a geofenced commercial fleet before it ever becomes a public FSD update. That is a strategy change. It does not mean v15 is a small, safety-neutral patch. Tesla has described it as a step-change: multiple parallel improvement tracks, a much larger model, and the software they want before they scale unsupervised operation. The point is different. Tesla now thinks it can ship that stack into cars with no safety driver without first farming bugs out to private owners. That matters for unsupervised FSD on privately owned cars. The day Tesla removes the requirement to supervise, it also loses the intervention dataset that built FSD. You cannot keep improving a system the same way if the customer is no longer supposed to grab the wheel. Unsupervised FSD only works long-term if Tesla can keep iterating with internal testing, simulation, and its own fleet. Putting v15 on Robotaxi first is an early sign they believe that loop is starting to work. I still expect the first unsupervised customer use to be limited to the Robotaxi geofences. Nationwide unsupervised FSD on private cars is a later step, not the next one. But the sequence has changed. The customer fleet is no longer the lab. Robotaxi is. Robotaxi getting v15 before owners is an early sign unsupervised FSD is being prepared for the public, not just the Robotaxi fleet.

I was on the tail end of a 500 mile drive back from Omaha yesterday with my 77 year old dad and we nearly had a very serious accident, possibly deadly for the other driver. Look at this older Toyota Corolla blow this light at 60mph more than 3 seconds after it turns red. If it was me driving, because I could not see the Corolla as it was occluded by the stopped cars, we would have had a head on collision or I'm mid-turn and he would have impacted my dad's side of my @cybertruck. Thankfully @tesla FSD was doing the driving and it has superhuman reaction to brake pedal application time (aka PRT = perception response time) of about 0.25s while very good human is 0.8-0.9s or average human is 1.5-2.5s. This is life saving technology and it may have saved one yesterday. Thanks to @aelluswamy, @elonmusk, and the whole team behind this.

Tesla just sent me a marketing email with this video in the link. It's about a 93-year-old woman who got her independence back thanks to FSD. Bravo! Aging boomers with disposable income are an ideal target market for FSD. It's about time they knew it existed. youtu.be/g1GSVkENNYo?is=0jGU…

I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon. And I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style. Tesla open sourced its patents and we made the Supercharger network available to all competitors, even though we could have made it a walled garden. SpaceX launches competing satellite systems with no increase in price or use of unfair terms. Even my worst enemies can attack me on this platform. …
