they’re not jobs if they’re not valued. they’re not valued if there aren’t customers out there willing to pay them for their great work. needing the government to “create” a job is tantamount to welfare and that level of welfare resolves these individuals to a dependency on the government and lack of economic mobility. and chains our people, collectively, to a more indentured future. you may be well intentioned but you have, and always will, fail to see the destitute folly of government as a job creation engine. i have tried to engage you on this topic, in good faith, with empiricism and reasoning, but you have only dodged my points and pivoted to some populist refrain about the importance of taxation and the evils of productivity-driven success. i can only assume you’re dodging these truths because you and the rest of the politburo leadership have deemed the conversation unsafe speech and put your oligopoly at risk. let’s leave it at that then. perhaps if your ways get their day, we can all bask in the glories of the dark ages ahead.

Together with UC Berkeley we are announcing the laser phase plate - a breakthrough in atomic resolution imaging. This is the brightest continuous wave laser in the world, 100 million times the intensity of the surface of the sun. Phase contrast plays an important role in microscopy, but it was thought close to impossible for electron microscopy, where it would require interfering with an electron beam. Holger Mueller and Robert Glaeser proposed exactly this using a standing wave laser. It has taken over 15 years to make this a reality. Biohub partnered with UC Berkeley and Mueller to support this work and to engineer and build the technology. Contrast has been the critical barrier to achieving atomic resolution imaging of the cell. In cryo-electron tomography, a cellular imaging technology that uses electron microscopy, the low contrast makes it impossible to resolve anything but the largest proteins within their cellular context. The laser phase plate removes that barrier. With advances in AI this breakthrough in contrast will start to open up a new frontier in structural biology, that will allow us to see the molecular machines of the cell, and how they assemble into far more complex and dynamic systems, and understand how they work.

History's first trillionaire is a guy who catches rockets out of the sky with chopsticks and beams internet to every dead zone on the planet. Same guy ships cars that drive themselves, humanoid robots for the factory floor, brain chips that let paralyzed people move a cursor with pure thought, and an AI running on a supercomputer his team stood up in months instead of years. And the people crashing out about his net worth are doing it on the app he owns. The same app governments spent years trying to censor. You cannot legislate a rocket into orbit.

Fun fact: @GavinNewsom has budgeted >300% more tax dollars for a nonexistent California rail system than SpaceX raised in private capital in its entire history as a private company.
Americans are struggling to pay for groceries and gas while Elon Musk becomes a TRILLIONAIRE. When the federal government is for sale, the rich get richer and everyone else gets shafted. The system is rigged.

Amazing to see what un-American socialists Bernie Sanders and Elizabeth Warren have become. They would truly have all Americans poorer and be happy about it. Is actually quite sad, and most Americans wont buy the bullshit.

.@BernieSanders , it is a time to celebrate. @elonmusk has created enormous value for society by building @SpaceX, driving down the cost of rocket launches and creating a global satellite communication network that has brought high speed, low-cost internet and communication access to hundreds of millions and eventually billions of people along with critical advantages for our military and our nation’s defense. SpaceX and its technologies will cause an acceleration in the growth of wages and wealth creation globally, including in some of the poorest communities in the U.S. and around the world. Access to low-cost, high speed communications everywhere will allow children around the world to be educated, families to build businesses, and life-saving medical knowledge and care to be available everywhere. SpaceX will materially bring down the cost of compute, advancing AI and humanity. Meanwhile, 4,000 SpaceX employees yesterday became millionaires, including hourly wage employees who you claim you are trying to help. The Elon Musks of the world drive growth, global GDP, and provide access to goods and services at lower cost that would otherwise not exist. Elon’s nominal trillionaire status is due to his ownership of SpaceX, Tesla, Neuralink, the Boring Company and his other initiatives that have brought new technologies that improve our everyday lives. Elon is not sitting on a trillion dollar pile of cash, jewelry and gold. He is using his controlling stakes in his companies to advance mankind. Elon’s companies don’t pay dividends. They reinvest all of their capital to accelerate innovation and value creation. Elon is working 24/7 for all of us. He deserves respect and appreciation, not smears. Bernie, your socialism would never allow a SpaceX to be built. Socialism has only proven to impoverish mankind and lead to death and destruction. We need to create the conditions for more SpaceXs to be built, not attack the great entrepreneurs who are helping to advance our country.

Tout le monde devient fou parce qu'Elon Musk a une fortune de 1 000 milliards de dollars. Très bien. Faisons les comptes, calmement. L'État fédéral américain dépense 7 000 milliards de dollars par an. La fortune entière d'Elon, accumulée sur 30 ans de travail, représente 52 jours de dépenses de Washington. L'État français dépense 1 700 milliards d'euros par an, 57% du PIB, record absolu du monde développé. La fortune d'Elon, c'est 7 mois de dépenses publiques françaises. Maintenant, la question que personne ne pose : qu'est-ce que chacun a produit avec cet argent ? Washington, avec 7 000 milliards par an : un déficit de 1 800 milliards, une dette de 38 000 milliards, et des intérêts de la dette qui dépassent désormais le budget militaire. La Californie de Newsom a brûlé plus de 15 milliards dans un train à grande vitesse qui n'existe pas. La NASA a dépensé plus de 24 milliards pour développer le SLS, une fusée jetable à 4 milliards le lancement. La France, avec 1 700 milliards par an : un hôpital en crise permanente, une école qui s'effondre dans les classements internationaux, 3 400 milliards de dette, et pas une seule entreprise technologique de rang mondial créée en 25 ans. Elon, avec une fraction microscopique de ces budgets : le Falcon 9 développé pour environ 400 millions de dollars, là où la NASA estimait elle-même qu'il lui en aurait coûté 4 milliards. Dix fois moins cher. Des fusées qui atterrissent. Le coût du kilo en orbite divisé par 20. Starlink qui connecte des millions de personnes que les plans d'aménagement du territoire ont oubliées pendant 40 ans. Tesla qui a forcé toute l'industrie automobile mondiale à basculer vers l'électrique, ce que 30 ans de COP et de subventions n'avaient pas réussi à faire. Donc récapitulons. Les États ont des moyens 10 à 50 fois supérieurs, le monopole de la loi, le monopole de l'impôt, et des décennies d'avance. Elon a beaucoup moins de moyens, zéro pouvoir de contrainte, et il surperforme tout le monde, dans tous les domaines où il entre. Ce n'est pas un hasard. C'est structurel. Quand un entrepreneur alloue son propre argent, chaque erreur lui coûte personnellement, donc il apprend vite. Quand un bureaucrate alloue l'argent des autres, chaque erreur est invisible, diluée, et souvent récompensée par un budget supplémentaire l'année suivante. L'un a une boucle de feedback, l'autre n'en a pas. La conclusion s'impose d'elle-même : le pouvoir de créer des systèmes dans le monde réel doit TOUJOURS être donné aux entrepreneurs qui allouent leur propre argent. Pas parce qu'ils sont meilleurs moralement. Parce qu'ils sont les seuls à payer le prix de leurs erreurs, et donc les seuls capables de corriger. Milei a TOUT compris. Re-regardez son discours de Davos. "L'État n'est pas la solution, l'État est le problème lui-même." Tout le monde a ri en 2024. L'Argentine est sortie de l'hyperinflation pendant que la France cherche encore 40 milliards d'économies qu'elle ne trouvera jamais. L'histoire ne juge pas les intentions. Elle juge l'allocation.

David Friedberg: California’s Voting System Looks Fraudulent, But It’s Working Exactly as Designed @friedberg believes California’s extremely loose election laws enable “appointments” not free elections. Why? The voting data in LA makes no statistical sense. “ Pratt's post-election mail-in ballots declined by 1/3. So statistically, the population of people that send in their ballots late reduced for Pratt by 1/3, increased for Nithya Raman by 80%, and Karen Bass 10% less, if you just look at the mail-in ballots before and after election day as a comparison. I don't know if there's a sociopolitical way that you can assess those statistics and assume that these are individuals casting their individual vote for who they think should be Mayor of LA. Basically, the concentration of incremental votes that Nithya Raman got came around the Skid Row area in Los Angeles. But when you look at the basic statistics of what happened in person, mail-in before, mail-in after Election Day, it becomes a real statistical quagmire on how did this sort of a sociopolitical shift happen in such a way that it did? Now, there was a report published, and they highlighted the 2018 California midterm elections and the challenges that they saw arise in that midterm election because of some of the legislative changes that were made. First, California Assembly Bill 1921 legalized the practice of unlimited ballot harvesting in the state. What that means is that any individual in the state of California has the right to go and collect ballots from any other individuals, regardless of relationship, fill them out, and send them in. California, two years later, 18 months later, also passed a law that made it permanent that every person registered in the state of California would get a ballot, so tens of millions of ballots then get mailed out. Then there was another series of laws that were passed that said anyone can register to vote. You don't need to prove your citizenship. You can use a gym membership card as an example. So anyone can register to vote. There is no proof of ID when you get a ballot. There is no demonstration that the person who fills out the ballot has anything to do with the individual who's supposed to be voting that ballot, and it is legal for an individual to go out and collect hundreds or thousands of ballots, ship them in, and they will all qualify in these kind of mail-in ballot voting processes. So there's nothing illegal or fraudulent going on. In fact, the system is operating exactly as intended. It has been set up and structured in a way that with the right construct, you can get an individual appointed, not elected, but appointed to a particular role in government under a, quote, ‘free election’ in California.”

🚨JEFF BEZOS JUST PUT $100 MILLION INTO A STARTUP WITH NO PRODUCT. Their entire pitch is that the AI industry is doing everything wrong. And that your brain already solved the problem everyone is burning billions trying to fix. The whole AI industry is trapped in one brutal equation: Smarter models need more compute. More compute needs more power. Companies are now building dedicated nuclear plants just to run AI data centers. A single AI server GPU burns over 1,500 watts. Your brain runs on 20. Yet your brain is doing something far more complex than answering a chat prompt. It's learning, reasoning, controlling your body, and processing everything you see and hear on less power than a light bulb. A startup called Flourish just raised $500 million at a $2.5 billion valuation to exploit that gap. Their thesis is simple but radical: The AI industry is optimizing at the wrong layer. Everyone is racing to build more powerful chips. Flourish says the real problem isn't the hardware. It's the architecture. Today's AI models activate enormous portions of their networks for almost every task. Your brain doesn't. It's sparse. Only the neurons needed for a task light up. Everything else stays quiet, consuming almost no energy. Flourish wants to copy that. Their approach comes from a field called connectomics: mapping biological brains neuron by neuron to understand how intelligence actually works. In 2024, scientists fully mapped a fruit fly brain. And here's the punchline: That tiny brain appears dramatically more efficient than modern AI systems performing similar tasks. Flourish wants to extract that efficiency and turn it into software. The man leading the effort has one of the strangest résumés in tech. Thomas Reardon created Internet Explorer at Microsoft. Then he left software, earned a PhD in computational neuroscience, built a brain-computer interface company, and sold it to Meta for up to $1 billion. Now he's trying to reverse-engineer the core algorithm of human intelligence itself. If it works, the implications are staggering. Advanced AI could run locally on laptops and phones instead of massive data centers. The energy requirements of AI could collapse. And the $30,000 GPUs the industry depends on today could become optional. For 70 years, we've built computers that think nothing like brains. Flourish is betting the answer was sitting inside our skulls the whole time.

A Scandinavian economist once boasted to Milton Friedman: “In Scandinavia, we have no poverty.” Friedman replied: “That’s interesting, because in America, among Scandinavians, we have no poverty, either.”
Scandinavians in the US are wealthier than Scandinavians in Scandinavia (data from 2013).
