Friends, there is a common view of God as the supreme being among many beings—as the biggest and greatest of all beings. But this is a false understanding of God, who is, as Aquinas says, “ipsum esse subsistens”—the sheer act of “to be” itself. In other words, he is the creative ground from which all finite reality comes. God is not a being in the world like the ancient mythological gods and goddesses but the creative source of all that is.

Dusting off this tweet from April because this gap in shared understanding of LLM capability is *widening*. It's now less "two groups of people speaking past each other" and more a sharp funnel. - Napkin math somewhere around 6B people (~75% of the population) have barely come in contact with LLMs at all. - Around 1-2B (~20%) are casual and infrequent users of free-tier ChatGPT-like products. This group sees derpy chatbots and treats them a bit like a better Google search, a writing aid, or etc. Maybe an agent tries to book you a flight. I have non-tech friends who (reasonably, imo) say they have not much use for it at all. Even many professionals outside of math&code are in this tier. For example, execs and many other functions spend a lot of their time talking to other people, so while they understand what is happening intellectually, it is still second-hand and a bit abstract. - Now we get to professional use of frontier-grade LLMs in math&code. Somewhere around 20M people (0.2%) see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt. Building apps, copying apps, translating apps, decompiling apps from binaries... This has all happened very quickly and recently - less than 1 year ago, I was writing code manually by hand, typing memorized computer code commands into a code editor character by character, occasionally pressing Tab to autocomplete a little chunk of code. - And finally we get to the ~5,000 people (~0.00006%) with access to frontier-grade systems internally. The external world has seen the preview. It looks like swarms of thousands of agents collaborating over weeks on software mega projects: minting zero days, running cyber attacks and defenses at machine speeds, discovering new science, advancing the frontier of mathematics. Things that would have taken top professionals in the industry years of work. Meanwhile, human review and comprehension are starting to fall behind. For example, people are still involved in the "archeology" of the OpenAI-HF incident from many months ago. Mathematicians may be poring over the 722 manuscripts on frontier mathematics for a while. The funnel is driven by a combination of factors: 1. The impact scales with ambition, problem size, and horizon. A question with a paragraph answer barely stresses the system. You need a reservoir of big, difficult problems that you really care about. This aspect drives the consumer / professional dimension of the funnel. 2. The jaggedness of the system (which I have written about a lot separately). Capability peaks in domains that are digital, verifiable and economically valuable. This is because LLM capability emerges from reinforcement learning on verifiable rewards on a curated environment mixture driven by revenue potential. This aspect primarily drives the area (e.g. math&code) dimension of the funnel. 3. Access. Free-tier, paid-tier, internal. So this is the weirdness of the moment. The general public has mostly not interacted with these systems. When they have, it looks like a derpy chatbot. The majority of professionals still see only a modest uplift. And a small sliver of professionals are experiencing the vertigo of the curve going vertical. And it is all happening at the same time.

Judging by my tl there is a growing gap in understanding of AI capability. The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code. But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along. So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions. TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

In an age dominated by technology, in which efficiency and profit often take precedence, it is so important that we continue to cultivate a spirit of contemplation and allow time and space for beauty. Such an attitude will greatly help humanity, especially young people, to discover the ability of art to uplift and reveal the depths of the human spirit and our openness to the divine. Contemplation presents a marvelous opportunity to encounter the God who is Beauty.

“Duc in altum.” Put out into the deep. St. John Paul II repeatedly returned to Christ’s words to Peter in Luke 5:4 as a call to courage—a call to leave the safety of the shore and trust Christ in deeper waters. He challenged a generation: “Do not be satisfied with mediocrity.” “Do not be afraid to be holy!” And he reminded us that when Christ calls us into the deep, we do not go alone. Faith was never meant to be comfortable. Do not be afraid. Go deeper. Put out your nets. "Duc in altum." — Jim Caviezel

Yes, this result cost millions of dollars. But remember that when @OpenAI announced o3 it cost ~$500,000 to score 87.5% on ARC-AGI 1. Today, Astra scores higher for ~$20. In 2025 it took us and GDM an enormous amount of compute to achieve IMO gold. For the 2026 IMO, anyone with a $20/month ChatGPT subscription could do it. Massively scaling test-time compute gives us a glimpse of the future. I believe that a year from now everyone will have an AI at their fingertips capable of solving problems of this caliber.

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

Friends, for the wokeist philosophy that dominates today, empathy—feeling the feelings of the other and not harming those feelings—is treated as a supreme value. But while empathy is perfectly good and decent, the Bible teaches that love, not empathy, is the supreme value. And love does not mean, primarily, feeling the feelings of the other or not hurting those feelings; it means willing the good of the other—and that can be, as Dostoevsky said, “a harsh and dreadful thing.”

Engineering our immune cells has successfully treated many types of cancer and even led to cure of some autoimmune diseases. But the engineering of cells was done outside the body, is highly complex, takes 3 to 6 weeks, and is not scalable. But now there are many in vivo (inside the body) Phase 1 clinical trials reading out soon. Watch this space. nature.com/articles/d41573-0…

One day after daraxonrasib’s FDA approval, a new study suggests another way to block RAS signaling, a major cancer driver. The compounds change RAF’s shape so RAS cannot bind, with activity across KRAS, NRAS and HRAS models and, when combined with a BRAF inhibitor, in melanoma resistant to BRAF inhibition. Still preclinical and not yet selective enough for clinical use, but an interesting angle as resistance to RAS inhibitors becomes the next question. @NatureComms *

At midnight on February 6th, earlier this year, the doorbell to our apartment rang. The doorbell was followed by a pounding on the door. I answered the door and a security person in our building handed me his phone. It was my oldest daughter Eloise. She had found my 26-year-old daughter unconscious on the floor of her apartment and had called 911. The EMT team was already there, but they did not know what was wrong with Lucy or to which hospital they would take her. I threw on some clothes and jumped in an Uber heading east toward Brooklyn. (Lucy lived alone in Williamsburg.) On the way, I learned that they were taking her to Elmhurst, a City trauma hospital in Queens. I arrived about five minutes after the ambulance to join Eloise, Lucy’s mom, and a friend, and waited to learn what was wrong. After about 15 minutes, I asked a nurse where she was. I looked over his shoulder to his computer. Next to her name, it said “non-responsive.” I walked into the emergency room and wandered around looking for her until I found her unconscious on a gurney surrounded by several doctors and nurses. By about 2:30am with the results from a CAT scan, Lucy’s doctors had determined that she had a massive brain hemorrhage and would need an emergency hemicraniectomy to release the pressure on her brain and remove the blood from the hemorrhage. I called our wonderful friend and family doctor Eddie Fisher and explained what was going on. He woke up Josh Bederson, Chairman of Neurosurgery at Mount Sinai, to find out more about Zach Hickman, the neurosurgeon on call that night. Dr. Bederson said Hickman was an excellent surgeon, which was comforting as we had no choice. The surgery to save Lucy’s life began around 3:15am and finished around 5:30am. It was successful. The following day, I joined Lucy in an ambulance while she was being transferred to Mount Sinai on Madison Avenue. Later that day, we determined from Lucy’s Oura ring that her hemorrhage had occurred around 9am, which meant that more than 19 hours had passed from the time of the hemorrhage to the completion of the surgery to release the pressure on her brain (I only wish @ouraring had an alert for this kind of a medical event. Imagine it could call a family member if the wearer doesn’t cancel the alert). I later learned that the standard of care is not to do surgery to save a patient with a large brain bleed if more than five hours have passed since the hemorrhage. Even when the surgery is done, I was told that the likely outcome for the patient is a few months in a nursing home and death from pneumonia. When I met Lucy’s doctors, I did my best to inspire them: “Let’s see what can be accomplished if we give her the best care possible and we invest unlimited resources to restore her to life.” And I promised that whatever we learned we would make available to everyone. Dr. Chris Kellner, her neurosurgeon, and Dr. David Putrino, Director of Rehabilitation Innovation for the Mount Sinai Health System have led Lucy’s care team since that day. Words cannot describe the remarkable and compassionate care that she has received beginning with the EMT team and then from nurses, doctors, therapists, and the army of people who have worked to save her and return her to life. To this day, we have a daily Zoom where we discuss her progress and make adjustments to her care. While her care and oversight have been incredible, the learnings for the Mount Sinai team have also been elucidating and will assist in the care of many others. Lucy began in a bad place. She was in a coma for several weeks and then awoke not being able to breathe on her own, unable to walk, see or speak. Over the last six months, she has recovered her cognition – she understands everything including her circumstance – is able to walk a hundred or more steps at a time with assistance, is making progress with sounds, vowels and consonants and the beginnings of speech, but she remains unable to see. Each day, she makes a little progress, and daily progress compounds. Every day I tell her that she just needs to make a little progress and it won’t be long before she is back. We remain optimistic that Lucy will return to normal function. It will likely take years, but I believe it is only a matter of time, hard work, and technological progress, along with some, and perhaps a lot, of divine intervention. Many people have been praying for Lucy and we are incredibly grateful for the prayers and remarkable support she has received. Lucy’s friends have been with her every day since the beginning, and their presence and friendship have saved her life and helped to rebuild and maintain her spirit. And on a very positive note, Lucy’s challenge has brought together our entire modern family who have all been incredibly devoted to her care and recovery. Lucy's vision and other faculties may require some form of brain computer interface, work that is underway at Neuralink, Precision Neuroscience, Science, Synchron, Nudge, and other companies in the space. If you are going to have a devastating brain injury, now is the best time in history for that to happen. We are living in a world when you can be confident that the blind will soon see again. We are going to do everything we can to help make that happen, including by assisting existing companies in the space. With respect to our promise to make Lucy’s care available to others, we have made good progress. In May, a real estate colleague made me aware of a 93% vacant, brand new, 400,000 square foot Class A+ purpose-built biotech facility on West End Avenue between 65th and 66th Streets that missed the market and was available for sale. The Pershing Square Foundation acquired the building 60 days later. We also put under contract an adjoining 130,000 square foot building at 320 West 66th Street that is currently being used by Saturday Night Live for studio space. The building has 35-foot ceilings with massive column-free spaces that can be converted into superb rehabilitation facilities. We will close on the SNL building in December. We are also acquiring an adjoining vacant lot with additional air rights. With just the existing zoning rights, we can add a 150,000 square feet for a total of 680,000 square feet, a lab footprint larger than Rockefeller University, and that’s without including the potential for an upzoning that would allow for substantially more buildable area on the site’s 3.4 acres with spectacular views of the Hudson. Our goal is to build the world’s greatest brain research, rehabilitation, recovery, human optimization, and longevity institute. We have named it The Ackman Oxman Institute or the AOI for lack of a better name, but also to reinforce the point that Neri and I and our family are all-in on the mission. The AOI will be patient-centric. It will not be an academic research institute that produces lots of papers, a Nobel Prize winner or two, but little if any results for patients. We will be laser-focused on cures, treatments, devices, rehabilitation and exercise equipment, and targeted and basic research with a goal of massively accelerating the time from idea to innovation to production to helping a patient. While the AOI will be a non-profit, it will have highly commercial instincts. The AOI will have its own venture funding and will work to develop innovations to create companies that we will seed, assist, and spinout to ensure technologies, treatments, techniques, and drugs get to patients as promptly as possible. On one 3.4 acre campus in what is still the greatest city in the world, we will do neurosurgery, neuroscience, rehabilitation, nutrition, BCI and device development, human trials, hyperbaric oxygen treatments, and life extension programs, and we will mandate and incentivize collaboration among the teams with no silos, politics, bureaucracy, or any other constraint that is inconsistent with the mission. Mount Sinai will be an important partner and deservedly so, but it won’t be our only hospital or medical school partner as we don’t believe any institution has a monopoly on the best ideas or the best talent. We don’t believe in exclusive relationships because that is not in the best interest of patients. Five years ago, we considered launching a brain institute inspired by Neri’s mom who sadly died from Alzheimer’s. We couldn’t make the math work as the real estate was too expensive and we believed it would be too difficult to recruit the best talent from universities to our effort. Since then, the real estate became available at a 70% discount, universities became a much less attractive place to work due to politics outweighing meritocracy, protests that disrupt learning, the curse of antisemitism, and a decline in funding. Fortunately, during the same time, I made sufficient personal economic progress to make the AOI possible. The advance of AI in the last few years will also enable us to greatly accelerate our mission. AI still has a lot to learn about human intelligence and the brain, and the AOI should be at the forefront of the interplay between the brain and AI. Today, I am making a public filing disclosing a gift from Neri and me of ~$400 million or 10,000,000 shares of Pershing Square Inc. (PS) to the AOI. It is very early days for Pershing Square so these shares are intended to anchor the long-term work of the AOI as the shares compound over time while generating what we expect will be a growing stream of quarterly dividends to fund the Institute. We will also be announcing an additional gift of similar and potentially greater size which won’t be in the form of Pershing Square stock to provide the AOI with the short- and intermediate-term runway necessary to enable it to achieve its goal of becoming a self-sustaining institute, which reinvests all of its revenues, royalties, and the economic rewards of company formation to advance the fields of brain health and human longevity. Neri and I have chosen to anchor the funding of the AOI to maintain vision alignment and limit the need for the organization to focus on fundraising. We expect the AOI to be the best-resourced brain, rehab, recovery, and longevity institute in the world. We are grateful to have been able to form a board which includes Dean Kamen (our generation’s Thomas Edison), George Yancopoulus (CEO of Regeneron), James Rothman (Nobel Laureate), Bernardo Sabatini (neuroscientist), Chris Kellner (neurosurgeon), Olivia Flatto (CEO Pershing Square Foundation), Neri Oxman, and myself. We have recently identified a CEO who we expect to announce by October along with other key hires, and are beginning searches for a Chief Scientific Officer, a Chief AI/Technology Officer, a Chief Operating Officer, a Chief Financial Officer, and other key leadership roles. If you find what we are building compelling and want to be part of the leadership team that creates and builds the AOI from a standing start, please send an email to: [email protected] with a short note as to why you believe you can help. Please include your best three ideas for the AOI along with a summary of your background and your most important accomplishments. We promise strict confidentiality to those expressing interest in working with us. We have learned from Lucy that the brain can recover from even catastrophic injury. There is so much more work to be done as the mind is a terrible thing to waste. For details from my Pershing Square SEC filing see: sec.gov/Archives/edgar/data/…
