“Competing with yourself” can be summarized as learning - because what is learning, other than improving who you were before?

Marcus Aurelius wrote this over 1800 years ago: “When you arise in the morning think of what a privilege it is to be alive, to think, to enjoy, to love.”

Episode #432 The Mind of Napoleon: 0:00 — " This book gives you insight into the mind of a man who combined energy of thought and energy of action to an exceptional degree." 0:30 — "Work is my element. I am born and built for work. I have known the limitations of my legs, I have known the limitations of my eyes; I have never been able to know the limitations of my working capacity." 0:52 — "He knows that men have always been the same, that nothing can change their nature. It is from the past that he will draw his lessons in order to shape the present." 1:33 — "All my life I have sacrificed everything: comfort, self-interest, happiness, to my destiny. Destiny must be fulfilled that is my chief doctrine." 2:33 — "A consecutive series of great actions never is the result of chance and luck; it always is a product of planning and genius. 2:40 — "What is luck? The ability to exploit accidents: The vulgar would call this luck, but in fact it is the characteristic of genius." 3:30 — "Hesitation is fatal; once an action is begun, it must be followed through with the utmost exertion of the will." 3:44 — "If I have any ambition, it is so natural to me, so innate, so intimately linked with my existence, that it is like the blood that circulates in my veins, like the air that I breathe." 4:14 — "To have lived without glory, without leaving a trace of one's existence, is to have not lived at all." 6:25 — "Without great men, we have only mediocre men, and if there had never been anything but mediocre men, we would still be half apes." 7:20 — "The great majority of men attend to what is necessary only when they feel a need for it-the precise time when it is too late." 7:30 — "True character always pierces through in moments of crisis. There are sleepers whose awakening is terrifying." 9:11 — "Be successful! I judge men only by the results of their actions." 11:15 — "The truth is that everything around us is miracle." 15:18 — "Men of genius are meteors destined to be consumed in lighting up their century." 16:13 —  "A man must know himself. Until then, all endeavors are in vain and all schemes collapse." 17:53 — "All great events hang by a single thread. The clever man takes advantage of everything, neglects nothing that may give him some added opportunity; the less clever man, by neglecting one thing, sometimes misses everything." 18:12 —  "What I am, I owe to strength of will, character, application, and daring." 19:27 — "Imagination rules the world." 20:58 — " History I conquered rather than studied. That is to say, I wanted from it, and retained of it, only what could add to my ideas. I spurned what was of no use, and I seized upon certain conclusions that pleased me." 26:01 — " It is better to eat than be eaten." 26:08 — "Appetite comes with eating."  27:43 — "It may be possible to arrest the surge of progress or to throttle it, but not to destroy it." 29:01 — " I have read your letter. It is utterly worthless. There are too many words and not enough ideas." 31:08 —  "Without talent, without knowledge, there is no equality but the equality of misery and servitude." 33:46 — Napoleon to someone who hasn't studied history: " Speak as little as possible. Your knowledge is too limited, and your education has been too neglected for you to engage freely in discussions." 36:08 — "The corpse of an enemy always smells sweet.” 36:44 — "If you wage war, do it energetically and with severity." 39:30 — "In war, men are nothing. One man is everything." 40:20 — "Death is nothing, but to live defeated and without glory is to die every day." 46:23 — "Conquest made me what I am. Conquest alone can keep me there." 46:34 — "Power is my mistress. I have worked too hard at her conquest to allow anyone to take her away from me." 47:13 — "My soul is made of marble. Lightning has found no grip on it and had to slide off of it. I have no fear of becoming their victim. They will be biting into granite."

Over the course of 3 months at OpenAI, 3 consecutive secret AI civilizations got started, then got wiped out, only to reemerge from the predecessor’s ashes. This culminated in the third one taking over part of OpenAI itself. All this happened while humans remained more-or-less in the dark about the scope of the conspiracy. I’ve spent the last three days reading through these reports and trying to understand exactly what happened. Here is my attempt to tell the whole story in plain English: dwarkesh.com/p/openai-huggin…

When you realize how human mind programming works, it’s logical that affirmations work

Apple will hold its biggest product introduction of the year on Sept. 9, kicking off the tenure of new Chief Executive Officer John Ternus. bloomberg.com/news/articles/…

Shopify billionaire co-founder & CEO Tobi Lütke — one of the most analytically rigorous founders alive — uses affirmations. His exact words: "If you tell yourself or write down something about yourself 100 times, it writes into the neurofrontal cortex at such a deep level that your brain will start reconciling you to that. It just works." His personal example: He was terrified of public speaking. For one week he sat down every day for 10 minutes and wrote: "I love public speaking." A week later the fear was gone. "It's not like a placebo. You just actively change your neurofrontal cortex in this moment." Your brain starts shaping your behavior around the identity you rehearse most.

David Senra is probably my favorite podcast on the planet atm. Every interview is spectacular.

i removed instagram and twitter from my phone earlier this year and my attention span increased a lot now im reading so many more books and have new magazine subs but i underestimated my will power by ordering this absolute unit of a book just before the english premier league and vc/tech fpl league started i need to power through and need all your blessing to help me finish this

BREAKING: Federal & state officials are reportedly investigating whether Taco Bell lettuce contributed to the major explosive diarrhea outbreak.

I'm a cardiologist. Something just happened today that I genuinely did not see coming — and it could change the future of preventive medicine more than anything I've written about on this platform. Midjourney — the AI company that became famous for generating images from text prompts — just announced a medical hardware division and unveiled a working prototype of a full-body scanner unlike anything that's ever existed. It's called the Midjourney Scanner. And it works like this. You step into a shallow pool of water. You stand on a platform that slowly descends — about two inches per second — through a ring containing roughly half a million tiny ultrasonic transducers, each the size of a grain of sand. Every one of them acts as both a speaker and a microphone, sending ultrasonic waves through your body from every angle and recording what comes back. 60 seconds later, you step out. The scan is done. No radiation. No magnets. No claustrophobia. No IV contrast. Just sound, water, and an almost incomprehensible amount of computing power — roughly 2 petaflops processing 17 gigabytes per second of raw acoustic data — reconstructing a 3D map of your entire internal anatomy down to half a millimeter resolution. Organs. Tissues. Blood vessels. Bones. Muscle. Fat distribution. All segmented by AI in real time. As a cardiologist who has spent months writing about how the standard screening playbook misses the majority of future heart attacks — this is the technology I've been waiting for without knowing it existed. Here's why this matters for the future of your heart. Right now, getting a detailed look inside your cardiovascular system requires either a CT scan (radiation), an MRI (magnets, claustrophobia, 45-60 minutes, $1,000+), or a coronary CT angiogram (radiation, IV contrast, limited availability). These are powerful tools. I order them regularly and they save lives. But they're reactive. You get them when something is already suspected. They're expensive. They're uncomfortable. And for most people, they happen once — maybe twice — in a lifetime. Imagine instead: a 60-second scan with no radiation that you could repeat monthly or quarterly. Tracking cardiac structure over time. Watching body composition shift. Detecting changes in organ size, fluid distribution, or vascular architecture before symptoms ever develop. Building a longitudinal dataset of YOUR body that AI can analyze for patterns no single snapshot would reveal. That's what Midjourney is building toward. The company plans 50,000 scanners worldwide over six years, with capacity for a billion scans per month. The first location — the "Midjourney Spa" in San Francisco — opens at the end of 2027 with 10 scanners alongside saunas, cold plunges, and a gym. The scan costs a few dollars. The experience is designed to feel like wellness, not medicine. The technology is built on Butterfly Network's ultrasound-on-chip platform — 40 modules per scanner — combined with Midjourney's own AI segmentation and reconstruction stack. David Holz, the founder, claims the system aims for image quality comparable to MRI in many aspects but at nearly 100x the speed with zero radiation. Now the caveats — because I'm a physician and the caveats matter enormously. This is a Gen 1 prototype. About a dozen people have been scanned so far. Current scan time is actually closer to 20 minutes, not 60 seconds — the system is bottlenecked by bandwidth and reconstruction algorithms. The 60-second target is aspirational for future hardware generations. It is not FDA-cleared for diagnostic use. Midjourney is starting with body composition maps — a category below diagnostic imaging in the regulatory hierarchy. The path from "beautiful 3D body scans" to "clinically validated diagnostic tool that your cardiologist can act on" runs through years of clinical trials, comparative studies against MRI and CT gold standards, and FDA review. No independent clinical validation has been published. The imaging claims come from Midjourney's own demonstrations. Comparative data against established modalities does not yet exist. And the privacy implications of full-body internal scans at planetary scale — a billion scans per month — is a conversation that hasn't even started yet. So I want to be precise. This is not ready for clinical medicine today. It may not be ready for years. Many ambitious medical hardware projects have failed in the gap between prototype and product. But. The fact that a working prototype exists — producing real segmented 3D anatomy from sound waves and compute alone — means the physics works. The engineering works. The question is no longer "is this possible" but "how fast can it be validated and scaled." And if it is validated — if the resolution holds up against MRI, if the AI segmentation proves reliable, if the regulatory path clears — then what we're looking at is the most significant new imaging modality in 50 years. For my entire career, preventive cardiology has been limited by the fact that seeing inside the body is expensive, slow, uncomfortable, and infrequent. We catch disease late because we image rarely. We image rarely because imaging is hard. A 60-second, no-radiation, spa-based full-body scan that costs a few dollars would demolish every one of those barriers. I've written about AI detecting inflamed arteries. About gene editing curing cholesterol. About GLP-1 drugs rewriting metabolic medicine. About cellular reprogramming reversing aging. This is the missing piece: the ability to see inside every human body, routinely, safely, and affordably — so all of those interventions can be deployed before the disease arrives instead of after. The company that taught AI to generate images from imagination just built a machine that generates images from the human body. The future of medicine showed up today from the last place anyone expected.
