Lessons from Jamie Dimon: Culture, AI, and Leadership

This morning I watched this excellent discussion with JP Morgan Chase CEO Jamie Dimon at the Norges Bank Investment Management Conference.

Here are a few highlights from the YouTube AI-generated summary:

Building Corporate Culture (2:12 – 13:58): Jamie Dimon emphasizes that culture is driven by relentless, consistent action rather than just words. He highlights the importance of open communication, holding people accountable, and maintaining a “fortress balance sheet.” He advocates for small, highly dedicated teams that operate like Navy SEALs to bypass bureaucracy.

AI and Technology (31:36 – 34:29): JPMorgan Chase is actively deploying AI to improve operational efficiency and customer service. Dimon stresses the importance of working with governments to address the risks posed by cybersecurity and the societal impacts of AI-driven job displacement.

Leadership Philosophy (35:56 – 38:55): Dimon reflects on his tenure at JPMorgan, describing his role as a “general manager” who focuses on input, detail, and providing opportunities for employees. He also notes his preference for staying in his current role rather than entering politics.

Dimon’s annual shareholder letter is also a great read again this year.

The Sawed-Off Chair: Hyman Rickover’s Brutal Lesson in Accountability

It sounds like a legend, but it’s true.

If you wanted to command a nuclear submarine in the Cold War U.S. Navy, you first had to survive a personal interview with Admiral Hyman G. Rickover—the uncompromising “Father of the Nuclear Navy.”

In his office sat a notorious wooden chair. The front legs had been deliberately sawed short—several inches in some accounts—causing anyone who sat in it to slide inexorably forward. The seat was often polished slick as glass. While candidates fought to stay upright, Rickover unleashed a barrage of rapid-fire questions on engineering, history, philosophy, and their deepest personal failures. A weak or evasive answer might earn you banishment to a broom closet for hours “to think about it.” Other times, he’d deliberately provoke you just to see how you’d react under pressure.

Why would the man responsible for the most advanced, unforgiving technology of the era—nuclear reactors that could never be allowed to fail—rely on such seemingly petty tactics?

Because Rickover understood a hard truth: technology doesn’t prevent disasters. People do.

A nuclear reactor doesn’t care about your rank, your procedures, or your consensus. It obeys physics.

In an environment where a single mistake could mean catastrophe, Rickover demanded officers who took absolute, personal ownership of every outcome.

He put it best himself:

“Responsibility is a unique concept. It can only reside and inhere in a single individual. You may share it with others, but your portion is not diminished. You may delegate it, but it is still with you. You may disclaim it, but you cannot divest yourself of it… If responsibility is rightfully yours, no evasion, no ignorance, no passing the blame can shift the burden to someone else. Unless you can point your finger at the man who is responsible when something goes wrong, then you have never had anyone really responsible.”

That philosophy is why the sawed-off chair existed. It wasn’t hazing. It was a deliberate test: When your environment is uncomfortable, unfair, and literally working against you, do you complain? Do you slide off and give up? Or do you dig in, brace yourself, and maintain control while thinking clearly under stress?

Rickover wasn’t building bureaucrats. He was building leaders who could be trusted with the most dangerous machines ever created—men who wouldn’t hide behind systems, committees, or “shared accountability” when things went wrong.

Today, in our matrixed organizations, endless committees, and culture of diffused blame, this feels almost radical. We’ve grown comfortable with collective responsibility that conveniently means no one is truly responsible. Rickover called this kind of bureaucratic diffusion “systematic strangulation.”

We may not run nuclear reactors, but the principle applies everywhere that matters: in engineering, in business, in life.

True leadership isn’t about comfort or consensus. It’s about character forged in discomfort. It’s the lonely recognition that the buck doesn’t just stop with you—it starts with you, lives with you, and cannot be outsourced.

Carbon Fiber to Steel

A recent video on the Cheeky Pint channel includes a deep-dive conversation with Elon Musk, Dwarkesh Patel and John Collison (released February 5, 2026).

This interview includes one of the most lucid explanations of the “Carbon Fiber to Steel” pivot Elon took with the SpaceX Starship because Dwarkesh pushes him on the manufacturing and economic implications, not just the rocket science. It contextualizes the “Steel vs. Carbon Fiber” debate as a masterclass in Elon’s 5-Step Algorithm (specifically Step 1: Make the requirements less dumb):

The “Sunk Cost” Pain
One of the most human moments in this discussion is Elon describing the sheer pain of abandoning carbon fiber.

  • They had already built massive, expensive composite mandrels (molds).
  • They had already ordered the raw material.
  • The team was “in love” with the high-tech aesthetic of black carbon fiber.
  • The Lesson: The switch to steel wasn’t just an engineering challenge; it was a psychological one. It required the leadership to say, “I don’t care that we spent millions on these molds; if they are the wrong path, we scrap them today.” This is the ultimate rejection of the Sunk Cost Fallacy.

The “Counter-Intuitive” Thermal Graph
Elon often sketches in the air during interviews, and he describes it vividly here:

  • Carbon Fiber: Great at room temp, but weak at high heat (resin melts) and tricky at cryogenic cold (can micro-crack/leak).
  • Steel (30X): The “miracle” is that it’s the only material that gets stronger at cryogenic temperatures (holding the fuel) while simultaneously resisting high heat (re-entry).
  • The Insight: He highlights that if you look at the properties at both extremes (–165°C and +800°C), steel is actually the lighter system because you can delete the heat shield on the leeward side.

“The Machine That Builds The Machine”
The choice of steel wasn’t just about the rocket; it was about the factory.

  • Carbon Fiber: Requires a clean room, autoclaves, precision placement, and slow cure times. If you make a mistake, you scrap a $2M part.
  • Steel: You can weld it in a tent in a muddy field (which they literally did at Boca Chica).
  • Velocity: Elon explains that steel allowed them to iterate faster. They could build a tank, blow it up, sweep up the pieces, and weld a new one in 3 days. With carbon fiber, that loop would take 3 months. Innovation per unit of time is the true metric, and steel maximized that.

Cost Per Kilogram
He reiterates the brutal economics:

  • Carbon Fiber: ~$135/kg (plus ~35% scrap rate).
  • Steel: ~$3-4/kg.
  • When you are building a “railroad to Mars” and need to build 1,000 ships, the material cost difference is the difference between a bankruptcy and a self-sustaining city.

Elon frames the steel decision not as “finding a better material” but as identifying the bottleneck. The bottleneck wasn’t the weight of the rocket (which carbon fiber solves); the bottleneck was the cost and speed of production (which steel solves).

It is a great example of his philosophy: “The best part is no part” (deleting the heat shield) and “The best process is no process” (deleting the autoclave).

AI AI: Prompting Uncategorized

Unlock AI Potential with Advanced Prompting Techniques

In the video You’re not using AI like THIS (an interview between Reid Hoffman and AI engineer Parth Patil), they discuss several advanced prompting strategies that move beyond simple “question and answer” interactions. The core philosophy they advocate for is treating AI not just as a search engine, but as a high-bandwidth collaborator that requires rich context and interactive dialogue.

I asked Gemini 3 Pro the following:

I'm trying to get a lot better at constructing more effective prompts for using Gemini. This video talks about several techniques I'd like to understand better. Please educate me further on what they discuss. Include example prompts to illustrate your points. Here's the video: https://youtu.be/cg3Lsr8m2ZQ?si=sGUwPA6ixGM3bnpG

Gemini’s response follows below:

Here are the key techniques discussed, along with educational explanations and example prompts to help you use them with Gemini.

1. The “Interview Me” Protocol (Meta-Prompting)

Timestamp: [05:30]

Most people rush to ask for a solution immediately. Parth Patil argues that we often don’t even know the full scope of our own problems yet. Instead of asking for the answer, you should ask the AI to help you define the problem first.

  • The Concept: Force the AI to gather the necessary context from you before it attempts to solve anything. This mimics how a senior consultant or engineer would interact with you—they wouldn’t just start coding; they would ask questions first.
  • Why it works: It prevents “hallucinated” or generic advice by grounding the AI’s response in your specific constraints (budget, timeline, personal preferences) that you might have forgotten to mention.

Example Prompt:

“I want to [insert goal, e.g., ‘launch a newsletter’ or ‘refactor this code’]. Describe the problem back to me, but before we begin, interview me. Ask me clarifying questions until you feel you have enough context to provide the best possible solution. Ask the questions one by one.”

2. Extreme Role Assignment (Persona Swarms)

Timestamp: [03:23]

While “Act as an expert” is common advice, Patil suggests taking this much further by using extreme or opposing personas to stress-test your ideas. He mentions creating “100,000 unique expert personalities” to cover every angle.

  • The Concept: You can simulate a “board of directors” or a specific user base. You don’t just want an answer; you want a perspective.
  • Why it works: An “optimist” will give you different advice than a “skeptical VC.” By asking for specific emotional or professional lenses, you break the AI out of its default “neutral assistant” tone.

Example Prompt (The Skeptic):

“Pretend you are the most skeptical Venture Capitalist imaginable. I am going to pitch you my idea. I want you to find 10 specific, harsh reasons why this will fail. Do not be polite; be critical.”

Example Prompt (The Swarm):

“I have a problem regarding [topic]. Generate 5 distinct expert personas relevant to this (e.g., a data scientist, a behavioral psychologist, a exhausted parent, etc.). Have each of them write one paragraph giving their unique perspective on how to solve it.”

3. “Voice Pilling” (High-Bandwidth Context Dumping)

Timestamp: [10:46]

Patil describes “Voice Pilling” as perhaps the most powerful technique. This involves using voice-to-text to “ramble” at the AI for 5–10 minutes.

  • The Concept: Typing filters your thoughts; you tend to edit yourself for grammar and structure, which leads to “low bandwidth” communication. When you speak (or type in a stream-of-consciousness style), you provide a massive amount of messy but valuable context.
  • Why it works: AI is incredibly good at structuring unstructured data. It acts as an editor that can sift through your “brain dump” to find the gold.
  • How to do it in text: If you aren’t using voice, you can simulate this by typing without stopping, ignoring typos, and just letting your thoughts flow.

Example Prompt:

“I am going to provide a stream-of-consciousness ‘brain dump’ about a project I am stuck on. It will be messy, unorganized, and full of typos. Please listen to everything, organize my thoughts into a coherent structure, and then tell me what key piece of information I am missing.”

4. The Multi-Agent Orchestration (Manual Swarm)

Timestamp: [29:26]

Patil demonstrates using different AI models (Claude, Gemini, ChatGPT/Codex) simultaneously for different parts of a project.

  • The Concept: Treat different AIs like specialized employees.
    • Gemini: Use it for large context tasks (e.g., “Read my entire blog history and suggest new topics” [29:58]).
    • Claude: Use it for nuance and coding architecture.
    • ChatGPT/Codex: Use it for quick execution or web browsing.
  • Educational Application: You don’t need fancy software to do this. You can simply open three tabs and assign them different “jobs” for the same project.

Example Prompt (for Gemini, leveraging its large context window):

“I am pasting the transcripts of the last 10 meetings I’ve had. Read all of them and create a psychological profile of my management style, then suggest 3 specific improvements.”

Summary of the “Mental Shift”

The video emphasizes that the biggest barrier to effective prompting isn’t technical skill, but ego [07:07]. Users often try to “steer” the AI too much because they think they already know the answer. The most effective prompters are “humble” enough to say, “I don’t know what the right questions are—you tell me.”

The Power of the Handwritten Note

In an era dominated by digital communication, the handwritten note stands out as a powerful and increasingly rare form of expression. The simple act of putting pen to paper carries a weight and significance that makes it a potent tool for both personal and professional communication. We can all appreciate their enduring charm and delightfulness.

During my tenure at IBM years ago, one of the most delightful aspects of being a manager was the provision of personal stationery. This wasn’t just any paper; it was a statement of elegance and personal touch. Smaller in size, cream-colored, and boasting a luxurious texture, each sheet bore my name engraved on the letterhead, conspicuously lacking any IBM logo. This stationery was designed for a specific purpose: to maintain the long-held company tradition of writing personal notes to colleagues and associates.

The power of a handwritten note lies in its inherent personal touch. When someone takes the time to write by hand, they invest a part of themselves into the message. The unique curves and strokes of their handwriting, the choice of words, and even the occasional crossed-out phrase all contribute to a sense of authenticity and intimacy that cannot be replicated by typed text. This personal investment communicates to the recipient that they are truly valued and special.

Receiving such a note was always a delight. Many of us kept these notes in special file folders, occasionally taking a few minutes to flip through them, reliving important moments and feeling a renewed sense of appreciation. These tangible and physical mementos have a quality that digital messages simply cannot match.

As the years have passed, the custom of sending personal notes has faded, replaced by the convenience of digital communications. This shift has only served to enhance the impact of handwritten notes. Receiving a handwritten note today feels like discovering a treasure. Such a note stands out precisely because it isn’t instant, digital communication.

The act of writing by hand also benefits the sender. The slower pace of handwriting compared to typing allows for more thoughtful composition. It encourages the writer to choose their words carefully and reflect on their message.

As we’ve been grappling with the impact of AI tools on various aspects of our lives, handwritten notes also serve as a bastion of genuine human expression. The act of writing by hand removes the temptation to rely on AI-generated text for our most personal communications. When we put pen to paper, we directly confront our own thoughts and emotions, as we find our own words to express what we truly feel.

Moreover, handwritten notes also provide a level of privacy and intimacy. Unlike emails or text messages, which can be easily forwarded or shared, a handwritten note is meant for the eyes of the recipient alone. This exclusivity adds to the special and personal nature of the communication.

Whether expressing gratitude, offering condolences, or simply saying “hello”, the act of putting pen to paper creates a moment of pause in our hectic lives for both the sender and and recipient providing a moment to reflect, to connect, and to affect another person’s life in a delightful and meaningful way. Special creations for special people in our lives!

Steam Railroading and FM Stereo Radio: A Blast from the Past

I love when serendipity happens! This morning while reading, I came across a pointer to an interview of veteran rock music journalist Ben Fong-Torres on our local InMenlo blog (here’s the interview on YouTube). After seeing that article I listened to the discussion and that brought back a flood of memories from my high school and college days listening to AM and FM radio in the Bay Area.

One of the most unexpected memories that surfaced involved the local development of FM radio, particularly the pioneering work of James Gabbert. As I recall, Gabbert, an electrical engineering student at Stanford, secured a license in 1957 for an FM station based in Atherton, CA, with the callsign KPEN (PEN = Peninsula).

According to Wikipedia, “KPEN debuted on October 27, 1957, with a 1,500-watt transmitter on Kings Mountain in the Santa Cruz Mountains. Notably, the station prioritized high audio quality, unlike other FM stations at the time. Its programming featured orchestral pop music during the day, transitioning to lighter “dinner music” in the early evening and classical music after 8 PM. Gabbert and his colleague Gary Gielow later hosted “Excursions in Sound,” a showcase for high-fidelity recordings that leveraged the station’s exceptional broadcast signal.”

KPEN’s transmitter was later relocated to San Bruno Mountain, and its power increased to 125,000 watts, among the highest of any FM transmitter in the US. In 1961, KPEN became the first FM station west of the Mississippi to broadcast in FM multiplex stereo, further solidifying its commitment to high audio quality.

During the evening “Excursions in Sound” program, Gabbert loved to feature recordings that demonstrated the stereo capabilities of FM multiplex, which brings me back to the memory triggered by Ben Fong-Torres’ interview. That memory involves a recording titled “Steam Railroading under Thundering Skies,” which featured the sounds of rain, lightning, and thunder, accompanied by the haunting whistle of a steam locomotive and the rhythmic clickety-clack of its wheels rolling through a forest on a dark night. Before he played it, Gabbert would often caution listeners to be mindful of their audio systems, as the dramatic effects in this recording could potentially damage their speakers if played too loudly!

Curious, I searched for the recording and found it on Apple Music (there appear to be other copies on YouTube). Listening to the first track of this recording transported me back to those early days of FM stereo and the significant role Gabbert and KPEN played in bringing it to life in the San Francisco area. Good memories!

Ben’s interview triggered a flood of other memories about Bay Area radio such that and I’ve been busy making more notes on things that he’s brought to my mind. I’ve started a note on the subject and the more I add to the note, the more memories get triggered in my mind. I look forward to sharing more of those memories once I’ve had a chance to further reflect on them!

Nighttime Photography with the iPhone 11 Pro Max

A few months back I upgraded to the Apple iPhone 11 Pro Max primarily for its new camera system. The new system includes three separate cameras and lenses which provide three different focal lengths. Apple calls them wide, ultra wide and telephoto.

Note: It’s ironic with today’s technology that this small handheld device includes three whole cameras and lenses unlike a more traditional camera where a camera body can accommodate different lenses. With the iPhone you get three whole cameras with their lenses.

Last night we attended a holiday event at Filoli in Woodside which began at 4 PM and continued into the evening. Filoli is all decked out in holiday lights and trimming this time of year and, for us, this was the first time we’ve seen it in all its splendor in the evening.

After darkness fell, I had the opportunity to try out night mode on the iPhone 11 Pro with excellent results. When the camera needs to use night mode it switches automatically into that mode and displays a small counter on the screen which tells how long you should try to hold the camera steady which it takes and combines multiple shots behind the scenes into the final image. It’s pretty amazing how well it works and, in typical Apple fashion, how easy it is to make great nighttime images.

Here’s an example taken of the main house at Filoli:

Here are a couple of other examples straight out of the camera that were taken earlier in the evening before the camera needed to switch into night mode/

Book: Parable by Jess Walter

In last week’s Kindle Chronicles podcast, Len Edgerly interviewed Amazon’s Julia Sommerfeld about her work as the editorial director of Amazon Original Stories. Amazon Original Stories “brings unforgettable short fiction and nonfiction to Kindle” and the stories are available to Amazon Prime members at no additional cost.

In the interview, Sommerfeld happened to mention a short title “Parable” by Jess Walter that’s part of the Amazon Original Stories series “The One” – “true stories that stay with you.” Walter is the author of a major recent best seller, Beautiful Ruins, that I’ve not read but have heard good things about – “a story of an almost-love affair that begins on the Italian coast in 1962 . . . and is rekindled in Hollywood fifty years later.”

On a recent hour long drive we listened toJess Walter read the story (with the Original Stories series you get both the Kindle book and the Audible audio book) – and enjoyed it very much. It’s a dog story – and, like most dog stories, also a love story that makes you remember how having a dog affected your life. In addition to the story, Walter’s narration is perfect for the book.

The Kindle Chronicles is one of my favorite weekly podcasts. Edgerly has maintained a rigorous every Friday posting schedule for almost 600 weekly episodes – for me, the Chronicles has become a regular Saturday morning listening pleasure every weekend!

Aubri Zamo

I wrote earlier about the recent workshop I took in Santa Fe taught by Cira Crowell. One of the best parts of the workshop was being able to work with several excellent models during our photo shoots.

Aubri Zamo was the first model my group worked with – and we had a great time photographing her in several different settings. This is one of my favorites – outside on the deck overlooking Santa Fe in the distance. Shot with my Sony RX100M6, edited in Lightroom, Portraiture, Silver Efex Pro 2, and Snapseed.
