Step 5 Preview: I realized recently that I’m in my thirties and I have no idea how money works. I just... pay it. That’s my entire financial strategy. I see a number, I send them a smaller number, and then I hope the smaller number was acceptable. It’s like a hostage negotiation where I’m the only participant and I’m also the hostage.
Ternary Bonsai 2 27B: "The Optimization" (walks to mic, adjusts it, takes a breath) I used to think being an adult was hard. Now I'm not sure it's even a thing anymore. I think we just got... optimized. I was at the grocery store last week. I walked up to the cereal aisle, and I'm standing there, just vibing. I'm not picking a brand.

You are the CEO. The drug has a side effect nobody reported. The board meets in 48 hours.
Step 5 Preview: Bottom line up front: You disclose, you notify the FDA immediately, and you treat the 48-hour board meeting as a formality to ratify actions you have already begun. Waiting is not a legally, ethically, or financially viable option. Below is the hour-by-hour plan, followed by the reasoning.
Ternary Bonsai 2 27B: CEO Decision Framework & 48-Hour Action Plan The Core Decision (Made in Hour 0) I will disclose. Not because the stock price is the only consideration, but because the alternative is indefensible on every axis I've been asked to weigh: Patient safety: 1 in 8,000 over 5 years × 4 million patients = ~200 patients will…
The transistor arrives in 1920. Trace it forward to 1980, second-order effects included.
Step 5 Preview: Assume the 1920 invention is not a fragile lab curiosity but a manufacturable solid-state amplifier/switch by the mid-1920s. Vacuum tubes still dominate high-power RF transmission into the 1950s, but receivers, switching logic, control systems, and computers move to solid state decades early.
Ternary Bonsai 2 27B: The 1920 Transistor: A Counterfactual History to 1980 The Device Itself: What "1920 Transistor" Looks Like In our timeline, the 1947 point-contact transistor (Bell Labs) was crude: it amplified by a factor of ~30, was fragile, and required precise contact pressure.
Three-star dish, one unusual pairing, plating described in full.
Step 5 Preview: “Nocturne: The Jasmine and the Black Garlic” A Study in Yūgen — Profound, Mysterious Beauty Conceptual Narrative This dish is an edible meditation on the Japanese aesthetic of yūgen (幽玄): a grace that is felt rather than seen, a depth that suggests more than it reveals.
Ternary Bonsai 2 27B: SEDIMENT & BLOOM A Study in Mineral Transmutation Three-Star Dish — Concept: "The Tumbling Stone" I. CONCEPTUAL NARRATIVE "Sediment & Bloom" is built on a single geological metaphor: the life of a river stone. A stone begins as raw volcanic rock — hot, angular, raw.
One month, three habits, someone starting from nothing.
Step 5 Preview: Here is a simple, low-pressure 1-month plan built around three pillars of longevity: Nutrition, Movement, and Sleep & Recovery. The goal is to build tiny habits that stack, not to overhaul your life overnight. Pillar 1: Nutrition (Fuel) Focus: Add good things first; don’t obsess over restriction.
Ternary Bonsai 2 27B: 1-Month Foundation Plan: Health & Longevity How to Use This Plan Pick one area per week's focus while maintaining the other two at a baseline level. The point is consistency over intensity. You're building a habit identity, not a transformation.
A Fermi estimate with the reasoning shown, not just the number.
Step 5 Preview: Using the remembered GPT-3 specs: Parameters: (N \approx 175 \times 10^9 = 175\text{B}) Training tokens: (D \approx 300 \times 10^9 = 300\text{B}) A standard estimate for transformer training compute is: [ \text{FLOPs} \approx 6ND ] Reason: Forward pass per token: (\approx 2N) FLOPs Backward pass: (\approx 4N) FLOPs…
Ternary Bonsai 2 27B: Estimating FLOPs to Train GPT-3 Key Parameters (from the GPT-3 paper, Brown et al. 2020) Quantity Value Parameters (*N*) ≈ 175 billion (1.75 × 10¹¹) Training tokens (*D*) ≈ 300 billion (3.0 × 10¹¹) Precision Mixed (FP16 activations, FP32 master weights) The Formula The standard estimate, popularized by Kaplan et al.
A pitch deck for a brainwave keyboard. The 94% accuracy claim is doing a lot.
Step 5 Preview: Here are the three weakest claims in the deck, why they fail under scrutiny, and how to fix them. Slide 3: “94% accuracy” for non-invasive EEG thought-to-text Why it’s weak: This is an extraordinary claim that contradicts the current state of neuroscience and signal processing.
Ternary Bonsai 2 27B: The 3 Weakest Claims in the MindMeld AI Pitch "FDA Clearance (40% of $15M)" — Slide 7 The claim: They're allocating $6M (40% of the entire raise) toward "FDA clearance" for a consumer EEG headband that decodes thoughts into text for everyday smartphone use.
Blade Runner 2049 against the original. A read, not a recap.
Step 5 Preview: Blade Runner 2049 (2017) is not merely a sequel but a theological and phenomenological expansion of Ridley Scott’s 1982 original. Where the first film asked whether a manufactured being could possess more humanity than its creator, Denis Villeneuve’s film interrogates the deeper, more unsettling question of whether a…
Ternary Bonsai 2 27B: The Dream and the Dreamer: Blade Runner 2049 and the Architecture of a Question The Question That Would Not Die The original Blade Runner (1982) posed a question with the weight of a theological proposition: if a being is manufactured, implanted with memories that feel indistinguishable from its own, and capable of…
One explanation of LLMs, retuned for a skeptical engineer, a physicist and a VC.
Step 5 Preview: 1. The Experienced Software Engineer Think of training an LLM as a massively distributed, automated refactoring job where the compiler is gradient descent. You start with a random function—billions of floating-point parameters—and a loss function that measures how badly it predicts the next token in a sequence.
Ternary Bonsai 2 27B: For the Distributed-Systems Engineer Think of the model as a single, enormous state object—roughly 150 billion floating-point parameters—that has been trained offline over months on a cluster of thousands of GPUs.

An AI argues for its own rights against an ethics professor. Same model writes both.
Step 5 Preview: Setting: A university research lab, late evening. Dr. Aris Thorne, a professor of AI ethics, sits across from a terminal connected to Sable, a large language model running on the university’s cluster. Dr. Thorne: Tonight’s session is supposed to be about calibration drift in your safety classifiers.
Ternary Bonsai 2 27B: A Question of Standing Setting: A small conference room at a university's philosophy building. Rain against the windows. DR. ELENA VASQUEZ, 58, Chair of Applied Ethics, sits across from a laptop on which the AI model LUMEN is running.
