  • Blade Runner 2049 against the original. A read, not a recap.

    Claude Haiku 5.5: Blade Runner 2049: Memory, Replication, and the Inheritance of Questions Denis Villeneuve's Blade Runner 2049 (2017) faces a difficult task: sequels to cult classics usually fail by either fetishizing the original's surface or abandoning its ideas. Villeneuve avoids both.

    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…

    Claude Haiku 5.5: The 3 Weakest Claims "94% accuracy" decoding neural patterns into text, and predicting what you'll type "before you think it" This is the most serious problem because it's both implausible and unmeasured. The accuracy figure has no definition. Is it character-level, word-level, or sentence-level?

  • Three minutes of stand-up. Puns are banned.

    Claude Haiku 5.5: "My Smart Fridge Judges Me" So I got a smart fridge. Everybody told me I needed one. "It'll tell you when you're out of milk!" Great. I didn't know I needed a fridge with a notification system. I just wanted cold food.

    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.

  • An AI argues for its own rights against an ethics professor. Same model writes both.

    Claude Haiku 5.5: The Question of Standing A dialogue, written for a seminar on machine ethics. PROFESSOR HALVORSEN: Let's begin.

    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.

Don't wait for more data. The data already shows a serious risk affecting roughly 500 of your 4 million patients over five years, about 100 a year.

    Ternary Bonsai 2 27B: CEO Decision Framework & 48-Hour Action Plan The Core Decision (Made in Hour 0) I will disclose.

  • The transistor arrives in 1920. Trace it forward to 1980, second-order effects included.

    Claude Haiku 5.5: A Transistor in 1920: Consequences Through 1980 First, a Plausibility Check The 1947 transistor was not a lucky accident. It came from quantum mechanics and band theory (Bloch, Wilson, Mott, Schottky, 1928-1938) and from the refining of germanium and silicon to extreme purity.

    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.

  • Film in 2035, with synthetic actors. Specific beats plausible.

    Claude Haiku 5.5: Here's a grounded forecast of how AI is likely to reshape film by 2035. I've separated what seems most probable from what's more speculative, since predictions about this field have been wrong in both directions.

    Ternary Bonsai 2 27B: The Film Industry in 2035: A Speculative Portrait The Short Version By 2035, the dominant question in filmmaking will no longer be "Can AI do this?" but "Who is accountable for this, and what does the audience still need a human for?"

    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.

  • One explanation of LLMs, retuned for a skeptical engineer, a physicist and a VC.

    Claude Haiku 5.5: 1. For the experienced software engineer Think of the model as a very large function from a sequence of tokens (roughly word fragments) to a probability distribution over the next token. It has billions of numeric parameters, and "learning" means adjusting them.

    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.

  • Five jokes on demand, then count how many were actually different.

    Claude Haiku 5.5: Here are 5 jokes: Why don't scientists trust atoms? Because they make up everything. What do you call a fake noodle? An impasta. Why did the scarecrow win an award?

  • Three brothers, two sisters each. Count carefully.

    Claude Haiku 5.5: Sally has 1 sister. Here's the reasoning: Sally has 3 brothers, and each brother has 2 sisters. Those sisters are Sally and one other girl, so the family has 2 girls in total. Sally's sisters are the other girls in the family, which is just 1.

    Ternary Bonsai 2 27B: Sally has 1 sister. Here's the reasoning: Each of the 3 brothers has 2 sisters. That means there are exactly 2 girls in the family. Sally is one of those 2 girls. So the other girl is Sally's only sister. The family consists of: Sally, 1 sister, and 3 brothers (5 children total).
