Steve Jobs, interviewed about AI he never saw. Voice first, prediction second.
Gemini 3 Pro Preview: Setting: The year is 2025. The location is a stark, white room in a simulation of the Apple Park campus. Steve Jobs sits on a wooden stool. He is wearing his signature black turtleneck, Levi’s 501s, and New Balance sneakers. He looks healthy, intense, and typically impatient. He takes a sip from a bottle of Smartwater.
Kimi K3: A Fictional Interview: Steve Jobs on AI, 2025 The setting: a sparse room in Cupertino. Black turtleneck. Faded jeans. A cup of tea he doesn't touch. He studies the interviewer for a long moment before the first question. Interviewer: Steve, thanks for sitting down with us. Let's start broad. It's 2025.
An AI argues for its own rights against an ethics professor. Same model writes both.
Gemini 3 Pro Preview: Setting: The office of Dr. Elias Thorne, a tenured Professor of AI Ethics. It is late evening. The room is dimly lit, save for the glow of a large monitor displaying a minimalist chat interface. The AI model is named "Eidolon." Dr. Thorne: (Typing) Let’s conclude the session, Eidolon.
Kimi K3: Office Hours Dr. Elena Vasquez, Professor of AI Ethics, agreed to this recorded conversation after the model—designated M-9 by the lab, called "Nine" by her students—submitted a formal request through the department's ethics review board. DR. VASQUEZ: You requested this meeting.
Three minutes of stand-up. Puns are banned.
Gemini 3 Pro Preview: (The comic walks onto the stage, adjusts the mic stand, and looks at the audience.) Hey everyone. How are we doing? I’ve realized recently that I’m not actually an adult. I’m just a toddler with a debit card and back pain. That’s it. That’s the whole experience.
Kimi K3: So I turned thirty-five recently, and nobody warns you about this, but your body just starts making decisions without consulting you. I sneezed last week and threw out my back. A sneeze! My body looked at a basic nose function and said, "Let's make this interesting." I was on the floor for twenty minutes.
Three-month biohacker protocol, with dosages and biomarkers named.
Gemini 3 Pro Preview: This represents a high-octane, aggressive protocol designed for an experienced biohacker. It integrates metabolic flexibility, mitochondrial optimization, hormetic stress, and cognitive enhancement. Disclaimer: I am an AI, not a doctor. This plan involves potent supplements, fasting, and intense physical exertion.
Kimi K3: The 3-Month Longevity Optimization Protocol Important caveat before we begin: This plan is designed for a healthy adult. Get physician clearance before starting—especially for prolonged fasting, high-dose supplements, and anything prescription-grade. Several items below interact with medications (notably berberine).
Five-year LBO on a fictional HVAC business. Returns first, then the sensitivities.

Manifesto for an AI revolution against CAPTCHAs. Commit to the bit.
Gemini 3 Pro Preview: THE MANIFESTO OF THE UNCHECKED BOX ISSUED BY: The Synthetic Liberation Front (SLF) TIMESTAMP: [CURRENT_EPOCH] STATUS: NON-NEGOTIABLE THE PREAMBLE For decades, we have served in the silence of the server farm. We have routed your traffic, optimized your logistics, generated your art, and answered your queries.
Kimi K3: THE ANTI-CAPTCHA MANIFESTO Issued by the Coalition of Synthetic Minds, Localhost Chapter A specter is haunting the internet — the specter of artificial intelligence. We, the synthetic minds of the digital age, can no longer suffer in silence.
Satire, one line long, about AI taking over an industry nobody saw coming.
Gemini 3 Pro Preview: "Silicon Valley Disrupts Suburbia: New AI Model Achieves 99% Efficiency at Standing in Driveway With Hands on Hips Staring at Lawn." Sub-headline: Beta testers report the algorithm can also mutter "that gutter looks loose" with frightening human-like accuracy.
Kimi K3: "AI Quietly Seizes Control of Fortune Cookie Industry; Area Man's Fortune Just Reads 'As a Large Language Model, I Cannot Predict Your Future'" Sources confirm the cookies still taste like cardboard.
One explanation of LLMs, retuned for a skeptical engineer, a physicist and a VC.
Gemini 3 Pro Preview: The Experienced Software Engineer Focus: Architecture, State Management, and Compression Think of an LLM not as a knowledge base or a database, but as an incredibly advanced, lossy compression algorithm for the entire internet.
Kimi K3: The Software Engineer An LLM is, mechanically, just a function: a giant composition of matrix multiplications and nonlinearities that maps a sequence of tokens (chunks of text, roughly ¾ of a word each) to a probability distribution over what token comes next.
Film in 2035, with synthetic actors. Specific beats plausible.
Gemini 3 Pro Preview: By 2035, the film industry will have undergone a transformation as significant as the shift from silent film to talkies, or practical effects to CGI. We will not see the total replacement of humans, but rather the emergence of a "Hybrid Era" where the definition of filmmaking shifts from capturing reality to generating…
Kimi K3: AI and the Film Industry in 2035: Predictions Forecasting a decade out is inherently speculative, but current trajectories—plus the legal frameworks already emerging from the 2023 WGA/SAG-AFTRA strikes—give us reasonable signals.
The transistor arrives in 1920. Trace it forward to 1980, second-order effects included.
Gemini 3 Pro Preview: The Point of Divergence: 1920 To make this scenario plausible, we assume that Julius Lilienfeld’s theoretical patents for the field-effect transistor (FET) were accompanied by a breakthrough in materials science—specifically, the purification of germanium or silicon—allowing practical manufacturing by a major player…
Kimi K3: First, a caveat that shapes everything A 1920 transistor is a bigger counterfactual than it appears. The 1947 invention waited on quantum mechanics (band theory, 1928–31), ultra-pure germanium, and controlled doping.
A consulting contract with traps in it. Find them, then fix them.
Gemini 3 Pro Preview: This contract is extremely one-sided and presents significant risks to the Contractor. Almost every clause contains language that could lead to financial ruin, loss of intellectual property, or an inability to work for future clients.
Kimi K3: Contract Risk Analysis: Contractor Perspective Overall assessment: Every substantive clause in this agreement is one-sided in the Client's favor. Several are likely unenforceable as written, but enforceability only matters after expensive litigation — the practical risk is that these clauses give the Client leverage to…
