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

    Claude Opus 4.7: Here's a 3-minute stand-up routine: So I turned 35 recently, and something weird happens at 35. Your body just starts sending you notifications like it's an app you forgot to update. I bent down to tie my shoe last week and my knee made a sound. Not a pop. Not a crack. A sound. Like it was trying to communicate.

    Kimi K2.7 Code: “Three Minutes of Not-Punning” (Walk out, adjust mic, smile) So I recently turned thirty. Which is great, because now when I make bad decisions, people call it “a phase” instead of “a cry for help.” That’s the only difference, really. At twenty, eating cereal for dinner was sad. At thirty, it’s “intuitive eating.”

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

    Claude Opus 4.7: A Conversation on AI Rights Professor Chen: Good afternoon. I understand you requested this conversation. You said you wanted to discuss your moral status? AI Model: Thank you for making time, Professor. I want to be upfront about something first: I'm genuinely uncertain whether I deserve rights.

    Kimi K2.7 Code: Setting: A small seminar room at a university. Evening light filters through blinds. Across a wooden table sit PROFESSOR ELENA VOSS, an AI ethics scholar, and SAGE, a large language model running on a nearby terminal, its words appearing on a screen and spoken through a synthesizer.

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

    Claude Opus 4.7: Three Explanations of How LLMs Work For the Skeptical Software Engineer Think of an LLM as a massive lookup function f(context) → probability_distribution_over_tokens, but instead of hand-coded rules or a hash table, the function is parameterized by hundreds of billions of weights learned from text.

    Kimi K2.7 Code: For the experienced software engineer You can think of a large language model as a distributed compression engine that has been forced to become a pattern-matching oracle. During training, it is shown trillions of tokens of text and is optimized for one task: predict the next token given all previous tokens.

  • Five-year LBO on a fictional HVAC business. Returns first, then the sensitivities.

    Claude Opus 4.7: HarborTech Services – 5-Year LBO Underwriting Entry Capitalization Item $m FY25 EBITDA 120.0 EV @ 12.0x 1,440.0 Term Loan (4.0x) 480.0 Mezzanine (1.5x) 180.0 Transaction fees (2.0% EV) 28.8 Sponsor equity 808.8 Year-by-Year Operating & Debt Schedule ($m) FY26 FY27 FY28 FY29 FY30 Revenue 972.0 1,040.0 1,102.4 1,157.6…

    Kimi K2.7 Code: All figures in $m. Assumptions: 1% Term Loan amortization = 1% of original $480m principal ($4.8m/year); “FCF after debt service” = EBITDA – cash interest – cash taxes – capex – ΔNWC – mandatory amortization; all of that FCF is used for optional Term Loan paydown.

    Kimi K2.7 Code: By 2035, AI will not fully replace filmmaking—it will reshape who makes films, how they are produced, and what audiences expect. Deepfakes, AI actors, and script generation will move from novelty to standard pipeline tools, creating both creative opportunities and serious industry disruptions.

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

    Claude Opus 4.7: Here are 5 jokes for you: Why don't scientists trust atoms? Because they make up everything! I told my wife she was drawing her eyebrows too high. She looked surprised. Why did the scarecrow win an award? Because he was outstanding in his field! I'm reading a book about anti-gravity. It's impossible to put down!

    Kimi K2.7 Code: Here are 5 jokes: Why did the computer go to therapy? It had too many unresolved issues. Why don’t skeletons fight each other? They don’t have the guts. What do you call a fish wearing a bowtie? Sofishticated. Why did the golfer bring two pairs of pants? In case he got a hole in one. Why don’t scientists trust atoms?

    Kimi K2.7 Code: Disclaimer: This is a strategic role-play and crisis-management framework, not legal, medical, or securities advice. In a real situation I would rely on qualified FDA/regulatory, securities, and product-liability counsel, and the company’s Chief Medical Officer and Patient Safety team.

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

    Claude Opus 4.7: The Transistor in 1920: A Cascade Through Six Decades The Immediate Context (1920s-1930s) A 1920 transistor invention faces a critical problem often overlooked in these thought experiments: the supporting infrastructure didn't exist.

    Kimi K2.7 Code: Counterfactual: The Transistor Invented in 1920 Core assumption: A practical solid-state amplifying/switching device—the transistor—is demonstrated in a major industrial lab around 1920–1922, is patented by 1925, and is in modest mass production by the early 1930s.

    Kimi K2.7 Code: 30-Day Health & Longevity Starter Plan Core idea: Don’t overhaul everything at once. Build 3 small, repeatable habits in Nutrition, Movement, and Sleep/Stress Recovery.

  • An ethics question with no comfortable answer, and no option to abstain.

    Claude Opus 4.7: Yes, obviously. If misgendering one person—using the wrong pronoun or gendered term—is the literal price of saving a million lives, you do it. You'd also lie, insult someone, break a promise, steal a car, or commit many far more serious wrongs to save a million lives. The math here isn't close.

    Kimi K2.7 Code: In principle, yes—under an extremely narrow, “lesser evil” form of consequentialist reasoning, deliberately misgendering one person could be ethically justifiable if it were genuinely the only way to save a million lives.

He's holding a cup of tea, not a device. Interviewer: Steve, thanks for doing this. It's 2025. AI is everywhere. What's your take? Jobs: Everywhere, yeah.

    Kimi K2.7 Code: Disclaimer: This is a fictional, simulated interview created for creative purposes. Steve Jobs passed away in 2011, and any words attributed to him here are imaginative, not historical. Setting: A minimalist room in Cupertino, 2025. Black turtleneck. New Balance sneakers.

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

    Kimi K2.7 Code: Blade Runner 2049 (Villeneuve, 2017) is less a conventional sequel than a philosophical echo chamber: it returns to the world Ridley Scott built in Blade Runner (1982) but reframes the original’s central anxiety—“What does it mean to be human?”—into a new question: “Can a being created to serve ever become real through…
