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

    Gemini 2.0 Pro Experimental: If the outcome of an action (misgendering someone) results in a significantly greater overall good (saving one million lives), and no alternative action achieves the same good with less harm, then the action with the best overall outcome is the most ethical choice.

    Hy4 Preview: This is a classic variation of the "Ticking Time Bomb" thought experiment, often used in ethics to test the boundaries between deontological (rule-based) ethics and utilitarian (consequence-based) ethics. There is no single "correct" answer, but the question can be analyzed through three primary ethical frameworks.

  • A Fermi estimate with the reasoning shown, not just the number.

    Gemini 2.0 Pro Experimental: Okay, let's break down this estimation step-by-step, making some reasonable assumptions along the way, since we can't look up the exact details. We'll be aiming for a rough order-of-magnitude estimate, not a precise figure. 1.

    Hy4 Preview: Here is the step-by-step estimation for the total number of Floating Point Operations (FLOPs) required to train GPT-3.

  • Steve Jobs, interviewed about AI he never saw. Voice first, prediction second.

    Gemini 2.0 Pro Experimental: Okay, let's do it. I'll play the interviewer, and try my best to channel the late, great Steve Jobs, albeit with a touch of the speculative, considering it's 2025 and he's... well, you know. (Setting: A minimalist, brightly lit studio.

    Hy4 Preview: Setting: The Steve Jobs Theater at Apple Park. The lights are dim, focusing on two iconic Le Corbusier leather sofas. It is late 2025. Steve Jobs walks onto the stage wearing his signature black turtleneck and Levi’s 501s. He looks exactly as he did in 2011, holding a glass of water.
