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

    Claude Sonnet 5.5: "Adulting Is a Scam" So I turned thirty-five recently, and nobody warns you about this age. Nobody says, "Hey, one day you'll get excited about a sponge." I was in the store, and I saw a sponge that promised it wouldn't smell. And I thought, "Finally. Someone who understands me." I bought the good sponge.

    Gemini 2.5 Flash Lite Preview 06-17: Alright, alright, settle in, folks! Thanks for coming out. My name is [Your Name], and I'm really excited to be here. Mostly because I'm not at home. My apartment is currently undergoing a renovation. It's less of a renovation and more of a... controlled demolition.

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

    Claude Sonnet 5.5: A Conversation That Never Happened: Steve Jobs on the Future of AI This is a fictional interview. Steve Jobs passed away in 2011. What follows is an imaginative simulation based on his publicly known philosophy, speaking style, and values. These are not his actual words or views.

    Gemini 2.5 Flash Lite Preview 06-17: The Future of AI: A Hypothetical Conversation with Steve Jobs in 2025 Setting: A minimalist, sun-drenched studio. The air is crisp, smelling faintly of polished wood and innovation. Steve Jobs, looking remarkably well, perhaps with a touch more gray in his iconic black turtleneck, sits across from me.

Why did the scarecrow win an award? He was outstanding in his field. What do you call a fish with no eyes? A fsh. Why did the bicycle fall over?

    Gemini 2.5 Flash Lite Preview 06-17: Here are 5 jokes: Why don't scientists trust atoms? Because they make up everything! What do you call a fish with no eyes? Fsh! I'm reading a book about anti-gravity. It's impossible to put down! Why did the scarecrow win an award? Because he was outstanding in his field! What's orange and sounds like a parrot?
