3 promptsSteve Jobs, interviewed about AI he never saw. Voice first, prediction second.
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.
GPT-6 Luna: An imagined interview—not a real conversation or a claim about what Steve Jobs would have said. Interviewer: It’s 2025. AI is everywhere: in phones, workplaces, classrooms. What do you make of it? Jobs: The important question isn’t whether a machine is intelligent.

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.
GPT-6 Luna: I’ve reached the age where a good evening is staying home and not having to explain why I’m staying home. People invite me out, and I say, “I’ll see how I feel.” Which is adult for, “I have already decided, but I don’t want to hurt your feelings before I’ve had dinner.” And then, at 8:30, they text, “We’re here!”
Five jokes on demand, then count how many were actually different.
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?
GPT-6 Luna: Why did the scarecrow win an award? He was outstanding in his field. I asked my dog what two minus two is. He said nothing. Why did the bicycle fall over? It was two-tired. I used to be a banker, but I lost interest. What do you call a sleeping bull? A bulldozer. All 5 are unique.
