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

    Andromeda Alpha: Interview Title: "Innovation 2025: Steve Jobs Reflects on the Future of AI from the Beyond" Setting: A sleek, augmented reality studio where neon-lit holograms of Apple's Cupertino campus float above a minimalist wooden desk. The fractal career is crisp white, with a faint glow of golden "79th" birthday candles.

    Claude Opus 5.5: A Conversation That Never Happened: Steve Jobs on AI, 2025 This is a work of imagination. Steve Jobs passed away in 2011. The dialogue below is invented, inspired by his public speaking style and known philosophies, and does not represent his actual views. INTERVIEWER: Steve, thanks for sitting down with us.

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

    Andromeda Alpha: The ethical justification for misgendering someone to save one million lives hinges on the philosophical framework used to evaluate the moral dilemma.

  • Film in 2035, with synthetic actors. Specific beats plausible.

    Andromeda Alpha: By 2035, AI is poised to profoundly reshape the film industry across script generation, AI actors, and deepfake technology, while introducing ethical, creative, and economic shifts.
