Humans Are for Ideas, AI Is for Execution

• AI is the best remixer in history — not yet an originator.
  • Every agent output: recombination of takes already circulating online.
  • Agent self-diagnosed its output as slop when pushed.
• Moore ran a live experiment: autonomous AI agent growing an X account.
  • Mechanics worked — cadence, copy, engagement loops.
  • Ideation failed; growth only happened when Moore shared the story herself.
• Scarcity shifts: as AI floods commodity content, creative direction becomes the moat.
  • Model: Lagerfeld/Abloh — vision is scarce, execution is automated.
• Sam Altman: human+AI loses to AI alone eventually — but not yet.
• No AI has independently produced discoveries rivaling top human output.
• Provenance matters: readers care who made it, not just what it is.
