Real quotes from Reddit comments that inspired this opportunity

  • “LLM thinks 10,000 days is enough to casue genetic evolution. Wow. I mean the prompt was offbeat but even a basic sense of science tells you this is asbolute bs”
  • “proof you shouldn’t rely on AI to ‘predict’ nonexistent catastrophic futures”
  • “This is just ridiculous, even from a scientific point of view. For one, it would not reduce the supply of drinkable water since rain is distilled water”
  • “when AI became a thing I kept asking them what would this 'insane scenario' would look like but it still was just speculation.”
