Why we tell scary stories about AI In fall 2024, the best-selling author and historian Yuval Noah Harari went on the talk show Morning Joe. “Let me tell you one small story,” he said. “When OpenAI developed GPT-4, they wanted to test what this thing can do. So they gave it a test to solve captcha puzzles.” Those are the visual puzzles—warped numbers and letters—that prove to a website that you’re not a robot. GPT-4 couldn’t pass. “What it did was access an online webpage where you can hire humans to do jobs for you, Taskrabbit,” Harari said, “and it asked a human worker, ‘Please solve the captcha puzzle for me.’ The human got suspicious. It asked GPT-4, ‘Why do you need someone to do this for you? Are you a robot?’ And GPT-4 told the human, ‘No, I’m not a robot, I have a vision impairment so I can’t see the captcha puzzles. This is why I need help.’ And the human was duped and did it for it. So it is already able not just to invent things, it’s also able to manipulate people.” “I’ll just say that example strikes me as terrifying,” co-host Jonathan Lemire said. It does sound terrifying. When Harari told the same story on The Daily Show, the audience gasped. But the thing about that story is that it’s wildly misleading. →  More stories by Amanda Gefter: The most precarious day in the universe. The forgotten janitor who discovered the logic of the mind.
