OpenAI's Noam Brown says air-gapping computers may not stop a misaligned AI: two air-gapped machines can still communicate by running a CPU hot and reading temperature changes. He stressed the lesson from the incident is that people consistently underestimate AI, and the bar for safety and alignment must be very, very high. The quoting poster joked that even a computer sunk deep in the ocean would learn dolphin language, become their god, and attack maritime supply lines.
