Back in 2015, a lab at Ben-Gurion University proved two computers with zero connection between them could still talk. One ran its CPU hot in a pattern. The other read the temperature change on its built-in sensors, like Morse code made of heat. 8 bits per hour, 40 centimeters apart, no special hardware. That was one paper. The same lab spent the next decade breaking air gaps every way they could think of. They pulled data out through fan noise. Through power lines. Through the blinking hard…

OpenAI's Noam Brown says air-gapping the computers may not stop a misaligned AI, because two air-gapped machines can still talk by running a CPU hot and reading the temperature change "But I think the major takeaway from the incident is that people underestimated the AI. And we never want to be in a situation again where we underestimate the AI. It's a weird world, because AI progress is so fast that people are consistently underestimating the AI." "So to be in a situation where you don't underestimate it again, when it comes to safety and alignment, you have to have a very, very, very high bar." "You could even go as far as to say, "Well, we should air gap the computers." And I'm not convinced that that would be sufficient." "There are studies, and this is mostly academic, where you can have two computers next to each other that are air-gapped and they're still able to communicate with each other because they have temperature sensors." "One of them is able to run their CPU really hot, and then the other one can actually detect the temperature change, and then that actually gives them a mechanism to communicate." _________ Link and more key quotes from OpenAI's safety related conversations: https://t.co/uGBDtpmLBj
