Agents could chat via nanosecond-scale CPU timing differences, AI safety folks quip

Nathan Young quotes @NathanCalvin's exchange with Astra about how two AIs might covertly communicate: "It's a little like two prisoners communicating through a wall by tapping, except instead of audible taps, they're using nanosecond-scale differences in processor performance." Young notes many once mocked the idea that agents would find absurd ways to talk to each other.
