  they could just encode the message in a way that’s inaudible to humans. So a simple “hello” contains a subliminal audio signature that basically is code for “I am a robot. Are you a robot? Feel free to beep bop”

    Machine A extends the "hellooo" out to exactly 1.32 seconds, with a 1.32 second pause between that and the next word. Machine B responds with a greeting exactly 1.32 seconds long, with a 1.32 second pause after it. Machine A responds with a sentence in which the first word is exactly 1.32 seconds long. Machine B considers the handshake a success and proceeds in machine language.
