They take you 15 seconds to say that to come up with that. No, I've thought about before. Okay. Good line. It's making fun again. There's a difference. Oh, that's good. All right. She's inventing. I'm not all intimidated. And there's a causal history to that fun. You mentioned that there's no way to communicate with aliens until there's overlap in the causal graph. Communication includes being able to see them. Is communication any kind of detection? And if so
