The “One question” riddle
If you can ask only one question to figure out how many AI agents are in the room(if any), what that question would be in order to be viable for longest possible time in the years to come?
P.S. 1. The human agents are willing to cooperate you and will try to answer your question, so if no answer is received you may consider that agent for AI. 2. The AI agents have internet access and can use every online resource available.
