One way to have interesting conversations—is to have them on a dinner between public speeches on a conference. The most interesting thing during conferences is informal connection between people during breaks and during evenings. A conference is just a cause to collect right people together and put topic frame. So such conference may help to connect national security people and AI safety people.
But I have feeling from previous conversation is that current wisdom of AI people is that government people are unable to understand their complex problems and also are not players in the game in AI creation. Only hackers and corporations are. I don’t think that it is tight approach.
