A true story: a well-known futurist writer was invited to speak at a tech conference attended by some of the world's richest techies. They took him in a back room with five other billionaire types and started asking him questions. He thought this was prep for the real talk he had prepared, and he was telling them what he knew about crypto and things like that. But what they had brought him for was his advice on surviving the apocalypse. Like 'How can I continue to control my staff and guards if money is no longer worth anything?'

The writer told them, "I don't really know about that, but you might start by treating them well now." They thought he was joking. They talked instead about how to lock up the food in ways that only they would know how to unlock.
