"Sure! I have defined a privilege constellation specifically for engineer types who can come here anytime they want to access the house as a museum of dead tech. That’s what I mean by the flex space analogy. To me and my guests, it’s a home. To these visitors . . . there’s one right there." Chester waves his arm across the room (it is a central room maybe fifty meters on a side) at an engineer type who has set up a Hasselblad on a huge tripod and is pointing it straight up at a bent landing gear strut ". . . to them it’s exactly like a museum in that there are places they can go and other places that if they step over the line will set off alarms and get them in trouble."
