I mean, that's just a really weird scenario. Even ignoring the implausibility of modern offices being a thing in 300 years from now, much less being controlled by the same company, what exactly would've motivated Neumann's great-great-granddaughter to walk into an office space in which she'd apparently be an unknown stranger to critique the behavior of someone in it?
To be clear, I'm not asking for someone to make this sound reasonable -- just, what sort of scenario, reasonable or otherwise, might Neumann have been imagining here?
