Other thing I found amusing is the idea that humans are already fully stationary. OK I know obesity, netflix, etc. but then again how can one imagine life without walking, without going somewhere?
Even disregarding utter lack of space to move about, I would actually find such an existence boring. We spent at times beyond 70 days on passages. Not to say the passages were boring, but you know a
boat moves on there is the illusion of progress.
The guy and his wife absolutely look like the kind of people you want to party with though ! ;-)
