Mark Zuckerberg has worked his ass off for like 20 years to go live in an underground bunker. Granted, it's a large and luxurious underground bunker, but this does not seem like an improvement.
Mark Zuckerberg controls the largest mass-persuasion device on earth - literally controls, he's got more than 50% of the shareholder votes - and is using the proceeds from owning the globe-spanning apocalypse machine that he's turned Facebook into to build himself a bunker underground to survive the apocalypse his machine is creating.
Just turn off the goddamn machine and you can actually enjoy Hawaii, Mark. All the good stuff is above ground!
