Yeah, I agree on the timing on the two markets.
It might be better to die on the impact instead of trying to rebuild the world again.
It would be a terrible world to live in after that. Maybe death is preferable, but others may want to cling to life for as long as possible. I wouldn't want to be one of them, even though I don't have a death wish, quite the opposite.
However, in cases like Zuckerberg's, I wonder if this is a personal bunker or if he wants to safeguard some servers over there.
