Earth has been hit by objects in the past, with devastating effects. Scientists largely agree that it was an asteroid or comet impact that started the chain of events that wiped out the dinosaurs around 60 million years ago.
[...] impacts from objects in space are just one of several ways that humanity and most of life on Earth could suddenly disappear.
We are already observing that extinctions are happening now at an unprecedented rate. In 2014 it was estimated that the extinction rate is now 1,000 times greater than before humans were on the Earth. The estimated number of extinctions ranges from 200 to 2,000 species per year.
From all of this very worrying data, it would not be a stretch to say that we are currently within a doomsday scenario. Of course, the “day” is longer than 24 hours but may be instead in the order of a century or two.
So what can we do about this potential prospect of impending doom?
[...] But the threats we face are so unpredictable that we need to have a backup plan. We need to plan for the time after our doomsday and think about how a post-apocalyptic Earth may recover and humanity will flourish again.
As computer experts, you are familiar with backup plans. What should we do to backup human survival ?

If shit happens they are also more likely to be snuffed out. And then there's the radiation issue. LEO is not really "true space" and outside of it is hard to protect. So underground on a planet makes sense.
Easy come but hard to protect.
The cost just shows up somewhere else. No easy soil or ice to play around with for starters.
This is probably something needed.
Bring them to the moon. Less shit that happens if it crashes and it will still be near enough.
Yes, that is definitely something worthwhile to look into. Though so far no really profitable business scenario have shown up. The real break is a off-Earth industrial base re-supplied solely using space resources.
