It would be foolish to worry about an apocalypse when you're not sure it's going to happen. Instead, worry about why your users have to click three times instead of two.
I guess there are always apocalypses (apocalypti ?) hanging around. Killer bees, asteroids, sudden catastrophic climate change, killer cosmic rays from a supernova, some freak of physics, accidental nuclear war (or deliberate), some big volcano and so on...
Of course the real danger for a personal apocalyse: getting in your car and driving. We live with it every day. No big deal.
