I obviously can't speak for you, but there's not a freaking chance I'd trust my life to the servers I run.

To go maybe too literal: when I'm working on machines that could physically eat me, I don't trust myself with just one off switch -- I want redundancy. And since computers are horrible piles of ridiculous complexity, the closest I can get (and not really get close) is trusting some of the top minds to overthink the crap out of it in a way that I can't do with the systems I manage.

But again, YMMV.
