If Dropbox accidentally destroyed just one person’s file, he said, it could erode the trust of all its users. “This is like the same sort of genre of problem as the code that you use to fly an airplane. Even if it’s a little bug, it’s a big problem.”

As someone who writes code for jet engines, I find this perspective laughable. A better analogy would be if an automated baggage handling system lost your bag. You'd lose your stuff and the airline would lose your trust. You might rant about it on a blog and a few people would get upset and switch airlines with you. But nobody dies.
