I think you put it in a much darker light than necessary. Many of these problems can be solved by making hardware for which it is impossible for software to cause these problems. Finally that's what we did in the era when not everything was software controlled: design the stuff in a way that it doesn't explode in your hand. Of course, for electonical stuff this would require firmware which can't and doesn't need to replaced. Therefore it'd need to be tested rigorously and the manufacturer can't control devices out there retroactively.
