As a developer, I worry about this. However, I also don't work on systems that could cause anyone a level of harm resulting in criminal damage. If I did, I'd like to think I'd increase the care I put into my craft 1000x. I realize that's not doable in many companies, and that's the problem. Too many companies taking the "move fast and break things" attitude towards people's lives and safety. This is how you invite the big foot of government regulation.
