Same with aviation and safety. I honestly believe all programmers should, early in their careers, do a brief "tour of duty" in an industry where the stakes are high and "good enough" isn't good enough. You might not choose to make it your entire career, but at least you're exposed to the discipline, however briefly. Most software developers today have never in their lives worked on a project where defects were taken seriously and where there was process and documentation designed to reduce their occurrence.
