Just watched an interview on CNN with the Governor of Hawaii and their director of emergency management. Pretty impressed that the director didn't throw anybody under the bus. He basically said "An employee pushed the wrong button. It's my responsibility, so this is my fault. We're going to make procedure and technical changes to make sure this doesn't happen again."
No way we should accept errors like this as some sort of blameless par for course in software engineering. Especially as SV grows more and more into life-critical systems like autonomous vehicles. If there was deep incompetence in architecting a system like this then yes, potentially the employees responsible for that architecture could be disciplined. If the responsible employees were too junior to design appropriate safeguards correctly, then the finger points at the managers who set up the team that way.
It sounds like the parties to blame here lie somewhere in the management chain between the poor unfortunate button-pusher and the director of all emergency management for Hawaii.
