> that software engineers should be held responsible for something that (as far as we can tell so far) was an accident and not the result of negligence or malice
Nobody said that. The original comment said developers should be held "accountable for a crime that if committed directly by a person would almost certainly result in jail time" [1].
The standards from medical devices and/or civil engineering, with the associated licensing requirements and verification processes, make sense. Even in the case of a careless mistake or strategic oversight, individuals who could have known but nevertheless signed off should be identified, if not explicitly punished.
