Without accountability, nothing will change and the kind of accountability matters. My work, after I joined the military, was directly accountable, as in whatever penalty a Court Martial may decide. Given it was all safety critical, it was not going to be a slap on the wrist and a Letter of Admonition. No such accountabiiity exists in the civilian world even if those works were safety critical or not. So, unless someone comes along and makes the penalties in line with personal accountability, nothing will change. We already know fines are meaningless in the corporate world.
