I think this is related to how badly things go wrong if there is a fuckup. You really do not want to push the engineers responsible for determining your $500M office building will stay standing.
So what kind of fuckup in software is going to have to happen before this is also true? My fear is that it will happen one day, if not already (see eg- 737 MAX). I'm not looking forward to that day.
The 737 Max was not a software fuckup. The concerns raised by the engineers were overruled by management, and then buried during certification.
