There isn't a single unified software industry. 737 MAX problems happened in a software engineering and software development context embedded within one of the nominally most rigorously regulated industries that already exist.
MCAS failures was not a failure of software per se, but a clear system engineering and management failure, and a failure of all engineers involved, including ones that actually are licensed.
If nothing else, MCAS shows the limits of regulation, particularly in the failure mode of regulatory capture (FAA delegated too much power back to Boeing).
It shows the broken incentives of the lobbied failure mode. It does not say anything about the limits of regulation. In particular, regulation can say: you need to perform 100,000 failure-less flights across the globe without any passengers to approve the aircraft. I’m not saying it’s practical to do so, rather that regulation always has a headroom.
