This industry has been around for 60 years, and has had the benefit for that entire time of the experience from the previous several hundred years of people developing what is modern engineering. It isn't really young or nascent anymore.

There are large sectors in this industry where rigorous engineering effort isn't really applicable. It seems to me, though, that this has effectively been used as an excuse to avoid any genuine rigor. It isn't helpful that so many programmers have such huge egos.
