Thanks. You are right, the comparison is off probably on both sides.

As with critical civil/structural engineering projects, there are software development projects built with correctness in mind. I've worked on a few of those, mostly in aerospace and VLSI simulation in the late 70s til the early 90s, and the level of engineering was very high.

Fast forward two decades to the world of web development and corporate IT and, wow, the lack of rigour is simply abysmal. I can imagine the same been true in the housing/building sector.
