I wouldn't describe software as most people experience it as more complex.

And civil engineering projects are constantly fixing unforeseen design problems either during construction or afterwards.

I would distinguish the failure modes as different though eg analog vs digital. Real world engineering can absorb an awful lot of minor mistakes through safety factors etc. Failure can be gradual or just a matter of degree or even just interpretation of standards. Software failures are often more digital or only matter when "under attack"
