Yes, but they are good at what they do. Software is more conplex and has a culture of fix it in production that would make it far more risky to sign.

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"
