I think you're putting the analogy in the wrong place. In this context, civil engineering isn't a "domain" any more than software engineering. Both are exercised in support of the "actual" domains relevant to business or society.

The more analogous question is: as a civil engineer, could you tell which structure was designed with the help of a civil engineer, and which was designed by a domain expert (e.g. a transportation administrator) with automated civil engineering?
