Whoever claims that he never saw his software deployed to production with bugs has never written anything of any complexity. Adding "... he knew about" to that

Whoever claims that he never saw his software deployed to production with bugs has never written anything of any complexity. Adding "... he knew about" to that statement softens it a little, but not too much. Problem comparing software engineers to the civil engineers lays in the ability of the latter to constrain their users, e. g. stating the weight limit for the bridge. Try to do that with software and enforce it.
