I think that if that were the case, the change would be brutal. First, because as a comment below suggests, fewer people would be involved, so coordination would be simplified. Second, because many more people could access these coordination positions, and I think it would be likely that other professions would take on those roles, professions or personality types that are not usually "good coders" but now wouldn't need to be, since the machine itself could explain, for example, the general functioning of what is being produced. Therefore, I would expect the job field to be radically affected and salaries severely reduced.
