You're right of course, these nuances COULD be deeply analyzed and determined and then objectified. My only contention is that it may be too difficult to identify and then create the logic to be coded. I won't say impossible but it would be incredibly tough.
Quote from cornix:
Agree on nuances, but if think of it, most nuances are still objective. Yes there are many, but each makes logical sense and is not just some "feeling".
So probably it's a complex formula, too complex for automation currently, but doesn't mean it's not objective.
