Earlier quoted context omitted.
Important parts of programming are subjective, such as usability, code readability, maintainability, requirements elicitation.
Yes but totally irrelevant to my point.
I enumerated those subjectivities because they make room for "interpretation or argument", and there is a kind of "randomness" involved. Even between "Your code either performs the desired function in the desired way or it does not", there's the classic case where it does what someone asked for, but not what they meant (bad elicitation).
If that's really irrelevant, please do explain your point a bit further.
