> "Correctness" is subjective and unprovable.
Can you clarify how literally you mean that?
Because a statement like "1+1=3" objectively incorrect, given the usual conventions about what I would mean with that equation.

In my experience on SO with both SQL and Python, there are usually a number of correct answers for every question. How correct it is depends on things that usually aren't in the question: size of the data set, dependencies or processes that may break as a result of answer, etc.
It’s difficult to show a correct answer is good, or the best, for the question. Many answers you find on SO both provide a correct answer, as well as try to defend against and call out potential pitfalls and assumptions. Many answers also achieve at best “technically correct”, giving something that works, but slow, error-prone, inelegant, and really just a Bad Idea.
Technically correct is mostly a waste of time, unless nothing better exists. If this user is just technically correct (he’s probably not constantly wrong because he has more points than answers), then he’s ultimately not much better than your regular shitposter.
Binary is not a different math system. It's the same math system with the same rules but a different radix. 1+1 does not equal ten in binary. It still equals 2. You're just using a different notation for the same concept of two. The substance of the thing is not identical to how you signify it, which is why you can write "two", "2", "II", "2r10", ...all of which signify the same abstraction.
