I mean, in the example you're responding to, many of the people aren't doing the "technically correct" answer of, "microbial life will continue".

They're just morons who heard, "life finds a way" and assume humans will be fine.

No, it’s not the “best kind of correct”, it’s being an asshole.

That's the joke, though.

The character being quoted, from Futurama, is usually insufferable and often miserable.

Edit: Interestingly, the character is also relatively well liked and generally appreciated by the rest of the Planet Express crew. It's a pretty nuanced quote, in context. It kind of says "You're not wrong, and your correction is arguably unnecessary and objectively objectionable, but we love you, anyway."

It's like talking about powers and saying "The square of 4 is 16" and they'll bleat "Actually, a square is a shape" and you're trying to find a way to tell them that their contribution is absolutely worthless and irrelevant to the topic.
