Just as a reader with no particular dog in the philosophical (or semantic) fight over how well we do or don't understand the brain: That rude remark lowered rather than increased my estimation of your knowledge or authority on any subject you would be discussing. Generally, people who are highly knowledgeable and confident on a subject don't resort to telling others they are out of their depth, because they don't need to. At the very least, it's suspicious to throw an ad hominem into your rebuttal.

Winning a debate is about convincing the audience, and I found that an unconvincing statement, apart from it being an obnoxious rhetorical tactic.

But it did make me think of The Big Lebowski. "You're out of your depth, Donnie!"
