No, it doesn't. The "I'm an expert at AI detection" crowd likes to cite things like "It's not X, it's Y" and other expression patterns without stopping to think that perhaps LLMs regurgitate those patterns because they are frequently used in written speech.

I assign a <5% probability that GP comment was AI written. It's easy to tell, because AI writing has no soul.

I think at this point it's not easy to accurately detect whether or not something is AI written. A real person can definitely write like this. In fact, that's probably where the LLMs got their writing style from.
