AI learned this figure of speech from humans. Even the frequency in which it is used is copied from humans. So you can't really use it to determine if something is written by an AI or not.
Can you point to examples of these patterns with the same frequency in any written content dated any time prior to 2024?
But I have no issue with your argumentation whatsoever, it is just that I think there is more than sufficient evidence, and you think there is not.
