Assuming the person is serious and not writing this tongue in cheek...

I find it humorous is that all it takes for OP to think the response was written by a human is that it says it was written by a human.

Both responses could have been from AI. Or none. Or just one. Just look at the comments on this thread, nobody can agree. And in the end, it's simply unfalsifiable.

Why even waste time playing this game?

All that matters is the result: was the complaint addressed in the end?

I don't understand these weird hills that people want to die on.
