Wittgenstein would have such a field day with the semantic games we're playing these days. The disclaimer basically says: "man" has a purely subjective meaning, but we're going to keep using the word anyway because we know you know what we mean objectively. Kind of funny if you think about it. I think that's what the (̶n̶o̶w̶ ̶n̶u̶k̶e̶d̶) comment was pointing out.
