Can you tell if a comment is AI?

But such sort < 10 word comments as those shown are likely mere copies or mere rewordings of actual human comments. So not much to work with. For a trivial example consider the comment "wow, that's great!". Was it made by an AI or a human? Does it even matter? The informational content is so low, it might as well be an old school markov output.

Make it slightly larger and one call tell way more easily.
