I think you're being misunderstood because it is often hard to tell with individual comments. I don't think you'd disagree: it wouldn't be hard to program a bot to say "How do I delete someone else's comment?" and all the other junk memes you have to skim past in the top comments of every popular post.

But I think I get what you're saying: on an aggregate level, there's a sort of dynamic, organic culture here that I don't think bots could reproduce. They can copy memes, but they don't make new ones. They don't decide to have spontaneous earnest conversations in the middle of joke threads, or write 6-page dissertations in response to a question in a 2-day-old 15-deep comment with 2 upvotes.

And I think if you tried to reproduce that behaviour with bots, the result would be...pretty obviously weird, and not in a charming Reddit way.
