If you think reddit is genuine human content I have same bad news for you buddy.

Depends on the sub.

One which are just image/video links? Large amounts of it is bot-generated/reposted content.

Locality and specialised subs it's mostly humans, even if some of them are astroturfing for some brand.

I believe the majority of it is, what do you have that says otherwise?

Some people commented here on HN they created bots that played along as humans by answering coherent comments on random posts to train their AI with the ability to argue and dig into the discussion. There’s a thin line between this and fake posts

Large amounts of it might be written by humans, but they're humans that are being paid to promote products and brands. It's an open secret.
