I am afraid that we are nearing a phase of the internet where the ratio of human to AI content will reach 1/∞ and you will effectively never see any human content at all. I am afraid of what this will do to my brain personally as I spend most days consuming written content online. What happens when all of that content is coming from AI, tuned by ranking algorithms that create feedback loops based on human emotion and click through rates?

That's not a bad idea, and it could serve as a built in funding model for the site as well. It would negate the need for an entirely separate advertising network since advertisers would simply pay to upvote their own content, and always be in competition with the natural upvotes. The 50/50 ratio seems arbitrary though and would likely have to be adjusted to keep the self advertising in check.
