The uncontrolled/unchecked monetary incentive is starting to cause things to get out of controll.
I recently spotted a channel that features what seems to be animal traps (for mice, snakes, fish etc). All of their videos have hundreds of thousands of views, and all are 100% fake. It's hard to know if you're not outdoortsy, but they're all fake.
Essentially they're not just producing garbage content, they're also intentionally damaging the perception and world model of the people watching their videos.
Why is this "allowed" to run? Why aren't the knowledgable people calling them out? Because Youtube completely destroyed the comment feedback system.
Negative comments and critisism is burried, new comments and unpopular/harsh comment are deranked, so all you get is dumb catchy comments that increase view time.
Of course this is only the top of the iceburg in a sea of garbage content, but it shows where we're heading, and it'll only get worse with the proliferation of machine learning tools, especially lifelike text-to-speech technologies.
