But there is more content than there are people who can watch it. What do you think happens when the production curve grows way past the consumption curve?
Google will be forced to delete unviewed content more frequently, or start charging for hosting video. The latter of which would probably help reduce the amount of garbage content on YouTube.
A lot of garbage content on youtube is exactly because of google’s offered incentive to get users to produce more content. I wouldn’t be upset if clickbait garbage gets archived away.
