Is There a Need for AI to Drive Content Creation Costs to Zero?

My fear is that by driving content creation costs to zero, it will spur the creation of vast new oceans of terrible content. The idea that there would be the creation of more information from my brain to handle is sort of intimidating. To me, it sounds mostly like a shift in the division of labor between machines and humans. If for some reason human humor is just really hard to replicate then your task is just a different task.
