While it's true that the value of content is driven down by the signal to noise ratio, AI being noise, the fact that AI can't be copyrighted is an important distinction. Only humans can copyright, a court-tested fact.
Does that fact increase the quality of content? No. What it does mean is that humans can monetize their works and eat; AI can make content and sell you ads or influence you to buy something.
This reduces to a question: Do you want to feed humans or the AI muck? The choice is yours. Some humans probably don't deserve the feeding; the AIs are driving up all of your costs, from the power grid energy bills to the new AI trappings being foisted on you during your tech experience. You decide.
