The internet will become entirely AI bots talking to each other with no humans writing or reading.

That is the future of AI. Everyone will use it whether they like it or not because there won't be an alternative.

Just look at global warming, caused by our totally negligent behaviour.... AI will decimate people's thought processes and they essentially become zombie like. And it will take a few decades until they realize what have they done. It will be a painful experience to shoo off people from the heroin called AI in order for them to use their brains again.
