The volume of machine-generated spam — microtargeted clickbait, specifically — on the internet could grow by an order of magnitude or more, making authentic human text a minority. That will hasten the demise of the internet as a democratic medium, because intelligent people will be increasingly reluctant to wager their time and attention on unvetted prose of uncertain provenance. This has been the trend for some year…
I think you are more or less right, unfortunately. Neal Stephenson's sci-fi book Fall, or Dodge In Hell, contemplated this possibility and suggested we would develop an entirely new layer to the internet based entirely on verified human identities to kind of re-create the internet.
