AI "content" is trivial to make and will soon be everywhere.

It's been everywhere for many years already.

Plenty of content mills have been using "templates" and stupid AI models to churn out articles for like a decade, there are whole YouTube channels made of videos that are just an AI generated script read by an AI with random barely related visuals in the background.

The only difference is that simple templates were easy to spot, so search engines like Google would penalize them down to the 10th page of results, while modern AI output is at a level undistinguishable from stuff written by a human.
