As you say, most of the stuff in the bookstores is pulp.
Almost everything at the grocery check out stand is pulp.

And the articles and sordid escapades we read in such are so generic, so cookie cutter, that an AI can be trained to write them.

"Men bad, women empowered" write that in 100s of ways, but all saying the same thing with the same buzzwords and the same tone, and you have Vogue magazine.

poor people talk about people (stars, hollywood)
more intelligent people talk about politics.
really intelligent people talk about things and solutions.

People® Magazine could be easily written by an AI, because it just the same thing over and over, just change the name of the actress.

Politics has also been reduced to memes and sound bites.
And i am pretty sure that AI is writing these.

But, when an AI gets into the stuff i want to talk about, it become real obvious.
Worse than a 5yo joining an adult conversation.
The AI doesn't have enough information to write anything, and there are too many side passages where you can tell an AI just copied from a bunch of different things, put it into a blender and press pureé.
Nothing there to sink your teeth into.

Where AI is used, that i really, really hate is responding to tweets and such.
Like a one track minded person, it just gives canned responses.
And this makes the average reader thinking that there are more of this type of person. I see more "A" than "B" so i'm inclining to go with "A". (because of our group mentality)

And these AI responses really make me sick.
You can tell they are AI by various means. Like, there really isn't a person there. Nothing personable. They are also very quick to respond. Sometimes its an actual troll, but usually there's some fun there.
