That distinct feeling when reading AI is as if someone who wrote it was compelled to write more words
Because that's literally what it is. Its an algorithm that is continuously asking itself, 'what is the most likely word I should say next?'
Whereas an author that is intending to communicate a point, will start with an idea, write a passage to explain the idea, and then edit their passage to the minimum number of words that most precisely, accurately, and succinctly communicates that idea.
