This reminds me of a chilling short story I read a while back, but I cannot remember its name. It was about a machine learning algorithm trained on social network archives to take as input a body of dialogue between people and communities and to output statements which would strongly divide them. As a joke, the developers ran the algorithm on their internal corporate email and read the output sentences, laughing that anybody at their company could possibly come down on the other side of any of the resulting statements before realizing that they were talking about different sides. No longer being able to stand each other, the company dissolves. It was a good story if anyone recalls its name.
