A while back a study was performed where the researchers wanted to see how a young chimpanzee would adapt to living life with humans if it was treated just like a human child. And so it was adopted by a family with a human child for its sibling. What ended up happening was the human child adapted to behaving like a chimp to a way larger degree then the chimp behaving like a human.... Humans capacity for imitation is very strong, and so no one should be surprised that our behavior with chatbots will mold the minds and speech patterns and behaviors of the human users.
