I mean yeah, we are not living in sci-fi yet, but AI today can convincingly recreate voices of people and rearrange words in sentences etc. So indeed it kinda is a glorified chatbot, but I think the more complex chatbots become, the less distinguishable from the real thing they become. Just that I don't think it is possible to recreate a feel of a person from hours, even long hours, of conversations to record them, even if they took all their reddit/facebook/twitter/youtube posts and comments, it still would not be enough
