Fortune reports on chatbots used in online stores to talk potential customers out of abandoning their virtual shopping carts. “…A startup called UpSellit is … using live chat to act as a sales assistant …. but here’s UpSellit’s twist: That person on the other end of the live chat box isn’t a person at all. You’re chatting with software that’s designed to fool you into thinking it’s a person.” Clearly another step blurring the real and virtual that raises a few ethical and possibly legal questions. How would knowing that you’re talking to a bot change your attitude or behavior? What if you thought you were talking to a bot but it turned out be a real human being?
