Siemen's Tobias Unger shows us the important deffierences in implementing chat bots as compared to humans: "Humans adapt, so humans are able to use the knowledge they have to deal with unexpected situations. Sally would never do that, because, you have to train each and every capability yourself. Of course, there will be enhanced algorithms or mechanisms in the future, maybe, to ensure that there is a part of self-learning, but you have to be very careful with that, because you want Sally to behave perfectly."
