Thomas Christaller Fraunhofer Institute for Intelligent Analysis and Information Systems Sankt Augustin, Germany. What does Artificial Intelligence tell us about Natural Intelligence? Artificial Intelligence started from a very naive understanding how to make computer systems as intelligent as people are. But the more powerful computers and especially software were built the more open questions of the whole endeavor were posed forward. What are the basics of intelligence? Is a body a necessity? When a technical system seems to be intelligent how intelligent is it really? And finally: What is intelligence and why does it exist? Where does intelligence pay-off either in humans or in technical systems? The thread of argumentation will be that there must have been profound reasons why intelligence came into being during the evolution of homo sapiens. One way is to simulate models from natural, cognitive, and brain sciences for a better understanding of human intelligence. But it is a completely different story to construct artificial systems which are intelligent. While they shouldn't aim to mimick or emulate every aspect of a human, we have to select the principles underlying human intelligence and we have to make them work in the technical realm. The talk closes with a discussion of possible consequences in constructing truly artificial intelligent systems.
