Computers are faster than humans, but humans are better in many tasks. This is not only due to the fact that we are "smart". In many cases of everyday life we are not using our cognitive power, since we have no time, or we simply are so trained to the task that we do it "without thinking". Instead of using "reasoning", we often reply on heuristic methods, that are fast, frugal and "ecologic", but in some situation fail spectacularly. Autonomous agents and portable devices are becoming pervasive, they have to interact more and more with humans. Moreover, it might be possible to exploit the knowledge that evolution has stored in human heuristics in the ICT field.
