In examiming the agent literature, Tom has found two essential new concerns. One, a qualitative difference with software engineering concerns in the past, namely, agents combine a large number of underlying technologies, and are hence very complex artifacts. The second is a real difference in relation to past software engineering concerns, i.e., the use of introspection in the implementation of an agent. The use of anthropomorphisms in agent technology may be dangerous because it might lead to an illusion of understanding of concepts which does not actually exist. For example, I have never found a proper definition of the concept of autonomy, at least one that can be used for the design and analysis of agents. So, for me the most interesting rsearch challenge in relation to agent technology is the management of the complexiity of multiple technologies referred to above. The use of coordination technologies might be an aid to deal with this complexity.
