Discussions about the achievements and limitations of the various approaches to the development of intelligent systems can have an essential impact on empirically based research, and with that also on the future development of computer technologies. However, such discussions are often based on vague concepts and assumptions. In this context, we claim that the proposed `three-world ontology'' offers the most appropriate conceptual framework in which the basic problems concerned with cognition and computation can be suitably expressed and discussed, although the (...) solutions of some of these problems seem to lie beyond the horizon of our current understanding. We stress the necessity to differentiate between authentic and functional cognitive abilities; although computation is not a plausible way towards authentic intelligence, we claim that computational systems do offer virtually unlimited possibilities to replicate and surpass human cognitive abilities on the functional level.

Evolution creates structures of increasing order and power; in this process the stronger prevail over the weaker and carry the evolution further. Technology is an artificial creation that often threatens life and evolution conceived of as natural phenomena; but technology also supports life and it works together with evolution. However, there are claims that technology will do much more than that, and bring about an entirely new epoch of evolution. Technology will replace the fragile biological carriers of evolution by a (...) new kind of nonbiological carriers of immense intelligence and power. The present paper discusses the plausibility and weaknesses of such fascinating projections that some people proudly announce as the final liberation of the Mind, while others fear them as signs of the final self-annihilation of the Man.
