Seriously, among other things Rosen's work "comforts us" that Cyberdyne's intelligent yet malignant robots can be safely consigned to the realm of science fiction, and need not be entertained as a possibility capable of realization in any real human future.
Unless they find a way (are programmed by their designers) to be originators and willing agents of "formal causes." I don't know how it is even possible for such a thing to be accomplished — but the AI folks around here might have some ideas about that. And if they do, I hope they will weigh in with their insights here, soon.
I further acknowledge this subject matter deals with an entirely open question at this point. But a potentially immensely fruitful one. And I can tell you that there are scientists who appreciate Rosen's insights, and are now following his lead....
For instance, see an article by Kineman, J.J. and Kineman, J.R., "Life and Space-Time Cosmology." It was presented at the Proceedings of the 44thAnnual Meeting of the International Society for the Systems Science. Toronto, Canada. ISSS, in 2000. Unfortunately, it does not seem to be available at their site. (Why it is so difficult to locate on-line is beyond me.) But a friend who attended passed along a copy of the presentation, in Word format. If you'd like to see it, give me a yell via private FReepmail.
