Abstract

Improvements in computational hardware enabled by nanotechnology promise a dual revolution in coming decades: machines which are both more intelligent and more numerous than human beings. This possibility raises substantial concern over the moral nature of such intelligent machines. An analysis of the prospects involves at least two key philosophical issues. The first, intentionality in formal systems, turns on whether a “mere machine” can be a mind whose thoughts have true meaning and understanding. Second, what is the moral nature of a machine vis-a-vis a human: can a machine be a true moral agent, capable of real responsibility, possessed of rights and duties? If so, might a machine be a better moral agent than a human?
