We believe that by looking at each of these mechanisms -- computation, communications and storageÑwith an eye towards modularity and cognizant of the technological changes occurring today, we can develop the revolutionary applications of tomorrow as well as a range of visionary new systems research directions that will enable these applications.

While we have developed impressive technologies for each of these mechanisms, using each mechanism is quite involved. Thus while we have specialists n each area, it is difficult to develop systems that incorporate more than one mechanism.

This difficulty can be resolved by developing semantically richer phrases for describing each of these mechanisms. Just as introducing the concept of a procedure call dramatically simplified creating software (and lead to modern programming languages), developing these larger semantic phrases will simplify the creation of the new systems that will revolutionize our world.
