Some existing equipment cannot be controlled by computer, for example. Thus, the full exploitation of even the current generation of information and communication equipment may occur over quite a few years and only after a considerably updated stock of physical capital has been put in place. While such a scenario is quite plausible, we cannot be certain when, or if, it will occur.
Thus, we must be vigilant to ensure that our economy remains sufficiently flexible for entrepreneurial initiatives. And we must continue our efforts to further enhance productivity growth by raising national saving and spurring capital formation.
