Computing is currently just a tool, although a very advanced one at that. On the whole, computing just is a more advanced knife or hammer, enabling us to do our jobs better, whether that be running an office or discovering scientific advances. Computing has not totally achieved what other scientific advances have done for mankind, such as farming has for lifestyle and educational development, and social structure.
However this tool is developing branches in other areas such as communication - we now have a whole new method of communication through the internet, so social change may happen more decisively in future if the internet is developed with social communication in mind.
Cybernetics will provide, in the more distant future, a larger degree of social change, as will computing's effect on the business of managing our evolution and quality of life (cloning, stem-cell research, genetic engineering and genetic determination).
So far we have only developed machines that can process large numbers, but much larger numbers involved in much more complicated calculations than our own brains can handle. However our simian grey matter still has the edge in pattern recognition, speech recognition, imagination and creativity, linguistics, moral and ethical reasoning and emotion.
