They all tend to leave out one basic idea. Technology, be it a pencil or a 400MHz PC, is a tool created and used by man. Simply because a technology is available for use does not mean it controls the destiny of man, his communication, or of his future technology. Utopian views on the subject point to a rosy future, marked with easier communication, instant access to information, ease of life provided by computers, and less work for the users of such grand technologies. Depends on who you ask.
Technologies are simply tools that provide options for our use.
When we choose to use them we may be changing a sociological phenomenon, but that change is based on our choice to use the technology, and the creation of that technology by mankind. In Dave Anderson's paper on technological determinism we were introduced to the idea that to create new technology we must destroy old. This is a severely flawed argument. Yes, certainly, because the tools we use would no longer be available to us. But, that does not mean that we couldn't revert to formerly popular tools.
