The value of material wealth is giving way to the value of information. In this time of transition, these apparently incongruous value systems mix and form hybrid systems for determining value. Information that is useful but scarce is also valuable. Scarcity, even in an era marked by an abundance of information, is still a key factor in determining value. Those who hold valuable information may still wish to maintain exclusive, proprietary control - to increase the life of the information.
Information is subject to decay or aging.
Information is not inexhaustible. It may revert to data, the raw material from which it is formed. Contemporary art is part of an emerging sector of the economy called information and knowledge. Knowledge-workers create information for others to use. Worker in this case does not imply those who act only upon the instructions of others, knowledge-workers think for themselves.
