Don't let the fact that Power Shift was published twenty years ago, in 1990, make you think it's not relevant. Toffler's writing in 1990 is a spot on prediction for the world we are living in and the world still to come.
Take the monetary system. Where before we measured the value of money by figures printed on paper now we measure the value of money by symbols printed on a computer screen or information stored on smartcards. Where before money use to represent a specific amount of gold, today money represents only the fact that who ever takes it from you believes it's got value. It’s a matter of faith.
Plastic money is another leap of faith. You never actually see your money except when printed on a computer screen. This has its advantages since you don't have to crawl around the floor looking for coins after turning your pants upside down for the zillionth time without checking the pockets first.
What's strange is that even if plastic money seems to be the cheaper option compared to paper money, banks have figured out ways to make it look as if it's the most expensive option ever considered when you gawk at your bank charges. This is my opinion not Toffler's.
When money changes banks change. What do banks keep if they do not keep paper money in vaults but only blimps on computers? Could other companies do that just as well as banks? What power will banks have if they loose the power they have over the current monetary system? Toffler makes the point that our entire perception of what power involves and means is changing.
Work has changed and will change fundamentally. Work use to be measured by the time you labored, in future work will be measured by how hard you think and how easily you can transform information and knowledge into more useful information and knowledge. Where you could in the past teach someone a job in an hour or less new jobs require skills and it takes a long time to train employees. Therefore companies will want to hang on to those employees who they've spent some time to train.
When work changes power structures change. Governments who don't realize that knowledge is the basis of current and future development will be left behind.
Individuals and corporations who harness the power of technology in providing quality information, knowledge and services will be the ones who thrive and will have the power to influence the world.
