whether we like it or not ,the world we live in has changed a great deal in the last hundred years ,and it is likely to change even more in the next hundred .Some people would like to stop these changes and go back to what they see as a pure and simpler age .but as history shows ,the past was not that wonderful .It was not so bad for a privileged monority ,though even they had to do without modern medicine ,and childbirth was highly risky for women .but for the vast majority of the population ,life was nasty ,brutish ,and short .
Any way ,even if one wanted to , one couldn't put the clock back to an earlier age .
knowledge and techniques can't just be forgotten .nor can one prevent further advances in the future .even if all goverment is doing its best ,the force of competition would still bring about advance in technology .moreover ,one cannot stop inquiring minds from thinking about basic science ,whether or not they are paid for it.the only way to prevent further developments would be a global state that suppressed anything new ,and human initiative and inventiveness are such that even this wouldn't succeed .All it would do is slow down the rate of change .
