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 purer and simpler age. But as history shows, the past was not that wonderful. It was not so bad for a privileged minority, 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 and short.
우리가 좋던 말던 간에 우리가 사는 세상은 지난 100년간 매우 많은 변화를 겪었으며, 앞으로의 100년에는 더 많은 변화를 할 것이다. 어떤 사람들은 이 변화를 중단하고, 좀 더 순수하고 단순했던 시절이라고 생각하는 그 때로 돌아가고 싶어한다. 그러나 역사가 보여주듯이, 과거는 그다지 멋지지 않았다. 소수의 특권층들은 현대의 약(의학품) 없이 살아야 했으며, 아이를 낳는 일은 여자에게 매우 위험한 일이었으나 그다지 나쁘지 않았지만 대다수의 인구는 삶이 고달팠고, 짧았다.
Anyway, 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 government money for research were cut off, the force of competition would still bring about advances in technology. Moreover, one cannot stop inquiring minds from thinking about basic science, whether or not they were paid for it
