Part 4: As people rely more and more on technology to solve problems... Certainly, the use of technology may get us into some unexpected troubles, and even prevents us to think properly. It needs to be stressed, however, that the reliance on the technology is not among the many subjects of our worry, for technology is only a part of our man-made environment. We rely on them just like we rely on the fruits on the trees billions of years ago, and the problems it causes are similar to mammoths and saber tigers our ancestors have encounters, which may have deteriorate their ability to solve problems by frightening and distracting them every now and then. Interestingly, humans thinking ability is so vulnerable that it can be easily “deteriorated” by so many elements, and we can only discern these elements from certain bad consequences caused by, accidentally or inevitably, misuse of some technology. But reliance on technology as a whole? To deny it is either to deny the whole history of human being of developing and using technology, or to admit humans will be better off if they live in a completely “natural” environment, ignorant and indifferent to any technology, throwing away everything that might make their lives safer and more convenient and ,very likely, surrounding themselves still with scary wild animals.
