I don't quite agree with the speaker's assumption. Even as the technology develped so much, we can't deny that people's mind changed a lot, but difference doesn't means 'dereriorate' as the speaker metioned. Changes might be in the positive way, or even made people have stronger ability to think for themselves.     If we ask a question that which section of technology changes most rapidly nowadays. I think no body would diagree that developing of internet is one of the most rapid domain.  Smartphone using especially, and smartphone is the relied the most for people these days. But do the people with smartphone thinking ability deteriorated? I can't agree so. More smartphone using bring more Apps, most of the Apps sending the information to the user.  To be a searcher, it's like swim in the ocean of information, and searching for the tiny starfish. How can we find it in a shrot time. The only solution is to improve our selfthinking ability. It is easyer to get the infomation (by google it for example) but more doesn't means accurate, there might be some fault. To intriguing the correct one, we need more alility with critical thinking. Such examples that new technology brings new thinking ability are not just in mordern life but insist with all the humanbeing history.    After the camera first invented, some of the art critist stated that the painting is dying, and deveopment of art   would be traped. But at the same time, impressionism was seeded. The artist didn't just paint what the saw, they also want to express what the felt. Not olny the light or color, but also the mood and insight. The ability of art thinking deveoped by the triggle of technology. And at the same time, photograph is developing in to a standalong form of visual art. Even more art is not olny in the field of paint or photo. With the technology rely, we have movies, experience art， activate art， interaction art and so on. Could we define this kind of change is "deteriorate"? I think it is just the opposite we have stronger secant of art that allow so many kinds of art being appriciated.   The techology like the tool of thinking, it helps us to think more efficient. or it offers us a new way to solve the problem. some of new tech make it easier to solve the problem which is hard before.  It save time and tailent for  humanbeing to do more explore. I won't deny some of the individual might using this kind saved time to do some useless thing. But it is not because of the technology. it's the unwillingness. so I have to say that the techonlogy brings us new thinking path, offering us the new efficient thinking tool, our mind and thinking ability is and will be changed alot. maybe more efficient, maybe more rapid, but not surely deteriorate.
