Great changes made by science and technology With the development of science and technology,we are in an era of information now.Of couse our life have great changes made by science and technology ,it become more and more convient today.But,the development of science and technology also gradually make us in danger. With the rise of the internet and smartphones,lots of people become ‘the phone freak’.If some people lost their phone,they will look as lost their life.this is the disadvantage. What’s more,some scienstists want to research the artificial intelligence ,gene clone technology and aline today.however,it will make human beings get into touble.As Stephen Hawking said that the development of full artificial intelligence could spell the end of the human race. In my opinion,people should take advantage of the science and technology.Don’t make human beings destroyed by the science and technology.
