Science has proved to be the enemy of man" How far is this true

On the face of it, the statement seems to be utter nonsense. Today, if we have a toothache, we can visit a dentist who can perform a painless extraction or make a permanent filling. A hundred years ago, dentistry was carried out by a barber with a pair of pliers. Medicine, through science, has made astonishing strides in improving the lot of mankind.
Future is also linked with science as there is no future without science.
Science . Well Science holds the key to our future.It is the most powerful tool that we have .Everything our society is today is due to scientific advancement. Without it, we'd still be sitting in guttering candlelight in drafty houses ravaged by disease with an average life expectancy of 45.Science has made our lives comfortable -less diseases, more medicines ,less manual work ,more useful results and many more.
Communication , transportation, health , entertainment ---we don't see a Future without science in any of these fields.So the days are not far when humans will become completely dependent on machine , and for those days we need to improve our knowledge of science so as to make our future bigger abd better than before
