19．Though the next 5 billion people who connect to the Internet will experience a better quality of life and improve society，technological advances can also"empower some terrorists"，Eric Schmidt，leader of Google，said on Tuesday．
Co-author of the recently published The New Digital Age，Schmidt explored the promise and the hidden trouble of a completely connected world．"The terrorists can get phones，too，"he said．"But terrorists will make mistakes，and it'll be possible to track them down"
He cited the Boston Marathon bombing investigation，which got quick results by broadcasting and sharing photos of the suspects．In another case，police also said the victim left his cell phone on，which allowed them to track the suspect's vehicle and arrest the suspect at last．
Jared Cohen，founder of Google Ideas and Schmidt's co-author，said，"It's going to be difficult for criminals and terrorists to operate off the Internet．When individuals that do criminal activity are using technology，the room for error goes up．"
"The biggest thing that Google and other companies can offer is the mobile device you carry，which you'll become even more dependent upon，"Schmidt predicted．"It can remember things …and make suggestions that surprise you．"
"Privacy and security are the ultimate shared responsibility between companies，government，and the people who are actually using the tools，"Cohen，The New Digital Age co-author，said．"More connectivity doesn't remove the importance of human judgment in the future．"
He predicted that parents are going to have to educate their children about online privacy and security perhaps years before having"the talk"about the sex education．
"It'll be a long time before the machines take over the world，"Schmidt said．"The main problem in society is not that the machines are taking over the world，but rather，automated machines are taking over some low-skilled jobs．"
"The answer to that，of course，is education，"he added．
