1¡¢    As for old people, some of the applications are hard to use because they didn't grow up with them. They don't have simple models of how they should work, what to do when something doesn't work or where to go for help. We make it as easy as possible to be used for people who are not familiar with the technology.

    I think there is huge potential and we are designing it. The ability to connect to friends, who remember the same movies, news and music, is really important, especially as people get old. They end up in retirement at home and they aren't always close to their friends. Allowing the network to help them connect with friends and family is a really powerful thing.

    My mother is an enthusiastic user of the Internet, although it took me years to get her to use e-mail. She was born with normal hearing, but lost it when she was 3. She was totally deaf for many years, until age 53, when she got ear aids. They work really well. That is a big change for her. But before then, her friends couldn't call her on the phone, so they suggested she use e-mail to communicate with them.

    Young people don't even think of the Internet as technology. It's just there, and they use it. There's been a very interesting change in communication styles between old people and young people. There are some kids who are now in their teens and aren't willing to make phone calls. And they think e-mail is old-fashioned and slow.

    The reason why teens don't make phone calls seems to be that they don't know what to say. When they call, they often stop for a while and there's a silence. On the other hand, texting is considered proper, and it's okay if you don't answer. You might have been distracted. It's not rude. But it is strange if you're in this kind of conversation and simply stop talking.
