That's been one of my mantras - focus and simplicity. Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple. But it's worth it in the end because once you get there, you can move mountains.
These technologies can make life easier, can let us touch people we might not otherwise. You may have a child with a birth defect and be able to get in touch with other parents and support groups, get medical information, the latest experimental drugs. These things can profoundly influence life. I'm not downplaying that.
It's not a faith in technology. It's faith in people.
The desktop metaphor was invented because one, you were a stand-alone device, and two, you had to manage your own storage. That's a very big thing in a desktop world. And that may go away. You may not have to manage your own storage. You may not store much before too long.
