The Internet will turn into the world's greatest marketplace because it will be such an easy way to find out information about products, including who has the lowest prices. Quite a bit of shopping we do in person today will be done over the Internet in the future, and whenever we buy a physical object, it will have to be delivered. Much of our shopping will be done from electronic catalogues, which can be more convenient than paper ones. An online catalogue can know your tastes and emphasize items you are likely to want.

Over the next ten or twenty years computers are going to get very good at recognizing the spoken or written word, and the little video cameras that we're using for teleconferencing also will allow computers to recognize gestures. The computer will know if you nod or shake your head, and it may even read your lips to improve the accuracy of its voice recognition. The keyboard will remain important, but it's going to lose the importance it now shares with the mouse as an input device.

"Telephone" refers to an audio-only electronic communication link, and we'll continue to have this kind of connection. But I think audio-only communication will be the exception rather than the rule. In the office communications will usually involve video conferencing, collaborative work on a document or some other kind of data interchange beyond audio alone.

In the future people will be healthier than they are today, but it will depend on a few things. We will have the information that we need to be healthier. We know more now than we've known before about the role of diet and physical activity in health. We have more vaccines than we've ever had before, so we're going to be in a position to prevent more illnesses. Of course, there will be new infections, but I think the modern opportunities to improve our health will be greater than the challenge we'll face.

At least 60 percent of people in this country are not engaged in moderate physical activity, and another 25 percent are completely sedentary. I think that through a combination of education, motivation, and incentives we'll see progress in this area. At the work site there's an increasing number of ways businesses can provide opportunities for employees to exercise at work, and they will find it a way to decrease the cost of healthcare for employees. So there will be incentives for employees to become more active because it benefits the company financially.

The ability of people to travel from one place to another, to be in one city today and somewhere else in the world tomorrow is going to improve and increase. There will be more tourism. So we're going to have more mega-cities where problems are incubated, not just infectious diseases, but violence, because the gap between the haves and the have-nots will widen. All these things worry me in terms of our ability to prevent and control them.

I think we're already seeing some dramatic changes and I think this will continue and accelerate. First of all, we are seeing the tremendous increase in the number of television channels. This will mean that the audience will become even more fragmented. Then, there's the fact that these channels are becoming more global through satellites. Next comes the dramatic rise in the universal comprehension of the English language. Finally, there is the change in the content of programming, particularly in sports.
