People

    People may live for up to 120 years and use new technology to help when people go blind, deaf

and have other problems. The number of people over a hundred years old could go from 135,000

today to 2.2 million people by 2050. By 2015 people think that 100 million workers will be able to

work from home for a company in a different country by using the Internet.

Money

    Worldwide e-business will become even more successful with online shops that sell special products

for each person, which will be brought to their house the next day.

Environment

wind and Sun energy could become much cheaper and many more countries could use it. This would

be very useful in poor countries. The air in big cities would also become much cleaner and healthier as

a result.

smaller and lighter. Very, very small machines could take away rubbish, make things in factories, and
