The World Future is a group of people from more than 100 countries who are interested in how modern technology(技术) is making our life better.
They think the things that we will be able to do in the future should help us live better in many ways, at home and at work, in our own country and around the world. Here are just two of them:
●People live for up to 120 years and use new technology to help when people go blind(盲), deaf(聋) 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 lnternet.
●The new technology of “nanotechnology”, that is very small robots or machines, will make all the things smaller and lighter. Very, very small machines could take away rubbish, make things in factories, and help people take away fat in our bodies. By 2020 people will probably be able to wear these small machines that look like watches. They will give us lots of information about our bodies and help keep us healthy.
