In the past, technology and progress was very slow. People “invented” farming 12,000

years ago but it took 8,000 years for the idea to go around the world. Then, about 3,500

years ago, people called “potters” used round wheels to turn and make plates. But it took

hundreds of years before some clever person thought, if we join two wheels together and

make them bigger, we can use them to move things.

In the last few centuries, things have begun to move faster. Take a 20th-century invention

like the aeroplane, for example. The first acroplane flight on 17 December 1903 only lasted

12 seconds, and the plane only went 37 metres. It can't have been very exciting to watch, but

that flight changed the world. Sixteen years later, the first plane flew across the Atlantic, and

only fifty years after that, men walked on the moon. Technology is now changing our world

faster and faster. So what will the future bring?

One of the first changes will be the materials we use. Scientists have just invented an

amazing new material called graphene, and soon we will use it to do lots of things. With

graphene batteries in your mobile, it will take a few seconds to charge your phone or

download a thousand gigabytes of information! Today, we make most products in factories,

but in the future, scientists will invent living materials. Then we won't make things like cars

and furniture in factories - we will grow them!

Thirty years ago, people couldn't have imagined social media like Twitter and Facebook.

Now we can't llve without them. But this is only the start. Right now, scientists are putting

microchips in some disabled people's brains, to help them see, hear and communicate better.

In the future, we may all use these technologies. We won't need smartphones to use social

media or search the internet because the internet will be in our heads!

More people will go into space in the future, too. Space tourism has already begun, and a

hundred years from now, there may be many hotels in space. One day, we may get most of

our energy from space too. In 1941, the writer Isaac Asimov wrote about a solar power

station in space. People laughed at his idea then, but we should have listened to him. Today,

many people are trying to develop a space solar power station. After all, the sun always

shines above the clouds!
