What will the world of the future be like? There are plenty of people who are happy to give their opinion of what we will be doing in 2050.Here are two predictions about the world of tomorrow.
When we dream about the future, many like to think of owning a personal flying car.The advantages are obvious.This technology would allow total freedom of movement.We could fly at 480km per hour, avoiding traffic lights and busy roads.However, some people believe there will be problems with traffic control.If the cars become popular, there is likely to be an air traffic jam.Another big problem is mechanical failure( 机械故障 ).What will happen if the cars stop working? These are problems we must expect if flying cars become a reality.
Three-dimensional(3D) printing is another new technology with exciting possibilities.3D printers are used to build an object with liquid plastic.They build the object layer by layer until it is complete.Car companies already use 3D printers to make life-size models of car parts, and medical companies use the technology to make man-made body parts.As we move into the future, 3D printing will revolutionize( 彻底改变 ) the way we shop, the way we manufacture products and the way we treat sick people.The disadvantage is that such equipment will be extremely expensive.
So, in the future, we might be able to fly to work or print out new shoes.Although there are some problems to solve before this will be possible, we can certainly dream of a world where technology makes life easier and safer for millions of people.
