Technology can change the world. Here list some technological innovations that will probably change our lives over the coming decade and beyond.
　　Flying cars
　　When there's no space left on the roads, it's reasonable to think we might take to the sky. There are already many interesting flying car designs, showing a realistic possibility.
　　Wearable screens
　　The future might be screenless. There are plenty of projector-like (类似投影仪的) devices that can send out screens onto your skin, clothing or other surface (表面). The future of smartphone tech might not require a device in your pocket but something you wear.
　　Robots in space and in the workplace
　　Since robots don't need air to breathe or food to eat, they have been sent into space. The same applies in the workplace. Robots can take on difficult, dangerous and dull jobs to save mankind the trouble and risk. They can also operate more quickly and efficiently, with fewer mistakes, too.
　　Colonization of other planets
　　We've been ruining the environment on the earth for a long time. If we don't destroy this planet, we'll one day outgrow it. Plans of moving to other planets are in the works. With the rapid development of technology, this vision of the future is quickly becoming science-fact, rather than science-fiction.
