3 . Forging a 5G future

The future in sci-fi movies seems so close, yet so far away. Delightfully, 5G technology makes that future look easily achievable. Schools, hospitals, transportation, factories—even our homes will soon use this powerful wireless network. Last year, China started testing 5G mobile networks in its several cities. So what is 5G? It's the latest generation of cellular (蜂窝状的) network technology.     1    

5G's benefits mainly come from speed and connectivity (连接).    2    People will be able to use the Internet at a much greater speed than before. Imagine being able to download an entire movie in just a few seconds! That's how fast 5G will be.

    3     For example, one of the biggest problems with developing driverless cars is the delay between sending a signal and receiving it. Driverless cars must be able to react instantly to sudden changes in their environment, such as a dog running across the road. This will require these cars to send and receive huge amounts of data within milliseconds (毫秒).    4     It will also allow doctors to perform operations remotely, using robots. The robots will respond more quickly to the doctors’ movements.

So what about 5G's connectivity?       5    . Imagine having a smart home that automatically turns the lights on when you open your front door.

"New things become possible when you can move information at a massive scale," Gordon Smith, CEO of telecom equipment reseller Sagent, told The Telegraph. "5G becomes the great enabler. "

No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.

4 . People have always wanted to know what the future will look like. Then, how can we?     1       The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago, such as food, sleep, the feeling of being appreciated and loved.     2     No. In addition, generally speaking, the inventions for the last 150 years have been a human effort for freedom and communication, to be able to get in control of the time and world. Since there is still much to do in this area, this will be the focus at least for the next 150 years.

But why do we need to predict the future? Predicting the future is important for two reasons: First, we need to start to think about what kind of future we would like for ourselves and to pass on to the next generation.     3    

How about the virtual worlds? It might be in the future to experience the sand between your toes, and hear the waves, just lying in your bed at home.     4     So, even if a great invention is there for an affordable price, it’ll never take the place of the common experience if it is not real.

    5     What we’ll see in the next 50 years is the transition (过渡) from an oil-dependent society to a new society. Here there’ll be new medicine, continued exploration of space, challenges in the climate change, and new inventions that make life a little easier.
