From self-driving cars to carebots (care+robots) for elderly people, rapid development in technology has long represented a possible threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence continues to change businesses.

    “The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia Pacific.

    A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.

    The report is based on interviews with 200 experts, business leaders and young people from Asia Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates.

    But the report states: “Losing occupations does not necessarily mean losing jobs — just changing what people do.” Growth in new jobs could occur as much, according to the research.

    “The growth of 20 to 40 person companies that have the speed and technological know-how will directly challenge big companies,” it states.

    A 2014 report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create,” according to Aaron Smith, the report's co-author.

    “Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft's Jonathan Grudin told researchers.

    My first visit to Angkor Wat was in 1980. The country had been at war for many years and the temple was deserted and falling to pieces. Plants were growing out of the roofs, and trees were growing in the courtyards.

    Today, the temple is the scene of a busy repair programme. A team of 15 Indian experts are organizing a workforce of 400 Cambodians, most of them women, who are cleaning, repairing and rebuilding parts of this temple.

    As I walked through the courtyards, I noticed the Cambodian women devote hours to cleaning carefully a tiny area of stone. Boards are laid down to protect the precious painted stones while the repair work is going on. There are very few machines and little heavy equipment. Workers carry building materials in buckets at the end of long poles. Piles of stones lie in a corner of the courtyard, waiting to be replaced.

    The work of cleaning the stones is watched over by three Indian chemists. It is a very slow task. First they clean the stones with brushes using buckets of a weak chemical. Then gaps between the stones are filled in. Finally another material is painted onto the stones which will protect them from water forever.

Work starts every day at 7 a. m. and goes on until late afternoon six days a week, with a break at midday.

    Evening is the best time to visit the temple, after the tour groups have left. As the sun sinks lower, shadows spread across the courtyard. After sunset, the sky turns pink. The grey stone towers take on a golden colour before turning pink. Nowhere else in the world can there be such a quiet, beautiful place.

    My grandfather grew up in war-torn Europe. When German soldiers occupied his hometown, the thriving city of Tarow, Poland, he refused to obey them and eventually joined the Soviet army to fight for his country's freedom. “Stand straight, stand tall,” he told himself.

    After the war, in 1947, he boarded a boat for Manhattan. He was hungry and suffering from seasickness. All alone in a new country, he was frightened about his future. Still, he marched head-on into the hustle of the streets of New York. Soon he met other European immigrants, each of them trying to find his or her own way. If they could do it, why couldn't he? “Stand straight, stand tall,” he would remind himself.

    Thanks to the help of a loyal and trusting friend, my grandfather gained a jewelry booth on Canal Street, New York City. He once told me how nervous he was on that first day of work. He was not only trying to learn this tough new business, but also a new language.

    To his surprise, the men in neighboring booths－who could have taken advantage of him－offered their help and advice. Within months, my grandfather was commanding his spot behind the counter, selling diamonds and cultured pearls as if he'd been doing it his whole life.

    Stand straight and stand tall.

    In later years, my grandfather would take both my mother and her sister down the aisle at their weddings. As he stood with each of them, he thought about their new beginnings, and of the adventures and journeys they would experience together. He also thought about the children who would one day carry on his family name.

    I am so proud to be one of those children. Listening to my grandfather's remarkable experiences has changed the way I view my own life.

    One February afternoon, Jesus Delgado was on break behind T2 Tacos, where he works as a cook, when he heard a commotion(骚动). He ran to the front of the Los Angeles Taco stand and saw a man and a woman arguing. She was screaming for help and had two young boys at her side. All of a sudden, the man hit her in the mouth, seized the smaller boy, and ran down the street.

    "I followed my judgement and chased him." Jesus, 35, told the Argonaut newspaper. The older boy ran in the other direction to get help. A group of teenagers who had witnessed the attack assisted the woman, Lauren Kornacki, and called 911. She told them that she was the boys' babysitter.

    Within a few blocks, Jesus caught up to the man, Andron Gazarov, 33. They fought, and Jesus wrestled (抢夺) the young boy from Gazarov's arms. Then Gazarov threw himself onto the sidewalk. "He was yelling at me that the kid didn't belong to me. I was telling him the kid didn't belong to him," Jesus told the Argonaut.

    Minutes later, Los Angeles police officers arrived and arrested Gazarov, who was charged with kidnapping, attempted kidnapping, and attack. He faces up to 12 years in prison, if convicted (定罪). The kids, Brendan O'Brien, 6, and Grady O' Brien, 4, were unharmed.

    The next night, the boys' father, Tom O'Brien, went to the Taco stand to thank Jesus for his actions. He also started an online fund to help Jesus pay the medical expenses for his special-needs daughter. By May, more than $27,000 had been raised.

    Hadi Partovi, founder of Code.org believes every student should learn the basics of computer science just like they do math, physics, or biology, regardless of what they want to do in the future. The expert says knowledge about the subject is important to understand how the world around us works and compares it to learning about photosynthesis(光合作用), even though not every student is going to be a botanist. To spark students' interest, he created the “Hour of Code,” which introduces the world of computing to anyone, from ages 14 to 104, in a fun, interactive manner. Observed annually during Computer Science Week, the event now draws tens of millions of kids from over 180 countries.

    The “Hour of Code”, which can be scheduled anytime during Computer Science Week, begins with an introductory video on computer science. Participants can then select from hundreds of fun assignments that are sorted by both grade level and coding experience. Though each project is designed to last just sixty minutes, beginners can deal with as many challenges as they desire.

    To help introduce computer science in classrooms on a more regular basis, Code.org has also developed a catalog of online courses that can be incorporated(纳入)in a school's regular curriculum. Since the nonprofit began offering the courses in 2013, over 704, 000 teachers have signed up to teach introductory computer science to over 22 million students worldwide.

    Thanks to the efforts of the pioneer, about 40 percent of US schools now offer computer science as a subject. The numbers are even higher—an impressive 70 percent—if after-school offerings such as robotics clubs are included. Even more encouraging, eight years ago, just 19, 390 students took an Advanced Placement Computer Science exam. By the spring of 2017, the number had jumped 415 percent to 99, 868.

It is amazing how many of the things in science fiction and movies have become reality.For instance,in the movie Star Trek,the workers could go to a replicator(复制器) and order food,drinks or anything they could program into the computer.Before long,the item would appear.This is possible today,in a way,with technology we have had for years.

Several manufacturers(制造商) have created 3D printers.One company,MakerBot,has created a printer that the average person can afford.It is called The Replicator.You can download a lot of design software from the Internet for use with The Replicator.In the near future,rather than going to a store to buy what you need,you may be able to download what you want from the Internet and print it out at home.

The process was first used with music.At the very beginning,music was recorded onto plastic disks with etching(蚀刻法).Music can now be copied without a physical product.____ Rather than having to buy a physical book or magazine,you can now download them from the Internet in digital form.

This technology is already used in engineering and architecture.Melissa Shoes,a Brazilian foot wear company,is using this technology to create shoes.Rather than having to go through the current process of product design and development,the company is able to design and print shoes for display to see how well they will sell before having lots of them made.
