From self-driving cars to carebots (care +robots) for elderly people, rapid development in technology has long represented a possible threat (威胁) 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 (AI) 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 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.

    You fall down on the road and a kid you barely know rushes over to help. You come home after a long day to find your dad has prepared your favorite meal. Just before lunch in social studies class, you learn about places where people don't have clean water or enough food.They're likely to make you feel grateful.

    Gratitude (感恩) is one of many positive emotions. It's about focusing on what's good in our lives and being thankful for the things we have. It's taking a moment to reflect on how fortunate we are when something good happens — whether it's a small thing or a big thing.

    Making a habit of gratitude can also be good for us. Like other positive emotions, feeling grateful on a regular basis can have a big effect on our lives. Brain research shows that positive emotions are good for our bodies, minds, and brains.

    Positive emotions open us up to see more possibilities and take in more information. They improve our ability to develop skills, learn, and make good decisions. When we feel grateful for someone's kindness toward us, we may be more likely to do a kindness in return. Thanking people can make it more likely they'll do a kindness again.

     When we feel and express heartfelt gratitude and appreciation to people in our lives, it creates loving bonds, builds trust, and helps you feel closer.
