Five million jobs in the world’s leading economies could disappear over the next five years because of advances in technology.
   Developments in artificial intelligence, robotics, and biotechnology, would disturb the business world in a similar way to previous industrial revolutions, the World Economic Forum said in a report.
   Administrative and white collar office jobs are most at risk from a "fourth industrial revolution," the forum said on the eve of its annual meeting.
   It found that as many as 7.1 million jobs in the world’s richest countries could be lost. Those losses would be partially compensated by the creation of 2.1 million new opportunities in sectors such as tech, professional services and media.
   Countries will have to invest in transforming their workforce if they want to keep up with the changes and avoid a worse case of "talent shortages, mass unemployment and growing inequality," said Klaus Schwab, the founder and chairman of the World Economic Forum.
   Investing in education and adult learning programs is a good place to start
   Around 65% of children starting primary school today will end up working in jobs that don’t yet exist, and their future training is crucial, according to the report.
   Insisting on more diverse workforces in terms of gender, ethnicity and age, will also be vital for companies that want to succeed in the rapidly changing world.
