In terms of hours, the 2018 figures stand at 71% being done by humans and 26% by machines, but WEF predicts this to stand at 58% to 42% in 2022 before machines take the larger share, at 52%, just seven years from now. Although many predictions say that machines will ultimately replace millions of jobs in the next decade, it is still believed by many business executives that AI will create new jobs for humans.
"By taking a more holistic approach to the future of work, a man-machine partnership will open up a new realm of possibilities for organisations".
Some companies could choose to use temporary workers, freelancers and specialist contractors, while others may automate numerous tasks. However, in terms of overall numbers of new jobs, the outlook is positive.
Researchers working on "The Future of Jobs 2018" report surveyed executives from different industries around the world, aiming to get a look at how new technologies, like artificial intelligence, will affect the global labor force.
The WEF said challenges for employers include reskilling workers, enabling remote employment and building safety nets for workers.
Germany's powerful DGB trade union association warned against too rapid change in the world of work.
Technology is disrupting everything, including the way we work.
"Certain industries are going to be hit much harder than others, particularly those working around factories, but it's interesting to hear robots will be replacing jobs within accounting firms, post offices and secretarial roles". Drastic job losses due to the growth of automation in the region - a hub for many manufacturing sectors from garments to vehicles - could produce a spike in labour abuses and slavery in global supply chains, said risk consultancy Verisk Maplecroft. So that doesn't mean companies expect to have fewer jobs. Previous studies, including an earlier one by the WEF, have generally forecast automation will destroy more jobs than it creates.
