Overall, we estimate that about half of the activities that people are paid almost $15 trillion to do in the global economy have the potential to be automated by adapting currently demonstrated technology…

All occupations will be affected. Only a small proportion of all occupations, about 5%, consist of 100% of activities that are fully automatable using currently demonstrated technologies. However, we find that about 30% of the activities in 60% of all occupations could be automated. This means that many workers will work alongside rapidly evolving machines, which will require worker skills also [to] evolve. This rapid evolution in the nature of work will affect everyone from welders to landscape gardeners, mortgage brokers—and CEOs; we estimate about 25% of CEOs’ time is currently spent on activities that machines could do, such as analyzing reports and data to inform decisions.
