This figure is self-explanatory and is taken from the December 2017 McKinsey Global Institute report Jobs lost, jobs gained: Workforce transitions in a time of automation. The main prediction is that between 20% and 27% of work activities (measured in units of time) will be displaced due to automation in 2030 in advanced economies. Countries with an aging population will be affected the most. This is only one part of the equation. The other (missing) part is the number of new jobs, in order to understand whether they will be able to offset the displaced jobs. Nobody knows the answer because it depends on the structure and the choices of institutions.
