Over 120 million workers will have to be retrained within the next three years due to mass disruption caused by AI and automation. That's according to a new study by the IBM Institute for Business Value, based on input from 5,670 global executives in 48 countries. The issue is not just one of jobs being lost, but the lack of a strong skills base to underpin the emerging technologies, with the institute warning that the time it takes to close a skills gap through training is growing. Interestingly, the report finds that executives see technical core STEM capabilities – along with basic computer and software skills – as significantly less important than they did three years ago. According to the global research, the time it takes to close a skills gap through training has increased ten-fold in just four years. In 2014, it took three days on average to close a capability gap through training in the enterprise; in 2018, it took 36 days.
