Low wage labour in developing countries who have not had a chance to develop higher value jobs or industry will be hardest hit by automation. The percentage of job loss is closer to 70% vs the 40-50% average seen in developed countries.

It will be the cheapest, but also the most imperative action to focus on accelerating the developing world’s productivity and skill levels before they literally and figuratively work themselves into death and starvation
