A massive reskilling will be necessary, not just for blue collar workers, but many white collar workers. (Kai-Fu-Lee, ex-president of Google China).
We need to start experimenting in this area. There are bootcamps & MOOCS for coding, but little in other areas: for example, industry specific knowledge, productivity tools, applications of new technologies on older industries (3d printing, AI, VR, etc).
Sweden has a wonderful model which brings together businesses, labor unions, and workers, working together to communicate needs and retrain as necessary.
