Someone once said: our education system should create job creators instead of job seekers. This, plus continuous learning is a new reality.
But we also need to redefine: having a job. Even if you have multiple jobs in your lifetime we see them each as fully employed. Job also implies social security and 35h work week (for some). This system or view has to be replaced. We will work on things more like a project. Different settings, different teams. 5h or 50h some weeks. Together with a UBI or an EBI👍.
One last factor on top of AI:
The rise of the Blockchain will replace the need for (large) companies that have jobs for people. Democratisation has side-effects. This effect might even be greater than the one of AI.
