A sabbatical is a legitimate option for career training. This is the only time a person can learn how to fill in unstructured time. Doing so develops skills in how to create jobs where none were defined before. The key element of extended absences is the completely unstructured time. Things that do need to be done can take much longer than normally would be allowed in a work setting.
The freeze dance game is an analogy of what lock down subjects to young people. In that game, someone plays music that everyone enjoys dancing to. When everyone starts getting well into their dancing, someone stops the music and everyone must freeze in their position. Anyone who continues to move is taken out of the game, even if that movement involves catching ones balance. When translated to real life, it is most hazardous for the younger generations.
Much attention is spent on the job-loss implications of introduction of automation to improve productivity. Meanwhile, automation is also used for job-preservation of older workers in outdated yet still essential practices, and this too has some unfortunate implications for the future. Eventually the simulation of an earlier age will fail catastrophically in the fact that that age no longer exists. Alternatively, eventually we will run out of older workers who can work in that simulation.
