Uncertainty and fear have enveloped the world. Motivational speakers will probably earn millions talking on the topic of “How to live in a time of incertitude.” High-school graduates worry about how they will do their SATs and apply to places of higher learning, while university and college graduates wonder whether they will find a job in a world that seems to heading rapidly towards economic crisis. Proprietors of small coffee shops are anxious about whether they will be able to reopen once the quarantine is over, programmers—whether orders from large international companies will be cancelled, as the financial stability of their businesses depend on them. One has the impression that today there isn’t a single young person who does not worry about the uncertainty that hangs over us.
