So, what should we be teaching? Many pedagogical experts argue that schools should switch to teaching “the four Cs” — critical thinking, communication, collaboration, and creativity. More broadly, they believe, schools should downplay technical skills and emphasize general-purpose life skills. Most important of all will be the ability to deal with change, learn new things, and preserve your mental balance in unfamiliar situations. To keep up with the world of 2050, you will need to do more than merely invent new ideas and products, but above all, reinvent yourself again and again.
