As the saying "use it or lose it" goes, AI could trigger a massive loss of skills in many aspects of modern living, and introduce significant risks. 

But skill decay in, say, airline pilots could be disastrous. Already, up to 85 per cent of flight time is controlled by the autopilot system, possibly giving pilots insufficient exposure to manual operations.

The United States Navy's reintroduction of celestial navigation to its officer training curriculum in 2017 is another momentous attempt to bring back the old stuff. Celestial navigation is an ancient Polynesian practice of determining one's location on the planet by reading the stars and constellations. The navy stopped teaching celestial navigation in the 1990s because of increased reliance on electronic technologies such as the Global Positioning System and radar. But these systems are increasingly at risk of being hacked and their signals jammed, and stargazing has now become a viable backup for navigation.
