The Internet and smartphones have changed the world and how we relate to each other. Instead of meeting in person, we increasingly interface through handheld devices.我們越來越多地通過手持設(shè)備進行接口.In a sense(在某種意義上), real people are being removed, replaced by technology and virtual friends. Some people even say that they prefer to confide in（對...吐露真心話） their virtual friends rather than their real friends!
AI, or artificial intelligence, is another technology that is highly disruptive(破壞性）.With AI, smartphones and other devices will have even more capabilities. They will be able to converse with （談心）us and tell us jokes. They may even become personal tutors, and replace our online human tutors. They will be able to this because they will have access to our life histories. They will know what kind of problems we have, our preferences, and any content we want to learn or practice. They will be able to adapt to our needs and be available at any tine. And all this will be at less cost than using a human.
In fact, the substitution(代替物） of AIs human labor has the potential to transform our world. Experts warn that smart machines may cause widespread unemployment. Many workers will become redundant（解雇）沟涨，replaced by machines that can perform cognitive（認知） tasks better than people. An even greater danger is that they will develop personalities and become more interesting than people. Work is already underway（在進行中） to produce AI companions for lonely people. Are these developments something to worry about or something to welcome? How are they different than developments in the past, such as the industrial revolution? Cars replaced horses; machines and industrial robots replaced factory workers. Since the shift to AI is inevitable，(不可避免的）the challenge for policy makers will be to help existing workers acquire new skills. Future generations must be prepared for a workplace populated by AIs that will continue to develop and take on new tasks. Are we up to the task?
