B.It leaves many people worrying about job loss.

参考答案：B
参考解析：
细节理解题。根据文章第一段第二句“While AI offers much promise for the development of smarter and more useful machines, it also fills many with fear of a dull future where millions are thrown out of work, replaced by robots and smart machines”可知，尽管人工智能为开发更智能、更有用的机器提供了许多希望，但它也让许多人担心，未来将会是一个沉闷的时代，数百万人失去工作，被机器人和智能机器所取代。因此，人工智能让很多人担心失业。故选B。
