Best Online Classes for Job Skills

In 2017, people flocked to online classes about artificial intelligence, cryptocurrency, and data analytics. In 2018, expect more of the same, say leading online-education providers Codecademy, Coursera, edX, and Udacity. In response to a request from MIT Technology Review, they calculated their most popular courses of the past year and revealed which topics they think will lure the most students in the next. More than 29 million people have registered to take classes at Coursera, an online platform that hosts more than 2,000 courses from universities such as Stanford and Yale. Nikhil Sinha, the company's chief content officer, says many who enroll are "looking for a leg up in their careers" and gravitate to the platform's "cutting-edge tech" courses.
