I wanted to get the community's opinion on how current the coursera program is. Would it help to complete it now given most of the videos seem from 2013/14 era? I am not at familiar with manipulating big data, so this seems like a good place to start. This is purely an effort to understand available methods to work with extremely large datasets and purely out of personal interest. However, I would like to learn the latest technologies or atleast something that will setup strong foundations.
