This really feels like the end of an era. I got my start going through the MITx computer science and probability courses. I wouldn't be a data scientist today if I didn't have those resources available. I now understand how to self-learn difficult subjects with textbooks and online lectures but I really appreciated MITx's commitment to making rigorous courses freely available.
