We also must embrace the fact that data science is in part a craft. Analytical expertise takes time to acquire, and all the great books and video lectures alone will not turn someone into a master. The craft is learned by experience. The most effective learning path resembles that in the classic trades: aspiring data scientists work as apprentices to masters. This could be in a graduate program with a top applications-oriented professor, in a postdoctoral program, or in industry working with one of the best industrial data scientists.
