I have to disagree on this. Data scientist is a very fluid and fast changing term. I know companies who now call what would traditionally have been "machine learning researcher", "machine learning engineer", or "research scientist in <any data related stuff - data mining, computer vision, signal processing, machine learning, statistics>" as "data scientist" positions. Because it is sexy, in many places, management and job hunters get a kick out of the term "data science" even if it is actually a renaming of other traditional roles. This book perfectly captures the diverse nature of the term.
