As a practitioner with over 30 years of experience in the field, the discipline of data science has evolved dramatically. As I have discussed at length in previous articles and in my book, the approach and process in conducting data science exercises has not changed. 

Yet technology has transformed the discipline in that many tasks are now being automated thereby allowing the data scientist to focus more of their intellectual energy as problem solvers. At the same time, data access and processing have increased to the point where analysis can now be conducted on data which was previously inaccessible.
