Many programmers and Computer Science graduates are moving towards Data Science and Machine learning hoping for better pay and career opportunity and there is a reason for it. Data Scientist and Machine Learning Specialist have been ranked the number one job on Glassdoor for the last couple of years and the average salary of a data scientist is over $120,000 in the United States according to Indeed. Data Science is not only a rewarding career in terms of money but also provides the opportunity to solve some of the world's most interesting problems. IMHO, that's the main motivation many good programmers are moving towards Data Science, Machine Learning, and Artificial Intelligence.
