I am looking to change careers and enter Data Science. I can't decide which language to master first. Looking at job boards, Python seems to be everywhere, but R seems to have a presence in Pharma and Finance. If you were starting today, which language provides the best "bang for your buck" in terms of salary and job security?

For a generalist starting out, Python is the safer bet. It is the dominant language in Silicon Valley tech firms and is required for almost any Machine Learning Engineer role. However, if you have a background in biology or economics, mastering R can be a huge advantage. In the Pharmaceutical industry, R is deeply embedded for clinical trial analysis and regulatory reporting. These roles are often less "hyped" than Big Tech roles but offer incredible stability and high salaries. My advice is to check the specific industry you want to enter; Python is for "General Tech," while R is for "Specialized Research."
Do you think the rise of "AutoML" tools will eventually make the choice of programming language less important for entry-level analysts in the next few years?
Python's versatility means you can pivot to software engineering or DevOps if Data Science gets too crowded. R doesn't give you that same level of career flexibility.
That is a very practical point, Margaret. Python is a "career insurance" language because its applications go so far beyond just analyzing data.
Anthony, AutoML might handle the training, but it can't handle the data storytelling or the feature engineering. You still need to know the underlying language to clean the data and interpret the results. The language is just a tool for the logic you have to provide.
