This statement isn’t to say that you can’t make a living as a data scientist; it is more a critique of the logistics behind the statement.

In a way, it is a lot like the word DevOps. Is DevOps a job, or is it a behavior?

In looking at job posting data and salary data, it appears the job market is saying there is an apparent demand for actual ...
