Why becoming a data scientist is NOT actually easier than you think

TL;DR - You can take the ML course on Coursera and you're magically a data scientist, because three really intelligent people did it. I'm not claiming the people referenced in this article are not data scientists who score high in Kaggle competitions. They're probably really intelligent people who picked up a new skill and excelled at it (although one was already an actuary, so he is basically doing machine learning in some form already). Here is my problem with it - being a data scientist usually requires a much larger skill set than a basic understanding of a few learning algorithms. I'm taking the Coursera ML course right now, and I think it is great!
