Just playing around with the search terms from that second linked article is also interesting - it would appear that many terms ("machine learning", "data science", "predictive modeling", some others) show that Amazon has the largest number of job listings from a single company - for "machine learning" Amazon shows 1706 listings out of 12499 or almost 14% of all listings . . . The way Amazon also pops out in other data science term searches is also interesting - at least in their job listings, Amazon seems to really be attempting to slurp up candidates with deeper data and stats skills.
For some time I have been somewhat cynical about data science. My impression has been that much of what has been pushed as data science jobs is thinly veiled data reporting gigs (just plain old business intelligence). While I still think data science is over-hyped, I think I need to reconsider just how critical it will be as a knowledge base or skill set. While there may not be a large number of deep learning jobs out there, the expectation that a data hacker can be expected to perform a linear or logistic regression against a set of gathered and cleaned data may be closer to fizz buzz than I previously assumed.
I am teaching an introductory programming class (using Python) this semester and students are definitely focused on data science as a career track.
