The author is way off base in saying software engineering is about assembly rather than discovery. That's only true of the lowest-skill non-innovating software shops, and even then, developers are constantly having to discover how to use the new tool of the month.

On an unrelated note I don't really buy into the idea of data science as a distinct thing from computer science.

It was all hype. All of it. I enjoyed learning about data science, but in the end, there were no jobs I could actually apply for and realistically get. I also don't think they were providing the big wins for the company that would justify what they were getting paid. Again, all hype.

Data science is a horribly overloaded term.

Ask a databases person and they will tell you about ETLs and relational joins. Ask a statistician and you will hear about estimators and the bias-variance tradeoff. Ask a social scientist and they will tell you about experiments and causal inference. Ask a CS theoretician and they will mention streaming algorithms and probabilistic guarantees. Ask a machine learning person and you will probably hear a lot about prediction and stochastic gradient descent.

The approach that will breed the best practitioners is an interdisciplinary one; a great example is UBC's program: https://masterdatascience.science.ubc.ca/program/courses. And also future positions that separate the roles of data janitor, data analyst, machine learning engineer, and so on. There is a huge difference between what Facebook's Core Data Science team does and what most companies call "data science", which is sitting on a huge pile of poorly aggregated data and having little idea what to do with it.

Most importantly, data science has to be thoughtful and part of the engineering process, and can't be done after the fact with digital trace data. It's a lot easier to run experiments than it is to do statistical gymnastics with observational data.

The dissing of PhDs is unwarranted. Gross over-generalization. People being skeptical of ideas in a peer-review sort of way can be both good and bad. For example, the assumptions and claims of this article can do with a substantial amount of skepticism. Perhaps someone should express skepticism and view this article with the peer-review critical eye that he mentions.

I am reminded of climate-change skeptic articles that say “hey these scientists know nothing. See today it’s 10 below zero. Common sense! No global warming.”

This is an article making baseless generalizations that all data science is failing in Silicon Valley, and that the true need of a company is to hire a "data strategist." Unsurprisingly, the article is written by a self-proclaimed data strategist.

This blog post would be more compelling if there were citations or even general context backing up the authors pretty wild claims ("the vast majority (we are talking 80-90%) want to leave their current job", "failure rate of data science teams is over 90% right now", "the top 5 data scientists I have ever worked with, only 1 had a PhD").

As a data scientist working for a relatively well known startup in the Bay Area, I don't dispute that there are problems in this industry. There are many under-/un-qualified managers running around (I don't know if that's a data science specific problem, or if it also applies to much of engineering as well). There are ICs and teams that have trouble producing industry-applicable work because they're too academically focused. There are also business-driven teams that have trouble producing quality/reproducible work because they're too business focused.

That said, the claim of 90% failure is ridiculous on its face. Having another MBA put together a powerpoint presentation about a company's data strategy isn't going to suddenly solve the actual issues in data science.

A working knowledge of some basic stats, access to some decent tooling, a good working knowledge of what the organization is trying to accomplish and the ability to persuade and lead based on findings will likely move the revenue needle much more for most companies than a pure "data science" role.

The trouble is of course we don't have a good name for that role, so it's all "data science".

probably some realization that 99% of their actual job is ORDER BY, GROUP BY, SUM...not a bunch of cool math scrawled on a whiteboard I tried warning people off of this field given that they would be doing sql query monkey work and drawing simple line charts...most definitely not an upgrade from software development like it was sold as

They’re probably in the wrong company. Are you suggesting there are isn’t an explosion of jobs and applications requiring advance math and machine learning or statistical inference? If so you are off the mark.

Totally depends on what problem your trying to solve, what tools your employer have setup, and what data science you know how to do. The field is still not very mature, but as the tools get easier to use and companies understand how they can solve problems using machine learning and data science, and data pipelines are thought of at the beginning of projects, it will be a lot easier to apply more sophisticated techniques.

As someone near graduation with a PhD in mathematics with research focusing on machine learning / image processing and beginning the job search, this didn't leave me feeling very optimistic. Is this a problem of not setting proper expectations for a role on the company's part or not fully understanding the expected duties of the position before hired on the data scientist's part?
