I used to work as a data scientist. This title is not what it should be, I witnessed first hand how business thought data science is the magic that they would be able to rely on to consistently deliver impossible work. There are so much junk that gets shuffled our way and have the expectation that gold be coming out of them. It feels like the financial bubble of 2008, except it's with the inflation of the position and the 'clout' of data science.

There's nothing wrong in data science itself, just like there's nothing wrong with mortgage. But the current trend of software engineer/ non-software engineer moving into data-science is not sustainable. Things will break before it's fixed again, I've always considered myself a software engineer first and foremost, just with some extra machine learning/stats knowledge, and I'm glad to be out of that position now as it looks like we're in for a reckoning soon.
