Data Science and Machine Learning are buzzwords with little jobs behind them.

There's work to do around data (databases, logs, analytics, marketing, business intelligence, etc...) but none of it has to do with stats/maths. The realization is quite hurtful for those who wished to pursue data science.

The only field that recruits maths folks is finance, specifically quants, who are doing financial analysis all day. It's only a few roles in a few places and highly selective.
