I too am critical of data science, but I think that this is a bit unfair. The scientific part could be called just 'statistics'.
Not everyone is doing regression and classification all day.
The above were studied in the Computer Science curriculum at my university. I work with a statistician, like someone with a degree in mathematical statistics. They know nothing about any of those.
Yeah, some of them are doing unsupervised learning (recommender systems) too!
I dunno, I personally think we'd all have been better off if we'd called it statistics as at least then people would realise that the field wasn't created yesterday.
