That was my first thought skimming through this too. Either every *nix admin who is aware of a few text processing tools is a data scientist, or “data scientists” are just as full of it as I’ve expected.

Just because a tool can be used for A, B or C, and you are an expert at using that tool for A does not imply that your expertise at using the tool for A makes you an expert in B and C.

The whole point of this article is to point out that a lot of common Linux tools can be used for Data Science like work (a significant part of which includes pre processing structured and unstructured text).
