Data science is one of the most imposter-filled "professions". It's a recently-established category of worker that falls across multiple disciplines and is very effected by technological progress. I have met "data scientists" who aren't really good at any aspect of it, but they still get by because of the supply/demand and lack of any existing expertise to say "hey, you know, this person we hired is barely competent and just googles everything we ask of them"
