Definitely not meant to be a comprehensive list. It's supposed to be a list that can get you up to speed on the basics really quickly. You definitely don't become an expert data scientist just by going through the list and doing the exercises. If you feel like we missed out on something big or if there's a better resource for one of the items, I'd love to hear your feedback! We're continuously iterating on the list.
It doesn't actually say "learn data science ASAP" on the article. That's just the title created by the poster. The article actually lists resources one can use to prepare for Insight's data science fellows program.
FTA:
"This list was started in the first sessions of Insight as a way to make sure that our Fellows were prepared for Day 1 of the program - we called it "Preparing for Insight.""
