I’d like to add to that list all the “learn AI” blogs etc. that gloss over the details and show you how to call some libraries to do cool stuff. Everyone and their cat can learn how to invoke some APIs, which is cool, but the reality is that data is hard, and if you want to do good, sound work, you need to have an understanding of the math and fundamental principles behind it.

It might not save you from making stupid mistakes or wasting your time, but at least you will know what mistakes you can - and will - make.
