Yeah - my class covered the language and meanings of the terms in a couple days. It's wonderfully simple. Which makes it hard in the same ways programming is hard - arrays are trivial! People still screw up bounds checks routinely!

Figuring out what you want, and understanding your data well enough to know what's viable and what's nonsense, is infinitely harder. And it changes every time.

Getting good at that part is "expertise" in a nutshell - gradually learning what strategies work and when, and getting better and better at your guesses. That takes more than a few weeks; that's an entire career.
