>when you only need to write two curly braces to create a “dictionary” (of course behind the scenes this is a hash table) many of the nuances of that data structure are hidden from you. You have no idea that accesses are on average O(1) but worst case are O(n).

Well, that is wrong. Single value accesses are O(1) amortized.

Also, Java is a lower level language but I don’t think simply programming in Java instead teaches you this. Either way, it’s the difference between learning how to write programs and learning computer science.
