This is actually a really good summary. I also agree on learning Smalltalk to learn OOP since it has a really easy syntax, you can deep dive into implementation details if you want to easily and it enforces some best practices like setter and getter instead of giving you the ability to just declare members public. I learned Java in University and switched soon to Objective-C and it took me a while to see reasons behind getters and setters especially since I worked only in small teams on short living projects at that time. Also s Smalltalk is purely OOP so you won't get distracted by numbers and bools behaving differently. And finally it gets you to think in data structures thanks to the collection methods.

Yup.

Getters and setters only really work in programming languages with good metaprogramming support. In Java and Objective-C, they're ungainly and awkward. In Smalltalk and Ruby, they just kind of happen.
