Java type system is nominal not structural.

While this rant rung a bell at that time, i've always found that this rant was too easy. Java had non public class, annonymous class and import static at that time.

Nowadays, the Javaland has steal lambda and var from Scala, moving away from a real kingdom of nouns (partially, you still need those pesky functional interfaces).

That was great. I read it for the first time. Similar scenarios happen in so many other fields. Some bad idea takes hold. Then schools teach it. Then more people invest time learning it so that they cannot admit it is bad and this goes spreading like wildfire and become sacred...

And then someone discovers that the old way was better and gives it a new name. When I was in school, functional programming was called "programming".
