I think it is more a matter of people not understanding their tools.

React UI? Smalltalk already had Observer and event messages.

java.util.Observable exists since version 1.0.

Interfaces are lousily based on Objective-C categories, and the first edition of "Component Software: Beyond Object-Oriented Programming" using Component Pascal, COM, Java was published in 1997.

The second edition added C# examples.

Which are concepts that now everyone is discussing as Entity–Component System.

Our field would be much better if there was less pop culture and more book/paper reading.

EDIT: forgot to add the publishing date
