The author should mention Smalltalk to talk about pure OOP. Not mentioning Smalltalk means the author didn't really researched the pure OOP. The author just tasted some OO style languages. I really don't understand how can the author argue about drawbacks of pure OOP with Python (which is more like procedural) or Scalar (which is more like functional).

Also in the middle of text, the author frequently mention most OO langauges which is nothing related to topic - extreme, pure OO language.

Mention about Haskell is pretty agreeable, but that drawback is already published on Haskell website, and that's why Haskell support impure operations.

I don't understand how can a Ph.D person can write this poor text.
