The author claims that he is a professional developer, while bashing at a programming language (Ruby) because he wanted more abilities from an ORM (AR) of a web framework (Rails).
He thinks that DattaMapper is trending, when it's clearly not(!!) and doesn't know Sequel (another popular actively developed ruby ORM). Hence it's easy to deduce that he doesn't have a clue about the landscape he is talking about.
Yet he is bashing Ruby as if it's hard to write a module with a couple of complex, custom-made raw SQL queries.
