So.. I went reading the article, expecting something really ridiculously bro. The article was well written, good references, but yes, uses a few silly conversation samples (for which there were no sexist, racist or homophobic references).
Is it possible that training a bot to speak like that (silly/casual) is more challenging than to emulate a very grammatically correct and stiff style? As such, maybe the choice of conversations was intentional?
My comment was directed towards the OP, who was harsh and didn't provide a proper argument. As I said, it was a nice article and I wanted to encourage others to read it, despite that (flagged) comment.
I see it more often used to mock a male mono-culture and the pitfalls that derive from it (ex: brogrammers). A bit like the term douchebag has become a synonym of 'jerk'.
