I can't think of many things that I would like less than communicating with a ChatBot....
Couple of words spring to mind : Cold, Lifeless, Clueless , Funless, Loveless, Careless, piece of shit...
You know , talking to real people is really not a problem... Even some stuck up, conceited arsehole would be far more interesting to "communicate" with than a very expensive, and almost useless, chatbot.
On top of that, they scraped the text from Social Media websites, how can that be considered as a good example dataset ? Social Media website are usually full ranting and raving rather than any real conversations....
Biting the hand that feeds IT
