Tired of hearing the same old arguments and having to try and be interesting in drafting a response?   The Twitter chatbot @AI_AGW is here to help, at least on Twitter.

Nigel Leck is the programmer who created it.    Read Chris Mims at Technology Review for the details.  

It does a pretty good job, too.  Some of the arguments have gone on for days.
