The last such chatbot I used was M-x Doctor. I haven't seen much improvement since then. IMHO on specific limited matters like obtaining a permit, customer support etc. chatbots can go a long way by using traditional methods. I think if we can map the subject in a big decision tree and apply some good-old Bayesian probability, we can achieve a working conversational chatbot.
