With all due respect, Two chatbots in a chat with each other usually never fare very well. There is little done by them to nudge or even attempt to "steer" the direction of the conversation the way most humans do or can do. There is no leading question or open-ended dialogue.
Often times they will get caught in a loop, parroting phrases or sentences back and forth to each other since nothing "fresh" or new has been injected into the conversation forcing them to think about alternative answers.
This is very evident through your bot vs bot example, especially from 8:00 to 13:00 approximately, I heard, "The Capital of Massachusetts is Boston" repeated back and forth until I finally heard you interrupt them and tell them to stop repeating...blah!! Funny but agreed, it is annoying. 17:00 was especially funny!! Never say that %@#$ again!! HAha!! Good stuff!
I sort of thought you were going to use a set of prewritten questions or statements then type and show each of their text responses.
That way you could help steer the conversation & topic but also observing the results from each bot. Kind of a scientific or more controlled experiment.
Hey man, it's all good. We do appreciate your efforts and honest evaluation!
