  Athena 2.0 is an Alexa Prize SocialBot that has been a finalist in the last
two Alexa Prize Grand Challenges. One reason for Athena's success is its novel
dialogue management strategy, which allows it to dynamically construct
dialogues and responses from component modules, leading to novel conversations
with every interaction. Here we describe Athena's system design and performance
in the Alexa Prize during the 20/21 competition. A live demo of Athena as well
as video recordings will provoke discussion on the state of the art in
conversational AI.
