Nice! Yeah I think it has potential for specific kinds of applications. Text-based games are a definite yes. I couldn't agree more with your point about user education. I know a lot of friends who don't even know all the amazing things Google Now can do just because there is not interface to explain all the features. Siri has a "what can you do?" feature but even then, it's very limited. It will be interesting to see what developers and UX professionals do to improve the state of bots.
