Yeah, I agree with you on the overfitting, but I think when the dust settles the working uses for it will emerge and the rest will be trashed. To your point, I think its fully open-ended uses such as a chatbot will relatively fade. I predict the real value will come out in converting user-intent in some subdomain into a deterministic set of options. The schedule conversion in the article is a common example of this. If you build these small, domain-specific use cases into a user interface, things just get easier for the user. A big benefit of this is that you already have a ton of context, so the user doesn't have that burden.
