Does an actual, real, problem exist for which the soluton may be to "translate contents of FAQs (actually FGAs [1]) into a conversation-like interface"?
This assumes that the FAQs/FGAs are actually already about what the customer wants to know, which is something that - at least in my experience - never happens.
Or, if you prefer, the assumption is that the content is there but that the customer cannot find it, while it seems to me that what - generically speaking - is missing is the actual content.
Good point, that's why we added analytics where we cluster the most common questions and show you the most common unanswered questions, so you can improve your help pages. There's also a (albeit rudimentary) human handover when the question can't be answered.
