My first role as a software developer was writing an elaborate chatbot that worked as a document retrieval and recommendation system that would conversationally collect the prerequisites to running SQL scripts. Many months in we added shortcuts to the system that essentially turned it into drop down menus for users who didn't want to talk to a chatty personality to get work done.

I loved ChatScript and filling templates with data retrieved through fact-triples tho, hope I get to work with it again someday.
