Is chat the primary or secondary use case of an AI system?

If it's the primary, then everything is about chat, and every so often non-chat like experiences (e.g. little artifacts or bits of software or documents) sprout up inside the chat.

If it's the secondary, the system is about software, documents, and some of those interfaces revolve around chat… but not all of them.

Does the data live in the chatbot or does the chatbot live amongst your data?

Is it one big chatbot or is it dozens of little chatbots amongst your other experiences?

This software layer is so minor in today's nascent systems that it's hard to see it.

But it could be that chatbot is merely the first app in AI, not the most important one.
