This is my beef with chatbots in general -- it is the rare conversational interface that has any advantage over a GUI beyond its novelty.
Fast forward another 3 - 7 years and users will be wondering at the marvels of a chatbot where one can simply click on the picture of the action they'd like it to perform! Perhaps entire menus of actions will be presented, in horizontal or vertical strips inside the chat interface... these actions will of course be represented by hieroglyphs expertly designed to convey just what they do and no more, to as cross-cultural an audience as possible. Maybe we'll call them icons or something.
You mean like the current functionality of WeChat, Telegram, Kik and FacebookM?
The problem with x.ai is that it attempts to replicate the annoying experience of dealing with someone's idiot secretary, not that it's text.
