I tell people we have inverted control with the latest agent concepts. Instead of deterministic code treating LLMs as functions, we have LLMs determining the flow of the app and the interaction with the user. It is much more organic when it is done right and you can gain access to features you never coded. We have been implementing UI tools/widgets to allow a much more interactive experience and it is amazing to play with that idea. This will obviously be part of the standard toolkit of agentic software a year or two from now. The agent stack is just now forming and UI is a core piece of it.
