The LLM is just calling APIs though, if the LLM can do it then it should be exposed to the user. Why have the middleman.
in that medium, llms are so much better than old phonetrees and waiting on hold
additionally for many use cases it's not feasible from an eng standpoint to expose a separate api for each entire workflow, instead they typically have many smaller composable steps that need to be strung together in a certain order depending on the situation
its well fit for an llm + tools
navigating ux is still difficult in 2026
the average hn user is leagues above what the average customer or even smb knows about tech and ux, just not realistic for them to redesign their apis
