Chat as Universal Interface
The conversational interface is AI's most brilliant design choice, leveraging millennia of human communication instinct.
Chat works because humans are evolutionarily built for dialogue—we automatically adjust to each other's linguistic frames, propelling understanding forward through back-and-forth exchanges. Unlike command-line interfaces or GUI systems that require learning curves, chat allows users to interact with AI using the same natural language patterns they use with humans. The simplicity is intentional: by making AI accessible through conversation, companies get usability for free.
"Most text conversation UI's are visually indistinguishable from those of a messaging UI used to communicate primarily with other human beings." — Eugene Wei
