Future software will be built from three components—storage, models, and agents—replacing traditional layered architecture. This shift means developers must rethink how they structure applications, with AI models handling logic and interfaces rather than hand-coded layers.
This paper argues that software architecture is undergoing a third major shift—from instruction-based (Software 1.0) and data-driven (Software 2.0) systems to context-and-reasoning-driven systems (Software 3.0).
