Why Your AI UX Is Broken (and It's Not the Model's Fault)#

- Why: The transport layer (HTTP/SSE, a one-way pipe tied to a single connection) is the hidden constraint on next-generation AI UX — interruption, resume-after-disconnect, and multi-device sync are infrastructure problems, and the emerging answer borrows from durable execution.
- What: The pattern of the session as a durable, shared resource independent of any single connection, device, or agent instance, enabling resumable streaming, live steering and interruption, multi-device continuity, concurrent interactions, and human-in-the-loop handoff — capabilities already shipping in leading AI products.
- How: Decouple session state from the streaming transport, so connections can break and devices come and go while anyone who joins catches up automatically; demos on real code, independent of model or framework.
- Where applicable: Teams building AI product frontends; a general architectural pattern, not org-specific.
