so it's not the websockets vs polling, but the shift to stateful backends which makes the difference.

We made SSE to replace WebSockets. Now you have to irvent a concept which makes sure that assigns a container for you and "flags" it as yours, so it orchestrates the traffic always to the right container, then the trainee says "lets just switch to websocket". OpenAI and Theo: "Brilliant. Why nobody thought about that?" Jesus Christ, what am I watching??
