If agents are async, is streaming still important? I think the useful set of interactions with an async agent are pretty limited - you'd want to stop, interrupt with a user message, maybe pause, resume, or steer with a user message?

All of those can be done without needing streams or a session abstraction I think, unless I'm misunderstanding.

Yes it is. But it's nice you've convinced yourself I guess.

What is this, if not a product pitch:

> Because we’re building on our existing realtime messaging platform, we’re approaching the same problem that Cloudflare and Anthropic are approaching, but we’ve already got a bi-directional, durable, realtime messaging transport, which already supports multi-device and multi-user. We’re building session state and conversation history onto that existing platform to solve both halves of the problem; durable transport and durable state.
