The Chat UX is a vestige of when LLMs responded quickly.

You'd send a message, and then while you were watching get an answer, starting instantly.

Now, with thinking tokens and sub-agents, it will likely take awhile for the answer to even start streaming.

So now it's "send a message, come back later."

By the time you come back, you'll likely have forgotten where you were.

It's an OK UI but it doesn't feel like the optimal one.
