The AI travel agent is trivial to solve though. It's the same as the human travel agent. Put the plan and pricing together, then give it to the user to sign and accept. Do it in an app, do it in an email, do it on a piece of paper, whatever floats your boat, but give them something they can review and accept instead of trying to do everything verbally or in a basic chat interface.

I'm not disagreeing with the "needs to work deterministically" -- there is a need for that, but this is a poor example. "Hey robot, plan a trip to Mexico" might still save me time overall if done right, and that has value.
