I think you've answered a different question to the one I was making. I'm not claiming chatbots are a sound business. I'm saying the pricing path follows the Uber/Airbnb playbook: subsidise hard to build the user base, then tighten the consumer tier once the real money is elsewhere. That's the "as intended" bit.

Uber's also a shaky example for "virtually no OpEx". It lost money for the better part of a decade, running on investor-funded rides and driver incentives, before it squeezed either side. That's the pattern I was pointing at: generous now, worse later.

Whether the underlying business holds up is a separate argument, and you've got a fair point there (Air Canada is a good example of the liability risk). It just isn't the argument I was making.
