I'm with you. We've seen a demo, not a real product that people are using. I wish people would temper their expectations a bit. If product development has taught me anything, it's that it's easy to put together a demo to show how well a product can work in the golden path, but once you stray from it, it becomes incredibly difficult to solve all edge cases. With something like conversation, there are lots of edge cases that need to be handled. Once you have a missed edge case, the illusion of reliability falls apart.
