Perhaps it is the illusion of communication with a human (if the bots can handle variable expressions for the same concept - e.g. people can say the same thing many different ways) that makes this appealing. I don't have to click, which would mean I construct a concept in mind and I then convert that to the correct expression provided by the service. Integration of simple bot support is a first step as AI/ML + NLP evolves to support greater complexity.
