I think this is unfortunately since AI should really be a longer term sustained and responsibility development. However, media tend to like space race type of short term eye balls. Speed isn't usually sustainable.
However, the way I think about it is that people respond better to different way of communication, and knowing a person's preferred styled of communication will be helpful in helping a person open up and get to the root of issue.
It helps in a way that the chatbot knows more about the person's personality than people may have realized. And that is helpful it comes to therapy communication and state of mind. IMHO
Many good points, but this may also result in a proliferation of more "funded/established" AI choices or many more open source choices, making this field more competitive and less efficient. And that could drives up the bubble more
