Vertical-specific or a mega bot?

Where will the future take us when it comes to the bot's capabilities? Will we continue to focus on vertical-specific conversational UIs, as we have seen in our examples of banks, travel, and e-commerce bots, or will we turn to the know-all intelligent assistants, that can do everything? Will we be able to create that "mega brain" that will be able to differentiate between use cases from various aspects of life and provide us with a one-stop shop for all our needs?

As I stated in the last two chapters, I believe we will gradually move from the domain-specific to the "mega brain" in the next decade. The concept of personal assistants, such as Siri and Alexa, will expand to allow cross-application interactions and recommendations. This highly complicated task requires lots and lots of data to be able to deal with our AI-hard obstacle, but it will probably be achieved as those solutions continue to evolve.

It also seems, that, in order to get to that last point...
