So far, it has been smartphones with only recently other devices such as smartwatches and the Echo also offering AI assistants. But are these the most natural points of interaction with AI assistants, or is there a device even more fundamental? Windows 10 is rolling out embedded AI (Cortanna) that hopefully will allow more intuitive interaction with the Windows universe (Word, Outlook, etc.). So we will start seeing AI for computers--and maybe Siri will be more present in MacBooks. As yorak said, I also believe AI assistants will become the predominant way people interact with the digital world. I see companies like VIV disrupting search engines and potentially becoming the next Googles of the world. Just as our FBook and Google accounts are becoming universal online identities and accesspoints into other services, perhaps so too will people subscribe as a utility to their favorite AI assistant, which across devices/platforms, can know the users' preferences and evolve the service.
But again, what is the entrypoint device that will really make AI assistants widely used?
