As a result, I suspect most people will primarily use the first bot they find useful, rather than employ a bunch of different ones for specialized uses. One, because today’s bots just aren’t all that differentiated. And two, because to the extent that they can become differentiated, it will likely be because you’ve agreed to share lots of personal data with them. And I can’t imagine most people wanting to type or upload lots of personal data to more than a small handful of these companies. That’s not to say that we won’t use AI features dozens or hundreds of apps — I’m confident that we will. But when it comes to a text- or voice-based interface you use to ask any question you would ask a search engine, coach, therapist, or personal assistant, I still can’t see why there would be more than two or three big winners there.
