Imagine a world where every phone gets turned into a useful digital assistant that can order things for us online via APIs. I wonder if Amazon is ready for this.
It's my belief that the lasting innovation of LLMs will be finally making voice a true first order interface for our computers. "We'll just be talking to them" is something I've heard since the 90s and it seems like we can finally see that reality on the horizon.
This will be the case until we have AI agents that are as intelligent and competent as a top-percentile human personal assistant. At the point where that's possible though, I doubt the future of phone interfaces will be the most interesting change.
Brain to machine signaling interface is the logical step forward if we really want to be faster at input.
The digital assistant will need to be impartial and help in comparison with other similar product. Then again different people have different comparison criteria. Based on context I might be okay with a chinese knockoff while most of the time I might prefer the item that will last the longest.
Due to its size and infrastructure Amazon has advantages of choice, price, delivery and service. No digital (or human) assistant is going to be able to find a better deals on most items and then negotiate for it to be delivered tomorrow, free or cheaply, with a fairly good, no quibble, return policy.
