Not sure if the Rabbit device is the answer but I definitely see why people are trying.
Thing is these AI devices will become actually interesting when they start being observers in your life too and pre-empting rather than the siri style ask and response and that just isn't possible on a locked down OS like iOS.
The answer is absolutely to do these types of products on the devices we already own. There is only one thing stopping this type of innovation and experimentation.
