An A100 is about the size of a brick, there is no way we're fitting those 8 bricks in a phone in the next five years, without even thinking about heat management
An A100 HGX server is ~6kW of power consumption (and associated heat), while an iPhone is O(1W). I agree that a 6000x increase in energy density or 6000x decrease in power consumption is unlikely in this decade.
