There was no way to get to a smartphone without cumulatively trillions of dollars of investment in silicon, software, network rollouts, and so on. A person with 100 billion in 1998 could not have bought one despite it being a decade away for the entire population.

A mobile phone today is a world away from Dick Tracy's radio watch, or even a nokia 3210 on a digital network in a western city
