for sure there are several non-trivial factors that helped this dramatic scaling example: * ability to isolate a fairly universal need that can be solved in full by software. as soon as you have to customize to meet cultural/political fragmentation you start losing orders of mangitude. once there is a need for a "human in the loop" to provide person-to-person support the "magic" is pretty much gone * ability to deploy across vast numbers of devices. this universal canvas is generally not the case. exceptions being e.g. web standards or having an oligopoly in mobile devices still, despite all those caveats, software is a completely different game at its heart. in principle it scales to infinity and it becomes a whack-a-mole game to figure out which factor will land things back to reality
