>”There probably won’t be a technology that has 10x greater scale than smartphones, as mobile was 10x bigger than PCs and PCs were bigger than mainframes, simply because 5bn people will have smartphones and that’s all the (adult) people.” Why is the presumption that the next technology is limited by the number of humans?

A technology that significantly changes everything can easily move the entire economy to the point where everything depends on it and everyone is buying it every day (think electricity).
