There are multiple ways in which technical innovation can spread out, probably the two most common are: something expensive gets cheaper and cheaper as it gets more popular, which means it starts as a luxury or relatively exclusive product. Second, it’s a cheaper way of making something, and as the technology progresses the products are more and more advanced, and increasingly expensive versions come on the market. Smartphones are an example of the former; originally expensive (and some models still are), they scaled various technologies like small cameras and GPS units, dropping prices for these components, until we now have $50 smartphones, even without a data plan.
