Don't forget though that not all goods are affected the same way. I remember working on a project in the early 1980s. We decided that the future was non-volatile solid state memory and that Intel's new "bubble memory" looked pretty sweet. From memory it cost something like $NZ1000 for 100Kbytes, yes that is K for Kilo, of solid state, non volatile memory. Today a 16Gbyte flash drive costs around $NZ10 retail. So in round terms today we get something like 100,000 times the bang for one hundredth of the buck. And of course the modern product is hugely preferable in terms of speed, size, weight, robustness, power consumption and any other metric you can name. Obviously tech is a standout field, but there are others, air travel for example.
