Moore’s Law centers around the size of technology as time passes. It specifically predicts that manufacturers will be able to double the amount of transistors on their chips every couple of years.
Wright’s Law focuses on the cost of technology as more units are produced. It specifically predicts that for any technology or product, every time the cumulative amount of units produced doubles, the price of each unit will fall at a steady percentage. In other words, the more we produce of any given product, the less that product will cost.
