Seth speculates that frequent buying cycle force companies to updates products such that consumers maintain brand-loyalty.

For example, while the operating system of the car has not changed in 100 years, every couple of years many of us choose to start over and buy a new car anyway. At this point, a consumer can switch brands, forcing the car companies to create something we think is better.

Meanwhile, operating systems have maintained largely the same UI and UX from the start because we simply do not have many choices.
