Dustin Curtis makes an interesting observation on how some technologies grow to become personality-defined choices once they mature:
I think the same thing is happening right now in the computer and mobile devices industry. Computers and phones have historically been sold based on performance, screen size, and battery life. The slow march of technological progress through the 1990s and 2000s was obvious to anyone who knows the word “megahertz”. But in the past couple of years, I think we have finally reached the 1945 equivalent in automobiles: all devices sold today can do everything any reasonable customer would want. The computer is now feature-complete. Almost all model segmentation is now based on the personality of the customer.
