I have a suggestion for people who are very pro unit testing for understanding people who do not test as much: try working in areas that are traditionally light on unit testing. For example, graphics, multimedia, and games. People write stuff in these areas all the time that still work, despite minimal automated testing. There are other paths we might take, Frodo.
