His finale after all that was clarity. He suggested it'd be better to aim for being a software writer more than a software engineer, and to focus on writing software well.
As others have pointed out, he did argue that unit testing is sometimes a waste of energy when taking to the extreme. However, along with that he pointed out that he believes system tests are in fact important, and his take is that they're much more important than 100% code coverage in testing. Does your whole system work?
