This kind of statement always makes me feel funny. It's true that algorithmic complexity is the most important part, you always have to measure, and micro optimisations are often not worthwhile. But this type of statement seems a lot stronger than that. I'm a graphics programmer working in game development and most of my time is spent on our performance task force. I spend a lot of time thinking about the performance impact of things I write and revisiting things I've written to improve their performance. My job would have been easier if more people spent a bit more time considering the performance impact of their solutions, as well.
