Bad optimization is bad. Of course.

  That's what premature means.

  You're missing the point. The point is that in many cases, you should optimize for readability and simplicity first, and optimize for performance only if it's likely to become an issue. If you optimize for performance first, you may well have massively increased your cost of development for incremental performance gains that you could have got by throwing a bit more hardware at the problem.
