I don’t agree that trying to estimate things is bad as the author suggests. If you are perceptive and want to get better at it, then there’s a decent chance you will. Estimates also help us timebox work. They can help us give an objective view of when we should start exploring functionality tradeoffs. This article sounds like a lot of whining about not wanting to do something because it’s difficult.

I will say I think that holding people to estimates is not fair because it doesn’t necessarily correlate with productivity/value added. When asked for estimates my general rule is: take a conservative estimate and double it.
