Imagine a project where no testers are needed because no bugs are created. Is this even possible? Is it something to strive for?

We are a young and immature industry. This is obvious from how many projects are running late, over budget, or simply canceled. We try to run our projects as if we're building bridges, and we like to compare our industry professionals to surgeons.
