To be an engineer is to know the expected system requirements and build a product that is extremely optimized for the system requirements.

There's a saying that I think fits very well here: "Any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands."

You don't want a bridge to cost 50 years and quadrillions of dollars to build, you want a cheap bridge safe for the next 50 years done in 2 years.

I would not call the resulting bridge "bug free", of course.
