As the saying goes, anyone can build a bridge that lasts forever. It takes an engineer to build one that lasts fifty years.
It remind me of the quote from Blaise Pascale:
"I would have written a shorter letter, but I did not have the time."

The idea that you need expertise and experience to produce something efficient and refined that fit perfectly the need that it fulfills.
Building a forever bridge would be challenging, especially for 5bn yrs in when the sun expands.
