At first I laughed and grimaced slightly. I thought about arguing about SOA but then luckily I remembered a building architect friend of mine raving about concrete.
He eulogised about how strong, elegant, durable, flexible, economical and beautiful it is. It enables structures and forms that were previously unimaginable. Construction costs are significantly lower because of concrete, and it comes in many forms. Concrete is the backbone of modern construction, and it continues to evolve.

True, concrete has spawned some monstrosities, but it produces structures and buildings that delight and revolutionise the way we live.
On the other hand putty: It fills hairline cracks. Is great for children and artists or for taking imprints of keys in spy movies. It is useful for keeping glass in place in old buildings, and has been used by Nick Park with great success. Also, unless you keep the lid on the jar it turns into a brittle blob.
