Programming changes practice quickly and often because it's cheap to do so compared to physical engineering which is slowed down by execution time, high materials cost, and sunk costs. The interesting question is this: would other engineering pursuits (say civil) have just as much chaos and lack of authoritative practices, if changing practices would be equally fast and cheap for them?
