It starts out messy, and then it gets really messy, and then it gets messier, but as people refine the models, the best nodes become more prominent, and with each iteration, the model becomes clearer because people build on top of each other's ideas.
开始非常混乱，然后就变的真的很糟糕， 之后变的更加乱了， 但是当人们推敲模型的时候， 最好的节点们变得更加显著， 在经过每一次的重述， 模型便变得更加清晰， 因为人们的想法互相叠加。
