Yes, that is not untrue. However, when you talk implementation, a major part of operations is - "what can people understand and act upon in a coherent way". Your bottleneck to most system implementations is the processing capability of the people. Therefore, in practice, less accurate but simpler models end up performing better. Re: Newton - I am not denying complexity. I am simply saying recognising basic truths, honoring them to the extent to which they deserve, making them the foundation for all further activities/undertaking. For ex - Rickover dealt with super complicated projects, but how he dealt with them is based on utterly simple principles; so simple that people would outright reject them, until they see the results he achieved. One could say the same regarding Lee Kuan Yew's work.
