Summary:"All (energy) models are wrong, but some are useful." For as long as predictive models of any sort have been prepared, there has been a (sometimes raging) discussion about how accurate they are. Essentially, they're all wrong if you consider accuracy as "matching reality exactly." They can be very useful, however. The challenge is to recognize where and why models diverge from reality and when it matters for the purpose at hand. In other words, how can we maximize "usefulness?"
