The Edsel and New Coke didn't fail because of entropy, they failed because the information used to create them was faulty; in that context, as you intimate, <i>information</i> constitutes . I'll concede that entropy is a consistent factor, and that perhaps with more frequency than we comprehend insufficient energy - i.e., information - permits entropy to become a primary influencing factor.
