You do need to be able to understand nonstick coating is unhealthy and not magic. You do need to understand your options for pan frying for not sticking are a film of water or an ice cube if you don't want to add an oil into the mix. Then it really depends what you are cooking on how sticky it will be and what the end product will look like. That's why there are people that can't fry an egg, people that cook, chefs, and Michelin chefs. Because nuance matters, it's just that the domain where each person wants to apply it is different. I dont care about nuance in hockey picks but probably some people do. But some domains should concern everyone.
