It is a common and appealing idea that good ideas always start with ridicule and resistance. It is an appealing fantasy especially for the great many people who like to imagine they are very clever but are not. However, it is important to keep in mind that for every crazy idea that ends up working, there were 999 crazy ideas that were just that, crazy.
Some amount of resistance to crazy ideas is appropriate. If the idea works the resistance will be overcome eventually. If we accepted every crazy idea enthusiastically a lot of effort would be wasted.
