Almost There

Is there such a thing as the uncanny valley for all things? What is it called?

When a design or idea approaches a point where it is almost perfect, or almost where it needs to be, the problems that once were hidden by ineptitude now seem to be glaring and acute.

Previously, there was no mention of these problems. They were non issues. However, they have the possibility to become show stoppers once they are brought to light.

How much weight to give these if they have always been there? Do you hold up, or launch, and plan it iterate them out? What framework exists for evaluating a problem’s current relevance?
