5 years is fine for such a project. It will 'take off' if it finds a practical use case. If they start making Androids based on this, it will 'take off'. If Tesla, Ford, Volskwagen use it in their cars, it will 'take off'. etc.. I don't have nearly enough insight to know one way or another, but G is a big company and if they want to do something they will. My point is, the 5 years and no traction isn't necessarily indicative of that much.
