I agree that knowing what to build is a real skill and one that is not easy to get right. Sometime you have to make a judgement call on what the market really wants and build it.

Unfortunately not all problems are amenable to “stubbing out” with human labor. With my product every new feature has to be built first and then introduced to the market - sometime they stick and other times they fail to get used despite being really great (customers aren’t always rational).
