Exactly. These "I built a clone of X in Y hours" posts seem to imply that a website or a mobile app are what makes a successful company. In reality they are just the tip of the iceberg. What you don't see are the countless hours of hustling, the distribution deals, the marketing, the organic growth of the brand, etc, etc.
It could be like saying: "hey, I just built a clone of McDonalds; I made a burger with fries."
