There are 1000s of SHOW HN. But a fraction of them get attention. So does that mean the idea was worthless and the person went ahead spending time building it? No, the person who builds always finds it fascinating. It may not become a hit. But you can't say the idea is worthless. It is a lottery. Only few make it. The magic is about doing the best you can on the idea you like and leave it to the audience to decide just like a Movie.
