There are so many examples prooving that the type of shallow analysis given in the first answer is pointless. I thought it was finally understood that it is not the idea that matters but the execution. According to this type of analysis, google was doomed from the start, dropbox as well, Android dito, etc. etc.

My advise would be to ignore such type of answer and focus on making something people want and generates traction. The author of the answer is too narrow minded and lacks imagination and creativity.
