I wonder if "build it and they will come" is just flat out wrong, or only correct for certain products? Is there anything one can "just build" now and expect some market adoption?

    1. build something noone can live without.
    2. it already exists : market is too competitive
  

You have to build something that doesn't exist and which would be still considered as almost vital.
