>easily replicable probably it was not a good idea after all.

I mean, sometimes the hard work is creating object number 1. There are a crapload of inventions that we look back on and go "why did it take so long for us to make the first one", then after that whatever object/idea it was explodes over the planet because of the ease of implementation and the useful practical application.

I think this statement is marred by the our modern sensibilities that say everything must be profitable or it's a bad idea.
