I used to think that when 3D printing got to the point of printing at the molecular level, we’d be able to pass into a post-scarcity phase of society.  As with the Start Trek replicators, people could just print anything they need; food, water, clothing, televisions, etc.   

What I didn’t realize at the time was that we’re already living in a post-scarcity world, we just have a distribution problem...
