3D printers is a great example of a concept that could really push us forward as a society in terms of innovation, but it's not taking off due to lack of profitability.

I wrote a post a while ago about the book The Celestine Prophecy: https://saidit.net/s/conspiracy/comments/3yi3/the_book_the_celestine_prophecy_claims_that_we/ The TLDR is each person naturally emits energy, what psychics call our “aura.” When two people have conflict, the winner sucks away some of the energy of the loser, giving the winner a physical and emotional boost. The reason we have interpersonal conflict is because unconsciously we are all trying to get this boost. The Prophecy is that in the second millennium, the humans will learn how to harness this energy out of the earth itself. Once we no longer need to suck one another’s energy to fill ourselves up, we will no longer desire interpersonal conflict and we will become a peaceful species. The society it describes sounds like what you just described -- people stop being selfish and exploitative and just work together peacefully. I'll be honest, I am holding a lot of hope that the prophecy is real and that it comes true soon.
