My question, OP, would creativity end wars or it just makes it spread like wide fire across regions where wars wasn't happening?
Look at the weapons of mass destruction such like the IBM, it was from creativity that it got invented and similar with a host of other mass destructive weapons the world knows today. So it's really not about creativity but a question of what you're creating. Is it to help humanity make lives easier and much productive or about destroying and empowering nations to war themselves.
Creativity is part of human nature and I don't know why the OP didn't notice that. Human creates war in order to benefit from it and not lack of creativity that causes all these wars or the atrocities. The selfish interest of human is what causes it. Satoshi is creative.
