IMO: It&#x27;s not a threat to humanity, but it <i>is</i> scary. It&#x27;s scary because our entire economic model is based on supply and demand (I&#x27;m simplifying, I know that&#x27;s not completely true). With things like 3d printers, that model no longer makes sense because the supply = infinity.<p>We&#x27;re entering a post-scarcity society, and I&#x27;m super-excited. I hope it comes sooner rather than later, but there are going to be some significant growing pains as we re-adjust.
