There's a robot apocalypse coming, but it's likely not going to result in the loss of billions of human lives. Rather, it's our livelihoods that are at stake. For some vocations, signs of a paradigm shift are already here. The HRP-5P humanoid robot is designed to be a drywall-hanging machine. It's slow now, but it's capable. Sooner or later, it'll be fast enough and cheap enough to make skilled construction labor a thing of the past. My Grandfather, who spent the better part of his life building churches, homes and movie theaters, would have shit a brick were he alive to see this.
Have no doubt, no matter what you do for a living, that similar appliances are on their way to make our daily toil a redundancy. Society's going to need to learn to adapt–fast.
