This, of course, is why further technological advancement in certain fields should be banned, and certain areas of current technology actually scaled back. Both are, of course, largely impossible, thus the only things that can actually stop this are a devastating pandemic or a nuclear catastrophe (or some other disastrous event). These are not very palatable, so it appears that humanity is screwed just about anyway you slice it. Either we'll be butchered by the robots, or we'll be butchered by the natural world. Ah well, there's still Heaven to look forward to.
Wouldn't it be preferable to implement policies such as an earlier retirement age rather than luddism?
