Nonetheless, these new innovations could prompt dim goo, in which self-repeating, crazy robots expend all matter on earth while copying themselves, either intentionally or inadvertently. This theoretical situation is known as ecophagy ("eating the earth").

Computerized reasoning - some future calamities may lie in the unanticipated results of innovation. Some time or another soon, it has been proposed, a minute may come when PCs and robots get to be more brilliant than people. This has been called "the Singularity", and it might turn out to be entirely risky for people if machines ever build up a high level of insight and choose they no more need humankind to benefit their requirements.
