According to Ars Technica, Vinge, a professor and computer scientist who was well-known for his hard science fiction novels such as A Fire Upon the Deep and Rainbow’s End, passed away yesterday. A truly excellent author, he postulated that AI will one day surpass the understanding of its human creators; he described this singularity theory in a 1993 essay. But it is probably for his far-reaching and absorbing fiction that Vinge will be best known.
