Vernor Vinge, father of the tech singularity, has died at age 79 [arstechnica.com]

I had an opportunity to talk with him several times, and always enjoyed our conversations. He was down-to-earth and liked hearing contradictory ideas, which I, as a singularity/AGI skeptic, was able to easily provide. He liked a good laugh.

Vinge invented the idea of the Singularity, though Ray Kurzweil gets credit, and the idea has long antecedents in occult beliefs. He wrote many good novels and stories, and at least one brilliant novel, “A Deepness in the Sky.” His 1981 novella “True Names” pioneered the concepts of cyberspace and virtual reality, and anticipated the 2020s practice of “doxxing.”

He was local to San Diego, and although I only ever saw him at cons, I sometimes thought about just ringing him up and seeing if he might like to get a cup of coffee.
