And yes that is a singularity however in physics, unlike pure mathematics, when you run into a singularity what that is really telling you is that there is some unknown physics going on that you don't understand, or don't understand well enough. Everybody knows something is wrong but nobody knows what. * *By the way when people, like me, say that because of AI we're heading towards a Singularity they are using poetic license, things in general and society in particular won't really be changing infinitely fast, just faster than the human meat brain can comprehend. * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> e4b > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
