Randomly diving in the enormous archives of my Chaos Node, I think I found the first entry that outlined my belief in the Coming Change and the parallel to the arrival of the current mind. It was more than a year before the longer series in 2005. And it was in part based on an even older entry, but one that only contains the seeds of the idea, not yet sprouted. (There is a link to that entry too.)

A super future, if any (Idus Martiæ, 2004).
