… this book is a bit nuts. The story Lovelock is telling here falls within the realm of speculation, not prediction, which he acknowledges with a generous peppering of ‘maybe’ and ‘perhaps’, as well as some winking flights of fancy (‘No such assumption can be made about the cyborgs of the Novacene But what would they look like? Anything is possible, but I see them, entirely speculatively, as spheres’). In this story, the Novacene is the next stage in the cosmos awakening to consciousness, and in our current age of climate catastrophe it is not individuals, or communities, or even human civilisation that must be saved, it is the possibility of this awakening.
I'll stick with Arthur Eddington: The idea of a universal mind or Logos would be, I think, a fairly plausible inference from the present state of scientific theory
