@chu This is why I wrote '470'. I needed, even for myself, to imagine it as a story, in concrete details rather than abstract probabilities. Even me, and I know the science well. But I realised I wasn't living my day to day life "as if" what I knew to be true was true, and not because of any disputing facts, but because of a failure to imagine. Novelists, artists, storytellers have a big role we need to play.
