As a thought experiment, this idea may be a little done but I still like the idea that we could be in a Groundhog Day situation and not know it or have been a different person yesterday and woke up in this continuity today. Perhaps if we could conceptualise this as a “veil of ignorance” experiment the world could be a better place, if we genuinely didn’t know who we would wake up as tomorrow but knew that we were going to know that we had changed. Or maybe it would be a tragedy of the commons and we would trash each other’s lives. I’d like to think we wouldn’t, in case we had to come back.
