Will we be able to live in the past as our past self of course with our own custom changes to make life fun?
I think we will need to perfectly simulate a second of a past date and then just let play out.
It's what I am super excited to do post singularity I want to play all kinds of games where I become my self from the past but with customized changes. I can work towards what I want in different scenarios or just mess around with superpowers and I am living in what is effectively the real world because I am living from the starting point of a replica of the past.
I tried posting this in r/singularity and it was deleted for some reason I think I have posted something similar here before but I am really digging for a answer on this.
