Maybe you’re better than me, I tend to think I do a lot of stuff that my remembering self would not be as happy about as my living self is. I could see something like this helping me get a better balance between the remembered and lived self.
Plus, imagine if you could record and play back experiences. Like playing with a child who later passed away.
Or sharing your feelings of being hurt with your oppressor, and vice versa so you can really feel what it’s like to be each other. Would war even be conceivable in such a world?
