I bet people will wish they had their entire digital footprint and history.
And want it to be known. Good actors will.
I think the pull to prove how you are a unique contributor to the universe will encourage people to want to share it all.
e.g. share and risk reputation.
I think at least it will be valuable to have personal histories that can be used to reproduce a person, digitally spiritually whatever.
They are a component in a bigger digital sandbox / simulation.
