It may not be you staying alive, or maybe so. No real telling if it successfully done. But it could be much more comforting for them. If we could transfer our human essence of our memories, personality, the totality of life's development in us to other people, in general it would be so interesting but starting small here with a death of loved one scenerio.
Would you want your conciousness copy and pasted into another's body? Maybe someone who otherwise would off themselves and hate their current lives. It is a quite disturbing situation for some I realize.
Honestly I probably would consider this, in that state of needing them there to talk to so much. A robotic version wouldn't ever cut it but at least a human could. Fuck moving on and finding someone new. Now the surrogate loved one I guess you could say would still be there mentally. They'd just feel drained, confused as they are rediscovering their new selves for a bit.
