our memories of our past self would get grainier and grainier

The computer model of memory would lead to that. However, the radio model of memory would allow continuation. It doesn't work for modern electronics where there are no user maintainable components inside, but the old tube radios could be resuscitated forever by replacing worn out tubes.

I'm a bit curious about the radio model. Where is the seat of consciousness?

If I hit my thumb with a hammer, I am aware of the injury, and the pain has a profoung effect on my behavior. But I can put aside pain if my survival depends on it. I can "objectify" my thumb and see it as something that is part of me but not mu central self.

I'm curious how the radio brain accounts for mind altering drugs. Why can't our real self see our addled brain as a disfunctional component that needs to be put aside for a while until it recovers?

And dried-out capacitors...... which at tricker than tubes when the originals were hand-rolled.
