The mind uploading stuff seems to be a way to justify being ok with dying, imo, and digging ones head into the sand, pretending that if something talks a bit like you, it is you.
If a friend can very accurately do an impression of me and continues to do so for a week, while wearing makeup to look like me, I have not ‘uploaded’ myself into them. And I still wouldn’t want to die, just because there’s someone who is doing an extremely good impression of myself.
That’s like saying a future version of a tree is doing an impression of a continuation of the previous tree.
I don’t understand how the difference isn’t clear here.
