Six wild ideas for perpetuating your mind
The hardest part of mind uploading was never going to be the scanning or the compute. We already know how to map neurons, roughly, and Moore's law keeps doing its thing. The part that gives me pause is the continuity. If you freeze someone, or copy their connectome into a simulation, the person who wakes up on the other side might be a perfectly faithful reconstruction, with all the same memories and quirks. But is that you, or is it someone who thinks they're you?
That distinction matters more than the tech. Most of these wild ideas lean on the assumption that information is identity, that if you can copy the pattern, you've copied the person. I'm not convinced. A scan of your brain is a map, and a map can be copied without moving the territory. The original is still there, and the copy is still a copy, no matter how many terabytes it takes to store it.
What I'd want to know next is how any of these proposals deal with the experience of dying, because that's the moment people are actually trying to cheat. If the answer is "well, you won't notice the difference," then you're printing a biography that happens to be written in neural language. The mind itself is left behind.
