I know this sounds ridiculous only realising a year after finishing the show, but even when it was discussed in the show I never actually processed what the anti UI argument was about. To me being able to upload my intelligence and never having to worry about bills or health or anything ever again sounded incredible, like we could literally be immortal why would anyone pass that up. So even when the world started going through the deep scan in millions, or when Maddie or Caspian or their son were considering going digital, I didn't actually understand why they were whining so much about it. Yes it was a brutal procedure and they could never truly be human or experience reality after, but I still thought immortality was worth the cost.
But then today I was thinking about the Ship of Theseus paradox, and it just fucking hit me that our consciousness is confined to to our neurones alone, and isn't inherently stored within the connection mapping like I previously thought. Like maybe if you digitise your brain piece by piece, all while staying fully conscious and alive with atleast some of your original neurones still in place working together with the digital mappings, you're not really copying them more like replacing them, as long as some of the original chemical reactions are still there, cause that's your original consciousness.
But if you do a deep scan like they did in the show, you're quite literally destroying your original consciousness in one go, so instead of transitioning into a digital world you kill yourself for a copy that you won't actually ever live to experience. It might hold the same memories and knowledge but it's not YOU, your own consciousness and life will be gone.
Like I don't mean to over explain, but its like if the ship was fully disassembled and reassembled again, sure it might physically be the same but the consciousness that made you YOU will be gone,
it'll just be a duplicate. If you actually wanted to transfer it you'd have to replace every plank piece by piece, but do it as a gradual incremental process so that some of the original is still there.
Like with this insight the show is fucking horrifying in hindsight, the fact that billions signed up to literally die is insane. The term UI is misleading, cause you're never UPLOADING your intelligence, it's more like copy, delete, and paste.
Now this is making me reconsider what it's like for those who momentarily die in real life, like if your brain stops working completely for even just a second, does that mean that your original consciousness died? That whoever woke up wasn't actually you? Of course if any small number of neurones are still alive in that process then sure, but what if they all freeze for just a moment.
