I am interested in exploring the idea of the development of consciousness uploading/brain scanning technologies. Exploring the alpha stages of the technologies. So, you might get a partial consciousness or brain scan and the gaps in the scan might be filled in with guesses or chatbot-like technology that might try to simulate that part of a human consciousness.
In my world I am proposing a brain scanning technology that might cost as much as a house, or peoples entire life savings. That could offer a sort of immortality by digitizing your consciousness shortly after your death.
But the technology creates an incomplete copy of you and fills in the blanks.
So, maybe your favorite color is red before being scanned, but the scan misses that bit of information and so it sets your favorite color to blue instead.
Maybe you're not good at math, but the scan doesn't do well in that part of your brain, so it adds in a generic math plugin to your digital consciousness.
My thinking is that even if people know the scan is a bad copy of your consciousness they would still choose the scan when the only other option is death, and that when death is the alternative people would pay their entire life savings.
