Yeah, I'm aware of this and said as much in a previous comment. I appreciate you giving a more detailed explanation, but wish you hadn't also included a sentence implying that I "think theological thoughts about AI".
As you say, this needs to be investigated more using complexity theory, but my guess is that we won't reach any definitive conclusions due to the difficulty of the problem. (For example we can't even prove the hardness of inverting cryptographic hash functions specifically designed to be secure, so how can we expect to prove the hardness of doing this kind of brain reconstruction?) What we should do in that case isn't clear, but it seems worth taking a chance if the cost of (sufficiently detailed) neuroimaging is low enough. What do you think?
I just thought of a good analogy: if you have a hash of random gibberish you don't need recovered (thermal fluctuations amplified by neurons) combined with the data you want to recover (personality), if the random gibberish is larger than hash you'll probably not be able to recover useful data. That leaves open the question how much random noise gets hashed into result.
