From the age of 20, we losea day. But don’t worry , we mostly lose neurons that have not found their use, they have not been solicited to get involved in any information processing. This triggers a programme to self-destruction . In other words, several tens of thousands of our neurons kill themselves every day. Other neurons die because of exhaustion or infection.
So, given that we don’t know how much storage is required, that we cannot hope to find enough time and resources to entirely map the 3D structure of a whole human brain, that we would need to cut you into zillions of minuscule cubes and slices, and that it is essentially impossible to decide when to undertake the transfer, I hope that you are now convinced that it is probably not going to be possible for a good while, if ever.
To know which types of connection apply between two neurons, we need to apply molecular techniques and genetic tests. This means again fixating and cutting the tissue in thin slices. It also often involves dying techniques, and the cutting needs to be compatible with those. But this is not necessarily compatible with the cutting needed to reconstruct the 3D structure.
If this hypothesis is correct, however, I must object. Imagining that all the impossible things listed above were one day resolved and your brain could literally be “copied” into a computer – allowing a complete simulation of the functioning of your brain – at the moment you decide to transfer, Richard Dixon would have ceased to exist. The mind image transferred to the computer would therefore not be any more alive than the computer hosting it.
Without interaction with the world, however subtle and unconscious, how could the mind function even for a minute? And how could it evolve and change? If the mind, artificial or not, has no input or output, then it is devoid of life, just like a dead brain.
