Thanks to Charlie Stross for pointing out Lena, an short story by qntm written in the format of excerpt from a version of Wikipedia hailing from a distinctly nightmarish timeline:
This article is about the standard test brain image. For the original human, see Miguel Acevedo.
MMAcevedo (Mnemonic Map/Acevedo), also known as Miguel, is the earliest executable image of a human brain. It is a snapshot of the living brain of neurology graduate Miguel Álvarez Acevedo (2010–2073), taken by researchers at the Uplift Laboratory at the University of New Mexico on August 1, 2031. Though it was not the first successful snapshot taken of the living state of a human brain, it was the first to be captured with sufficient fidelity that it could be run in simulation on computer hardware without succumbing to cascading errors and rapidly crashing. [...]
If you find yourself thinking that sounds neat, be sure to follow the link and read the remainder of the entry.
I think probably enthusiasts for mind uploading are wildly underestimating the complexity of capturing a snapshot of a mind, let alone the resources required to do something useful1 with all that data afterwards. Then again, a few decades from now who can say how much bandwidth and processing power it'll be feasible2 to throw at the task?
Chilling stuff...
