The upload thread talks about the difficulties in making an upload of a single specific adult human, which would have the acquired memories and skills from the biological human reproduced exactly. (Admittedly, “an upload of John von Neumann”, taken literally, is exactly this.) A neuromorphic AI that skips the problem of engineering a general intelligence by copying the general structure of the human brain and running it in emulation doesn’t need to be based on any specific person, though, just a general really very good understanding of the human brain, and it only needs to be built to the level of a baby with the capability to learn in place, instead of somehow having memories from a biological human transferred to it. The biggest showstopper for practical brain preservation seems to be preserving, retrieving and interpreting stored memories, so this approach seems quite a bit more viable. You could still have your von Neumann army, you’d just have to raise the first one yourself and then start making copies of him.
