Recently, there was some confusion by biologist P.Z. Myers regarding the Whole Brain Emulation Roadmap report of Anders Sandberg and Nick Bostrom at the Future of Humanity Institute.
The confusion arose when Prof. Myers made incorrect assumptions about the 130-page roadmap from reading a 2-page blog post by Chris Hallquist. Hallquist wrote:
The version of the uploading idea: take a preserved dead brain, slice it into very thin slices, scan the slices, and build a computer simulation of the entire brain.
If this process manages to give you a sufficiently accurate simulation
Prof. Myers objected vociferously, writing, “It won’t. It can’t.”, subsequently launching into a reasonable attack against the notion of scanning a living human brain at nanoscale resolution with current fixation technology. The confusion is that Prof. Myers is criticizing a highly specific idea, the notion of exhaustively simulating every axon and dendrite in a live brain, as if that were the only proposal or even the central proposal forwarded by Sandberg and Bostrom. In fact, on page 13 …
