A couple of quibbles with the article:<p>&gt;While progress is swift, no one has any realistic estimate of how long it will take to arrive at brain-size connectomes. (My wild guess: centuries.)<p>It&#x27;s not so hard to estimate. Just extrapolate progress on scanning, computing etc. About 2050 plus or minus a couple of decades. We had a 20um scan in 2013 and you&#x27;d probably want to get that down to 20nm for a connectome so if you assume resolution doubling every couple of years that would be about 2035.<p>(2013 scan: <a href="http:&#x2F;&#x2F;io9.com&#x2F;see-the-first-ultra-high-resolution-3d-scan-of-the-ent-514395280" rel="nofollow">http:&#x2F;&#x2F;io9.com&#x2F;see-the-first-ultra-high-resolution-3d-scan-o...</a><p>Images showing neural connections: <a href="http:&#x2F;&#x2F;book.bionumbers.org&#x2F;how-big-is-a-synapse&#x2F;" rel="nofollow">http:&#x2F;&#x2F;book.bionumbers.org&#x2F;how-big-is-a-synapse&#x2F;</a>)<p>Of course as the article points out a connectome misses a lot of chemical detail.<p>&gt;It will almost certainly be a very long time before we can hope to preserve a brain in sufficient detail and for sufficient time that some civilization much farther in the future, perhaps thousands or even millions of years from now, might have the technological capacity to “upload” and recreate that individual’s mind.<p>Or quite possibly we can do it just now for $30k or so by sticking the body in liquid nitrogen.
