Starting with this reply to "You were born too soon":
> depending on when exactly we achieve this, this could be the best time to be born ever, because it will be the absolute earliest anybody will have achieved immortality. Someone born within 20 years of this moment could one day be the oldest human, sentient, or even living being in the Universe.
The comments are currently split between arguing and agreeing with this. So far, no mention of cryonics. One post presents a possibly interesting technical argument that our current knowledge/technology is centuries away from mind uploading/whole-brain emulation.
(Also posted to The Singularity in the Zeitgeist, but that thread seems to have been mostly forgotten.)
Possibly relevant: I am my connectome It's already possible to model brains on the neuronal level -- to compute a graph of which neurons are connected to which others. The problem is scale: we've already completed C. elegans, we're still a few years away from a mouse connectome, and who knows about the human connectome.
Microscope resolution isn't the problem. The problem is the computing power required to get from tiny 3d cubes of microscopic images, to a model graph of where the neurons are -- it's an expensive image recognition problem.
That is about as true as "a city is its street map." A street map may uniquely correspond to a real city, but it's still a type error, and there is the strong possibility that significant information is not contained in what got put into the map.
