I don't know when it will be possible. It all depends on how long it takes to develop nanotechnology, at that point everything we can presently imagine will be either impossible or easy, nothing will be difficult. Coincidentally, this is exactly the same point at which the revival of cryonics patients becomes possible, there is no way you could repair massive brain damage at the cellular level without it. >We have very little knowledge about how the brain works That's true, but we don't need to know how the brain works to upload it, just copy from nature,- if neuron A, B and D but NOT neuron C fires, then neuron E will fire. Do that sort of thing for several trillion neurons. We don't need to understand why this complex mess works because we have an existence proof that it does indeed work and you are the proof. It is not necessary to understand a book in order to type it. >and it would have to be completely mapped down to atomic >resolution I doubt if you would even need molecular resolution, much less atomic resolution, but even if you did nanotechnology can provide that. >with the knowledge of how all of the chemistry responsible >for thought Chemistry is not responsible for thought, information is. A computer made of integrated circuits or transistors or vacuum tubes or mechanical gears or hydraulics or protein all produce the same outcome. How the signals are transmitted internally is only a matter of speed , reliability, and engineering connivance. >the advantage to being in physical form is that you are >mobile and atonymous of any computer network. A upload would not be stationary, although his brain might be, he might not know or care where his brain was, he'd only be interested in where his senses were. You don't feel static or imprisoned even though you are floating in fluid in the dark inside a container made of bone, your skull. You have senses, so would an upload. I doubt that any cryonics patients will by revived with physical bodies, the powers that be would not want primitive, penniless, people like us wasting resources. It will be cheaper and safer for them to upload us, we'll be charity cases so who can blame them, besides, if you can't tell the difference why would you care?
