</div></div></blockquote><br></div>For all practical purposes one can consider the "brain" (as in the biological system) to be the matter which the mind. You can to a large degree (at least IMO) consider the "mind" to be the successive information states that brain goes through. For example you can consider taking a piece of paper and turning it into an origami crane. The paper goes through successive information states each a little different from the one before it. You can kind of consider the "mind" to be the successive forms that the paper (brain) goes through in the process of going from a flat sheet to a folded crane.
<br><br>Cryonics "reversal" or "reanimation" as I like to call it will depend upon the technical capabilities which may be developed in the future. One group of followers prefers to believe that the brain will be restored and the "mind" will be reactivated. (Similar to individuals who recover from a low temperature drowning). Another group of followers prefers the option of simply transferring the information state from the brain to a computer which can perform the identical or highly similar processing functions (this is commonly known as uploading). There at least a third form which I've been thinking about lately where a person may choose to have their "information" recovered (
i.e. memory readout) but require that the essential structure/information which would allow one to run the mind. This is kind of the difference between restoring a computer from a "suspend" state (nanobiological cryonics reanimation), rebooting the computer [on different hardware which can function "like the original" [1]] (uploading) and data restoration (from a hard drive, tape, etc.).
<br><br>To a large degree what will be possible may depend on when one attempts them. I happen to think that the order in which they will be developed will be:<br>1) Biological reanimation (probably leveraged using nanorobots).
<br>2) Information recovery (memory readout).<br>3) Full uploading onto non-wet-brain hardware.<br><br>#2 is probably a prerequisite for #3. Whether (1) or (2 + 3) will be first developed first remains an open question. I tend to lean towards (1) as being possible probably 5-10 years before (2 + 3). Also, IMO, I would expect that humanity would have to suffer a severe developmental setback (
e.g. an "Armageddon" type event) for these not to be available by the 2050-2060 time frame. If we pushed a little harder on them we could have them in the 2020-2030 time frame.<br><br>Some people might want to ask why you would ever want #2 and not #3. My answer would be that most people do not like to function in environments in which they are not comfortable. Most people transitioning from the slow run up to the singularity to the stage where it becomes painfully unavoidable may consciously choose to not want to have to live in that "crazy" world. They might however want to leave humanity their memorys, insights, stories, etc. Right now one only has available very crude tools for sharing oneself (teaching children or students, establishing foundations, created entities (companies, art, estates, etc.), writing autobiographies, ...). Choosing #2 without #3 allows you to give humanity literally "all of oneself" without having the problem of getting up sometime in 20, 30 or 40 years and having to upload 100, 102, 104, 108, 116, 132, etc. terabytes of information *each* successive morning just to keep up with everything that changed in the world while you were sleeping.
