And now for some news from the world of
Technology Beyond Good Sense.
According to George Dvorsky at Futurism, scientists at MIT and 21st
Century Medicine have developed a new mammalian brain preservation technique
that makes it possible to save the information stored within the structure of
the brain—memories, for example, or sensory data—after the death of brain
tissue. The technique, called Aldehyde-Stabilized Cryopreservation (ASC), has
so far been tested on rabbits and pigs, and is promising enough to have earned
its developers a research grant which would help them take the first steps
toward long-term human brain biostasis.
Though the scientists hasten to add that
they are nowhere near that point now, but results of their studies have been
independently verified and published in the scientific journal Cryobiology. One of the scientists,
Robert McIntyre of MIT, has gone so far as to establish a private company with
the stated goal of developing a technology
to
preserve your brain well enough to keep all its memories intact: from that
great chapter of your favorite book to the feeling of cold winter air, baking
an apple pie, or having dinner with your friends and family. We believe that
within the current century it will be feasible to digitize this information and
use it to recreate your consciousness.
Am I the only one who finds this a little
creepy? Especially when you learn the ASC technique doesn’t actually preserve
the brain itself, but turns the thing into a kind of “plasticized object,” an
object, we can only hope, retains the relevant information contained in the
grey matter it, um, replaces during the cryogenic process.
Dvorsky puts it this way:
For
those of you thinking this is a path towards immortality, you may be in for a
profound disappointment. Technical hurdles aside, the ASC approach doesn’t
guarantee a continuity of consciousness. As mentioned, [euthanasia to preserve
the brain before death by terminal illness} is a form of destructive
preservation, where biological matter is basically transmutated into a
temporary storage device. While your memories and personality stand a chance of
revival, your seat of consciousness will likely be obliterated for all time.
Brain preservation in this manner is thus a form of suicide, but with knowledge
that a digital “copy” of you may live to see another day.
Okay, wow. You can replicate your
personality and memories, but not your actual consciousness? And where,
exactly, does that consciousness reside? Certainly not in the brain tissue, if
I remember my Sunday school lessons correctly. (And I think Buddha, Muhammed, the
Taoists, priests and shamans of multiple faiths and even some wiccans would
agree with those lessons.) And what good is retaining your memories and
personality, if your consciousness is somewhere else?
Of course, plot bunnies are hopping all over
my consciousness at this point. The simplest and most obvious use of this
technology would be military (or should I say military intelligence). Your spy
dies in the field? No problem! Just “download” his brain to get that vital
information! Combine this tech with cloning and you’ve got any number of copies
of James Bond—all dispensable.
A frightening idea. And, now one that is
ultimately possible.
Cheers, Donna

Holy cow! This makes the "virtual vacation memory implant" in Total Recall now seem completely within reach. Actually, it makes the "replacement personality" in the same movie also within the realms of possibility.
ReplyDeleteI agree, the implications are totally frightening...but also great stuff for plot ideas!
