Three Faces of Transhumanism
Transhumanism is, broadly speaking, a philosophical and
technological program that advances the position that technology should be used
to enhance human mental and physical capabilities, both on an individual and
species-wide basis. This is a contentious position. Critics of transhumanism
have argued that it violates the divine order of the
universe, degrades
the human spirit, introduces
unprecedented technological risks, reinforces class inequality,
is
insufficiently diverse, is ignorant of
cultural values and its own past, represents
an unjust colonization of future generations, and is scientifically
untenable.
As a transhumanist fellow traveler, I will say that these
critiques have some merit. It is only fair that a movement with aims somewhere
between an industrial revolution and the creation of a new (and hopefully
superior) sapient species take a lot of flak. But my problem with many of these
critiques, as embodied by a recent scholarly book on transhumanism, is that
they use a strawman version of transhumanism. Transhumanism isn’t just an
ideology developed in a . Now, through the groundbreaking research practice of reading
what transhumanists have to say about themselves and going
to their conferences, I’ve developed a basic taxonomy of the major
factions of transhumanist, Immortalists, Cryonicists, and Uploaders. I’d like
to examine the program and philosophy of these factions individually.
Immortalists believe that the oldest and most important
human problem is death, that death is caused by cellular aging—damage to the
body on a molecular and chemical level—and that therefore reversing aging
through cellular rejuvenation should be a primary research goal. Immortalists
are most closely affiliated with Aubrey de Grey and
the SENS Foundation. From a philosophical and science policy
perspective, I greatly admire the Immortalists. They’ve taken the basic
morality of modern medicine, that death should be prevented by any means
necessary, and extrapolated it to its logical conclusions. If death is not
evil, but simply the final stage to life, then more resources should be
invested in answering the question “What is a good death, and how do we attain
it?” rather than squandered in a fragmentary struggle against individual
diseases. The Immortalists do not have answers to questions like “Would an
immortal species be more just or wise than mortals?” or “How will necessary
change occur when the powerful never leave their positions?” or “If immortality
is a limited resource, how should it be distributed?” Conversely, to argue for
the necessity of death is an much more untenable position.
Cryonicists note the contemporary inadequacy of technology
for undertaking the transhuman program, and focus on the cryopreservation of
nearly-dead people in the present, assuming that they will be resurrected using
future technology. Cryonics, most noteably associated with Max More and Alcor,
are the most programmatically advanced faction. While no organism has yet been
successfully unfrozen, you can sign up for Alcor’s preservation services today.
Cryonicists trouble our notions of life and death, moving from heart cessation,
to brain death, to information-theoretic
death. A successful revival (particularly from LN2) will problem require
Drexlerian nanotechnology to repair cellular damage, and it is an open question
if future beings will want to have a bunch of future-shocked primitives walking
around. In the present, cyronics has caused conflicts
in families, and while the costs associated with preservation are not
astronomical, they are high enough that it is reasonable to question if that
investment would be better made in your descendents or charitable donations.
Uploaders take the position that what is significant about
humans is our capacity for thought, and that the main problem with human
cognition is that the brain is a crappy computer that stops working aft. By
moving cognition from a neural substrate to a semi-conductor substrate, human
can achieve immortality through cognitive backups, intelligence amplification
via Moore’s
Law, and direct experience of a whole digital universe. Uploaders are most strongly affiliated with Ray Kurzweil and the Singularity Institute. Uploaders have what is both the most
mainstream version of transhumanism (robots and digital minds are a commonplace
scifi trope), and what is also the most radical. The Uploader program is based on several
assumptions about the philosophy of mind and computer science that seem
optimistic and partial at best. The first is that the best definition of
identity is computation, rather than being based on any kind of physical or
process continuity. Uploaders would need to prove that the mind running in silico is the same as the biological
original to the satisfaction of skeptics in a way that is more demanding than
the burdens placed on Immortalists and Cryonics. And for a movement heavily
based in computer programming, Uploaders seem very optimistic that attempts to
simulate the mind will not run afoul of limits in both computational
complexity and mathematical
incompleteness, and the long term viability of obsolescing computer
hardware and data formats.
Compared to mainstream conceptions of humanity, all these
transhumanist factions have more commonalities than differences, but the
differences are very real, and should not be ignored or glossed over. In a
future post, I plan to examine transhumanism more holistically as a movement
and ideology, but first, I believe it import to clear up some of the political
distinctions between three very different visions of the future.
