Ray -

I'd be curious which parts you found most interesting or of value.
Feel free to quote from it if you wish.

I didn't want to reply before reading your book. So, I've been occupied
with reading "The Age of Spiritual Machines" in my spare time this past
week or so.  I have many things I could say (it is well written and
convincing for one). But I will focus on what I see as the most
important issue you raise.

First, I agree in general with the premise related to exponential growth
of computing and many of the implications. That isn't due to your book,
but your book definitely convinces me more of the truth of this. I don't
believe I had been aware of your "Age of Intelligent Machines" book
before. http://www.kurzweiltech.com/machines.htm

In 1985, I had just graduated from Princeton (undergraduate), working
with George Miller (Marvin Minsky's advisor in the Snarc days) doing
cognitive science related to AI. I wanted to build an AI that could
preserve homeostasis in a space habitat.

Afterwards I went to live in Pittsburgh for a year and basically hung
around CMU at the Robotics Institute. I was a visitor in Hans Moravec's
Mobile Robot Lab at CMU/RI as he was writing "Mind Children" (proposing
replacement -- downloading was a minor option then). I also was visiting
with Red Whittaker's Field Robotics Laboratory (Red is a proponent of
person in the loop -- robotics as augmenting human abilities). Of the
two visions, I found Red Whittaker's more desirable (MOSH to the end I
guess). I remember when one of the people working with Hans explained
how we would be able to download our minds into robots and explore the
universe. My reaction was mostly that technically I believed this was
possible (in some way) but it was quite possible things would go wrong
(with either transference or a generation of competitive machines).

While your "The Age of Spiritual Machines" and Moravec's "Robot" both
serve to convince me more strongly of the premise, I still retain the
reaction that it is likely things will not work out so well for humanity
as one might hope, without explicit action to construct alternatives.
Some of this is based on my studies in Ecology and Evolution. I pursued
a PhD but only got an MA from SUNY Stony Brook -- the program wasn't
ready for ALife studies or ecological simulations as study topics there
in 1990.

In my opinion, your analysis of the evolutionary dynamics of a world
wide web of downloaded humans is flawed because it ignores fundamental
aspects of ecology and evolution. Specifically, here are two issues
about your conclusion:
a) it assumes humans in a different environment will still act human
with classical human motivations (as opposed to dissolve into an
unrecognizable set of bits or simply locking in a pleasure loop) because
to a large extent environment elicits behavior, and
b) it ignores evolution and its implications in the digital realm
(especially the enhanced pace of evolution in such a network and the
implications for survival).
Of these, the most important is (b).

Evolution is a powerful process. Humans have evolved to fit a niche in
the world -- given a certain environment which includes a 3D reality and
various other organisms (including humans). Humans have an immune
systems (both mental and physical) capable of dealing with common
intellectual and organismal pathogenic threats in their environment.
There is no easy way to translate this to success in a digital
environment, because the digital environment will imply different
rewards and punishments for various behavior, and evolve predators and
parasites which these immune systems have never been exposed to before.
Human style intelligence is valuable in a human context for many reasons
-- but sophisticated intelligence is not necessarily a key survival
feature in other niches (say, smaller ones the size of roaches, hydra or
bacteria). In short, the human way of thinking will be inadequate for
survival in the digital realm. Even augmented minds that are connected
to the network will face these threats and likely be unable to survive
them. You discuss the importance of anti-viral precautions in your book,
but I think you are rosily optimistic about this particular aspect.

At best, one might in the short term construct digital environments for
digital humans to live in, and defend these environments.  However, both
digitized human minds and immensely larger digitized human worlds will
be huge compared to the smallest amount of code that can be self
replicating.  These digital "bacteria" will consume these digital human
minds and worlds because the human minds and worlds will be constructed,
not evolved. Human minds will be at a competitive disadvantage with
smaller, quicker replicating code.  Nor will there be any likelihood of
a meaningful merger of human mind with these evolved and continually
evolving patterns.

I could endlessly elaborate on this theme, but in short -- I find it
highly unlikely that any mind designed to work well in meatspace will be
optimal for cyberspace. It will be overwhelmed and quickly passed by in
an evolutionary sense (and consumed for space and runtime).  It is
likely this will happen within years of digitization (but possibly
minutes or hours or seconds).  As an example experiment, create large
programs (>10K) in Ray's Tierra and see how long they last!
http://www.hip.atr.co.jp/~ray/tierra/tierra.html

Our best human attempts at designing digital carriers (even using
evolutionary algorithms) will fail because of the inherent
uncompetetiveness of clunky meatspace brain designs optimized for one
environment and finding themselves in the digital realm. For a rough
analog, consider how there is an upper limit of size to active creatures
in 3D meatspace for a certain ecology.  While something might survive
somehow derived from pieces of a digitized person, it will not resemble
that person to any significant degree.  This network will be an alien
environment and the creatures that live in it will be an alien life
form.  One might be able to negotiate with some of them at some point in
their evolution citing the commonality of evolved intelligence as a bond
-- but humanity may have ceased to exist by then.

In short, I agree with the exponential theme in your book and the growth
of a smart network. We differ as to the implication of this. I think
people (augmented or not) will be unable to survive in that digital
world for any significant time period. Further, digital creatures
inhabiting this network may be at odds or indifferent to human survival,
yet human civilization will likely develop in such a way that it is
dependent on this network.  The best one can hope for in the digital
realm is "mind children" with little or no connection to the parents --
but the link will be as tenuous as a person's relation to a well
cultivated strain of Brewer's yeast, since the most competetive early
digital organisms will be tiny.

Once you start working from that premise -- the impossibility of people
surviving in the digital world of 2050, then your book becomes a call to
action. I don't think it is possible to stop this process for all the
reasons you mention. It is my goal to create a technological alternative
to this failure scenario. That alternative is macroscopic
self-replicating (space) habitats.
http://oscomak.net/
However, they are no panacea. Occupants of such habitats will have to
continually fight the self-replicating and self-extending network jungle
for materials, space, and power. (Sounds like the making of a sci-fi
thriller...) And they may well fail against the overwhelming odds of an
expanding digital network without conscience or morality. Just look at
Saberhagen's Beserker series http://www.berserker.com/ or the Terminator
movies.

It will be difficult for you to change your opinion on this because you
have been heavily rewarded for riding the digital wave. You were making
money building reading machines before I bought my first computer -- a
Kim-I.  But, I think someday the contradiction may become apparent of
thinking the road to spiritual enlightenment can come from material
competition (a point in your book which deserves much further
elaboration). To the extent material competition drives the development
of the digital realm the survival of humanity is in doubt.

Still, you are a bright guy. If you study ecology and evolution in more
detail, I think you may change your conclusion, or at least admit the
significant probability of a bad outcome, and that we should plan
accordingly.

If you do change your opinion in the future, and wish to fund work
related to helping ensure humanity survives the birth of the digital
realm, please remember me.

MOSH to the end I guess!
