(Art) Imagining a near-term superintelligence [Cont'd]

You may notice that I used both the "big five" personality factors and MBTI factors interchangeably though they are different in significant ways I won't go into here.

Below is a summary of the last post which should be easier to survey. Of course the whole model can be reduced as lean as appeared in the first post.

Interesting "planning" tool for next fifty years

Although I agree with Nick Bostrom that we need to space out our probability estimates far when forecasting events like the singularity this planning tool seems like a reasonable approximation for the time at which various events will occur (let's just call "omnipotence" something like a Jupiter Brain or Matriosha Brain).

http://danila.spb.ru/papers/planning/future.html

Teach your children well, and ideally teach them to program and an in-depth science (e.g. "Biohacking"/DIYbio) or mathematical subject. Programming = many rewarding opportunities, options and personal empowerment.

I've been told the Russian Transhumanist Movement is focusing on optimization of research and development by working with industry on advancing technologies ready to be integrated. Here is a summary analysis of the Russian state of tech interest:

Eventual Cloning Tech and Lifestyle Improvements

The idea of advanced adult cloning (depending on advanced nanotech and supercomputing as well as greater control of biology) understandably leaves many people feeling ambivalent if not hostile based on gut reactions and negative hypothetical scenarios. However, in time it should be welcomed for its life-saving and life-enhancing qualities. As previously mentioned, at the subatomic level at least there seems little if any continuity of physical substrate over time, especially across discontinuities of consciousness as occur during sleep (or even, arguably, shifts of attention). Therefore, advanced cloning should be considered in many ways as "continuous" with identity as a single body existing through time, at least at and near the point of copying and highly similar in relevant ways if not technically identical over longer timespans.

The foremost benefit of the ability to produce cloned copies of a person would be to serve as a fall-back in case of lethal accidents. Yet mature utilization of the technology also would reward more rational risk-taking in careers and life and reduce the damage incurred from poor decisions or risky efforts that do not succeed. Indeed, the equivalent of suicide missions could be lived out as merely strange days in a much longer lifespan with a broader scope of experience (both interpersonally from the view of others and subjectively either as gaps of experience or experiential endings minus the existential finality of historically normal death). Beyond the individual perspective, families and friends could retain loved ones over longer lifespans.

I once spoke with Eliezer Yudkowsky on the death of his younger brother Yehuda - an unmistakeably brilliant materials science student, active Republican college radio pundit and Jewish cultural leader - to what appeared to be suicide. He found it annoying that his religious family at the time were consoling one another by stating he was "in a better place." I mentioned that at least on some interpretations of physics a wide array of possibilities were realized and that Yehuda would still be alive in many of them. Eliezer replied that although that might provide some consolation in the abstract it still doesn't change the lived experience of continuing through life without his brother.

Any overpopulation issues could be worked around through policies limiting the number of clones via something like a carbon tax differentiated by levels of pollution in energy extraction (not the apparently ineffective cap and trade approach), or analoguously the waste or benefit derived from income sources (e.g. gambling and prostitution versus software development or college instruction). Preferably, the policies would be ones that did not disincentivize reviving deceased people but placed productivity demands (via rational and limited taxation, for example) on the number of coexisting clones one could produce of oneself (in the case of geniuses or popular people, others might foot the bill). Drawing again on the analogy of renewable energy incentives, we might even pay people for the excess productivity of their clone groups beyond given thresholds.

In short, I see advanced cloning as offering a potential bridge between rational interests for the self, society, and communities of affiliation. If we manage to avoid destroying ourselves first, I think such cloning will become an integral part of the future of humanity, even as we also pursue computer uploading, computer-brain interfaces and other technological advancements that will continue to transform the nature of human beings.

Cloning and Self-Enhancement in Relation to Life Extension

I used to be opposed to the idea of cloning oneself as a means of life extension for three reasons: 1) early cloning work resulted in sickly animals, 2) a newborn clone will have different life experiences that shape its biology and mind, and 3) I held a naive materialist view of the locus of a subject of experience and action or self-same mind.

I have moved beyond my third objection to view information processed in a manner that is relevantly the same to be an identical mind. Now, if cloning techniques were better, say, even allowing healthy identical copies of adults to be produced (perhaps with advanced nanotech and supercomputing) I would consider that fully adequate for life extension. Moreover, it easily could encourage venturesome risk-taking rather than discourage it among people who find appealing the incentive of a long and youthful lifespan.

At some point, I suspect that such approaches to life extension will be adopted in part because it offers the best of both investment strategies: high risk and novelty seeking / high reward potential and long duration of learning and expertise cultivation through risk aversion / likelier reward potential even if comparative returns are modest. Additionally, more of the same person could be applied to a given problem or challenge (e.g. several clones of the same nobel prize winning physicist could compete and collaborate with one another and other as well as clones of other notable or highly capable physicists to save the planet from the latest existential risk).

Notice I mentioned physicists. On a morning news show with a section on radical life extension I saw an interviewer ask Aubrey de Grey if it really was worth living to watch a million episodes of reality television (to which Aubrey replied something like he wouldn't want to watch a million microseconds of reality television but you can't do anything when dead). Although I see nothing wrong with enjoying reality television we should hope to achieve a bit more with our resources; for example, reaching the stars to seed the galaxy with life and averting extinction in the near future.

In developed nations the tested intelligence of the general population has risen slowly based on a more cognitively demanding environment. At the upper end of the spectrum there also are social filters that encourage some traits to an eccentric extent (e.g. the higher rates of Aspergers Syndrome in Silicon Valley). However, the very word "eugenics" is tainted with the murderous and sadistic regime of the Nazis and any explicit program of genetic enhancement through selective breeding might risk promoting sociopathic and psychopathic tendencies along with intelligence.

One genetic enhancement strategy that doesn't risk oppressive social regimes would be voluntary self-enhancement through the use of early childhood education, nootropic drugs and eventually more dramatically effective forms of neural enhancement and nanorobotically achieved genetic engineering within the self-same person. Ultimately, uploading onto another computational format could enable much more radical enhancement. Let's hope that the leaders, legislators and judges of today and tomorrow have the wisdom and foresight to provide both access to such technology (lest the users become outlaws) and regulation for safety (lest unforeseen glitches in cognitive tech seriously harm the users or those who they interact with while under the influence).

Nano is the path to clean energy

The most crucial developments leading the way to clean energy will be technological rather than political, though some political will can help a great deal. The main reason: the economics, which hold sway both for governments that want more power and political groups that want smaller governments.

Initial Synthesis of Ideas

I should start this blog by articulating what I believe to be the most pressing issues for myself and people relevantly like me (e.g. non-AGI experts) to follow and work on.

I am working to focus more on life extension issues and less on partisan politics. However, the politics of the external environment can matter a great deal to one’s prospects for extending biological lifespan and internal experience, as well as the lifespans of those one knows and cares for in the world. I will try to balance surveys of the environment with projections for biological life extension. The emergence of superintelligent artificial general intelligence might considerably alter the relevant dynamics but I will focus on more knowable futures including those in which superintelligent AGI takes a very cautious, hands-off initial approach to influencing the world.

Ultimately, I think that the primary focus in life extension should be on survivability for humans (in some form) and intelligent, sentient beings, including AGI. Although there are important considerations regarding the meaning and nature of life and death I believe that life extension and health maintenance – in biological as well as robustly “uploaded” formats – is the most important agenda following overall survival of intelligent beings and civilization, characterized by Nick Bostrom as “existential risks” or risks of extinction as well as large scale disasters. Both callous abstraction from the suffering of particular individuals and blind or unscrupulous protection of people closest to ones’ own heart (perhaps including even oneself in some cases) seem to be extremes to avoid in contemplating and striving to reduce existential risks.

Jamais Cascio is an excellent source for conceptual frameworks regarding civilization survival and sustainable culture. Although current proposals involve many risky unknowns I agree with Cascio that at this point it seems that even drastic reductions of greenhouse gas emissions will not prevent significant climate change and “geoengineering” projects will be needed to help slow and control the process. Although I am intrigued by newer, less brittle economic models discussed by Cascio, I’m inclined to think the next decade will be shaped most by the familiar combination of party Liberalism and Corporatism, and the latter force will only adopt green tech as it becomes cost competitive with older technology. I think “bright green” market-oriented, consumer-driven technology will need to be the basis for much progress though private initiatives and public incentives will be needed to accelerate the process.

Cascio may be right that eventually, if we manage to avoid dystopian nightmares, we may realize “resilience economics” leading to islands of “just-in-time socialism” and eventually even a “basic income guarantee” society as robots take over most jobs. Between now and then, it would seem well advised to make oneself as independently valuable as possible, and there is hardly a better industry for that than life extension as it provides an appealing benefit to consumers as well as to society at large (given that members can work longer at higher capacity).
A less impersonal life extension agenda is striving to realize a “longevity escape velocity” a process in which one lives long enough to benefit from the technological advances that enable escaping death from what currently are considered “natural causes.”

Here is part of an E-mail I received from Micheal Rae in response to an inquiry concerning the progress of biogerontology and the role of nanotechnology in achieving radically longer lives:

" Certainly, it's likely that in the short term, we'll be using some of what we might call "conventional" nanotech as part of tissue engineering, in bioMEMs, immunoisolated tissue/organ constructs, etc. However, these certainly won't be *indispensible* or even central elements of the *immediate* goal of "longevity escape velocity" (LEV). Rather, more advanced, 'blue sky' "Drexlerian" nano (hard-core molecular manufacturing devices/nanobots), will become necessary at some time in the future, as part of that ultimate, comprehensive panel of rejuvenation treatments (whereas the first generation will be entirely composed of foreseeable biotechnology). For instance, one can see that a very strong ("Drexlerian") form of nanotechnology, which could maintain a mutliply-redundant copy of the genome, compare it to the genes in a given cell, and directly repair errors (having thus the crucial ability to look in on a given cell's genome from without, instead of being limited to comparing one DNA strand to the other as our endogenous repair mechanims are), might be expected to be a powerful and effective approach.

More on Dr. de Grey's speculation on the role of molecular manufacturing in future age-reversing biotech here:

I intend to start learning more about Dr. Grey’s work and how I can support it.
