Homo deus

Power Valued Over Truth

Dear Ed and All,

“We are the ones that create human nature by inculcating cooperation and care over selfishness and power.”

The view you express, Ed, contesting Harari’s claim in Homo deus, seems to edge up closely to the “pre-modern” standard social science of model of human nature, i.e., that it is almost solely a product of culture, with no or minimal influence of naturally selected genes and very fancy naturally selected epigenetic mechanisms for gene regulation. It is the idea that we pretty much are born, mentally, a blank slate. That is demonstrably wrong. There is a deep and mighty pan-cultural, species-typical human nature that impacts all our intrapsychic life and behavior. It is designed only to be impacted in very specific and limited biologically fitness-enhancing ways by local cultural influences. Harari is correct, at least in the sense that our basic nature is only contingently to value truth, that is, only to the extent that it increases our power to generate greater lifetime inclusive fitness.

Yet, and here is where you and I can find, IMO, great and expansive common ground, natural selection in our species created a mind designed to compete in complex multi-partner, multi-currency socioeconomic bargaining, and thus for status (i.e., power), with great acumen, during an ongoing intraspecific arms race with other humans, including close social partners, over the last several hundred thousand years. Importantly, non-trivial metacognition and mentalization (theory of mind) capacities evolved as part of our package of competitive cognitive capacities; these can be used to evaluate, predict, and manipulate others, and to observe and study ourselves. Imaginative capacities and an ability to believe deeply in both fantasy and evidence also evolved to allow us to cohabit “adaptively subjective dreamworlds” (ASD) that hold human groups together. For example, one example of a written down, very dear and pretty darn auspicious ASD is the US Constitution.

Natural selection has zero foresight. This is the only reason we have any chance of beginning to alter how our minds operate. Down the road, once some leaders develop the capacity to make good decisions about how to genetically modify ourselves to be more compassionate and sustainable, probably with the help of evolutionary psychology, a massive program of intentional genetic evolution may be what’s really necessary to get us through our current very dangerous technological adolescence.

Robust, transparent (nonconscious), sly and clever neurological regulatory mechanisms assuredly have evolved to more or less (denoting very slight individual variation in brain development) lock us into making effective and efficient (i.e., powerful) use of our outstanding cognitive abilities to maximize lifetime gene propagation, whether we know this is what we are up to or not.

Yet, this same program of natural selection, epiphenomenally, gave all or most of us the potential — almost always hard won and seldom truly accessed — to employ evolutionarily novel intrapsychic maneuvers, learned from our most sophisticated ancestors, to weaken or “get ahead of” the above-mentioned regulatory mechanisms. Here I am referring to introspective techniques that help us see our own mental operations more objectively, not techniques that just lead to relaxation or greater happiness. This unnaturally objectified seeing can happen in real time (best) or during reflection upon past events (dicey).

An analogy, accidentally constructed by the Wachowskis (?), for using the introspective techniques I’m referring to is vividly given in “The Matrix” trilogy, when Morpheus and his team, eventually especially Neo, purposely send their minds into the matrix via skillful intrapsychic hacking procedures. They are not going in there to sunbathe… even though that would be nice. They cannot. The regulatory mechanisms that already are in place are quite, albeit imperfectly, adaptive in real time. They have the ability to learn. They are seldom are far behind and their prime mandate is to encapsulate or literally destroy the complex neural circuits (i.e, symbolized by Matrix characters like Trinity, Morpheus, Mouse, Sipher) that may collaborate to enable biologically subversive attempts at gaining deep objective self-knowledge. These regulatory mechanisms are key to biologically adaptive neurodevelopment, and they are extraordinarily resourceful and ruthless. They may be limbically based, but any part of the brain can be recruited to help them fulfill their mission, as was “The Matrix” character Sipher.

My own mind largely has been ruined, I feel, by engaging in this process. A lot of my essential “freedom circuitry” has been repeatedly hammered. But, I still believe success is possible for some, particularly if they can learn from the mistakes and rare successes of others. Call it faith in consciousness.

A new analogy has hit me. We are born into a cognitive-emotional prison cell full of delights as well as sources of suffering. (As per astute Buddhist teachings, it’s really all suffering.) But, we may notice that hanging from the ceiling, outside the cell bars but more or less within reach, there are various sets of shiny keys. Usually, one of them opens our cell door. Others keys in the set open additional doors spread throughout an unknown intrapsychic labyrinth. Opening some of those doors triggers an instant alarm, others a delayed alarm, maybe others no alarm at all, especially if the key is inserted and turned correctly. Some sets of keys open doors that lead to traps and cul-de-sacs. You can easily end up in a seemingly nicer jail cell. Or a worse one. Perhaps you can end up in enticing cells, but with no keys hanging outside the bars. It may be hard to tell if one has progressed in any meaningful way.

A legitimate teacher, or cultural tradition, and/or a modern scientific tradition may help us learn something of the labyrinth, and which set of keys to pick that lead to real freedom, or at least time-limited degrees of it. We can learn to go farther and farther.  But the prison is larger and more complex than we typically can conceive, especially anywhere near to our starting position, and especially if we try to do so alone.

Perhaps the best path is right around a nearby intrapsychic corner. But if anyone tells you so, beware. — Paul

The Singularity is Near: When Humans Transcend Biology

Kurzweil builds and supports a persuasive vision of the emergence of a human-level engineered intelligence in the early-to-mid twenty-first century. In his own words,

With the reverse engineering of the human brain we will be able to apply the parallel, self-organizing, chaotic algorithms of  human intelligence to enormously powerful computational substrates. This intelligence will then be in a position to improve its own design, both hardware and software,  in a rapidly accelerating iterative process.

In Kurzweil's view, we must and will ensure we evade obsolescence by integrating emerging metabolic and cognitive technologies into our bodies and brains. Through self-augmentation with neurotechnological prostheses, the locus of human cognition and identity will gradually (but faster than we'll expect, due to exponential technological advancements) shift from the evolved substrate (the organic body) to the engineered substrate, ultimately freeing the human mind to develop along technology's exponential curve rather than evolution's much flatter trajectory.

The book is extensively noted and indexed, making the deep-diving reader's work a bit easier.

New gene editing method modifies non-dividing cells in brain

Until now, gene editing has relied on cell division to propagate modifications made with techniques like CRISPR Cas9. Researchers at the Salk Institute have devised a new method that can modify the genes of non-dividing cells (the majority of adult cells). They demonstrated the method’s potential by inserting missing genes into the brains of young mice that were blind due to retinitis pigmentosa. After the team inserted fully functional copies of the damaged gene responsible for the condition into the relevant visual neurons, the mice experience rudimentary vision.

Team leader Izpisua Belmonte says of the new method, homology-independent targeted integration (HITI), “We now have a technology that allows us to modify the DNA of non-dividing cells, to fix broken genes in the brain, heart and liver. It allows us for the first time to be able to dream of curing diseases that we couldn’t before, which is exciting.”

While the team, naturally and appropriately, envisions therapeutic uses, could this method be used to modify brain function non-therapeutically, to improve normal functioning, for example?

15 Nov 16 Discussion on Transhumanism

Good discussion that covered a lot of ground. I took away that none of us have signed on to be early adopters of brain augmentations, but some expect development of body and brain augmentations to continue and accelerate. We also considered the idea of bio-engineered and medical paths to significant life-span, health, and cognitive capacity improvements. I appreciated the ethical and value questions (Why pursue any of this? What would/must one give up to become transhuman? Will the health and lifespan enhancements be equally available to all? What could be the downsides of extremely extended lives?) Also, isn’t there considerable opportunity for smarter transhumans, along with AI tools, to vastly improve the lives of many people by finding ways to mitigate problems we’ve inherited (disease, etc.) and created (pollution, conflict, etc.)?

TED Talk and PJW Comment

TED talk of possible interest:

Comment I posted there:
Here is an interdisciplinary “moon-shot” suggestion that we should at least start talking about, now, before it is too late. Let’s massively collaborate to develop a very mission-specific AI system to help us figure out, using emerging genetic editing technologies (e.g., CRISPR, etc.), ideally how to tweak (most likely) species-typical genes currently constraining our capacities for prosociality, biophilia, and compassion, so that we can intentionally evolve into a sustainable species. This is something that natural selection, our past and current psycho-eugenicist, will never do (it cannot), and something that our current genetic endowment will never allow cultural processes / social engineering approaches to adequately transform us. Purposed-designed AI systems feeding off of growing databases of intra-genomic dynamics and gene-environment interactions could greatly speed our understanding of how to make these genetic adjustments to ourselves, the only hope for our survival, in a morally optimal (i.e., fewest mistakes due to unexpected gene-gene and gene-regulatory (exome) and epigenetic interactions; fewest onerous side-effects) as well as in a maximally effective and efficient way. Come together, teams of AI scientists and geneticists! We need to grab our collective pan-cultural intrapsychic fate away from the dark hands of natural selection, and AI can probably help. END
