EmergingTechs Nanotechnology, Synthetic Biology, and Geoengineering in the Governance Eye

The second annual Governance of Emerging Technologies conference held in Phoenix AZ May 27-29, 2014 discussed a variety of governance (regulation), legal, and ethical aspects of three areas of emerging technology: nanotechnology, synthetic biology, and geoengineering (climate management).

The prevailing attitude in nanotechnology is much like that in artificial intelligence, “no new news” and some degree of weariness after having experienced a few hype-bust cycles, coupled with the invisibility frontier. The invisibility frontier is when an exciting emerging technology becomes so pervasive and widely-deployed that it becomes invisible. There are numerous nanotechnology implementations in a range of fields including materials, computing, structures, nanoparticles, and new methods, similar to the way artificial intelligence deployments are also widely in use but ‘invisible’ in fraud detection, ATM machine operation, data management algorithms, and traffic coordination.

Perhaps the biggest moment of clarity was that different groups of people with different value systems, cultures, and ideals are coming together with more frequency than historically to solve problems. The locus of international interaction is no longer primarily geopolitics, but shifting to be much more one of collaboration between smaller groups in specific contexts who are inventing models for sharing knowledge that simultaneously reconfigure and extend it to different perspectives and value systems.

Fundamental Advances in DNA Nanotechnology: Probes, Synthesis, Photonics, and 3D Printing

The focus of the 11th annual conference on the Foundations of Nanoscience (FNANO) held April 14-17, 2014 in Snowbird UT was self-assembled architectures and devices. The conference continues to be important in providing a comprehensive look at fundamental enabling technologies across a range of nanoscience fields and the eventual advent of molecular electronics.

The majority of the conference discussed self-assembled architectures and devices in the context of DNA nanotechnology (using DNA as a structural building block in nanomaterials construction). DNA is the material of choice for constructing nanoscale objects. It is a useful construction material because the interactions between complementary base pairs are understood, and can be designed and built to create frames and scaffolds that hold other molecules and create structures on their own.

The main technique in DNA nanotechnology is inducing self-assembly, where advances in different methods were discussed such as lithography, 3D printing, electro-chemicals, electronics, and photonics (controlled light interactions with matter).

The scale and required replicability of nanomaterials engenders a strong focus on tool development to determine and assess the progress and quality of self-assembly and other operations. New research was presented in tools related to working with DNA such as probes, detectors, samplers, nanopores, and nanochannels (i.e. waldoes). In silico modeling and prediction remains a crucial step, for example improving the prediction of DNA and RNA folding helps in targeting RNA interference.

Synthetic biology, biomedicine, energy, and basic materials continue to be the important application areas for DNA nanotechnology.

Further advance in the integration of organic and inorganic matter

A fundamental research focus in nanotechnology is the deliberate creation of organic-inorganic hybrids such as rotaxanes that have the properties of both organic and inorganic matter. These nanomaterials can greatly extend the range of control and manipulation that can occur in nanomedicine and other applications.

One interesting recent example is engineered fusion proteins, inorganic-binding peptides conjugated with bioluminescence proteins. The fusion proteins can be used as bioimaging molecular probes both targeting minerals (through fluorescence labeling) and monitoring the rate of biomineralization (through induced reactions). (Yuca et al., Biotechnol Bioeng. 2011 May;108(5):1021-30.)

Another example (Figure 1) is graphene sheets sandwiched in the hydrophobic interior of a phospholipid. The phospholipid layers of the membrane electrically isolate the embedded graphene from the external solution which means that the composite system could be used in the development of biosensors and bioelectronic materials.

Ultimate possibilities for life and technology

Thinking really long term, what would it be like if all matter, including life, could be designed and built to specification with nanotechnology and synthetic biology? Form factor could become ephemeral and purpose-driven. An intelligence could embody as a human, as a fleet of starships, as a crane, as a school of nanoparticles, or remain digital.

Some interesting issues could come up, say from having multiple persistent copies of one intelligence. What would the social, legal, economic etiquette and governing laws be? Or would these words even make sense anymore? The notion of the distinct individual may become obsolete.

Transhumanism will be an interesting and certainly divisive step, when groups or all humans have radically enhanced capabilities as compared with today. Posthumanism, the moment of speciation, may be quite a shock.

What about utility functions? In a digital format, traditional biological functions make a lot less sense. And what about emotion? Is there a relevant adaptation for the digital substrate or is emotion just another biology-based information system?

What is intelligence and is it reflected differently in a digital medium without the sensory input context of the physical world? Maybe intelligence is nothing more than manipulating patterns of information.

Finally, what are the ultimate possibilities for life and technology once joined? What if any would the activity be? Would the focus be on aesthetics? Analytics?

Our beautiful future

As worldwide over-dependence on oil and the costly Iraq war has hastened the way for new energy regimes, the U.S. financial bailout will be hastening the use of economic models other than Darwinian capitalism as it has been known where the most able seize maximum resources for themselves. Nascent social movements for opting out of the traditional economic system will become stronger. Science fiction is rife with dystopian models of robotic controlled governments (Daniel Suarez’ Daemon is a recent example) but in many ways machine-like entities absent the agency problem could be a dramatic improvement over fallible people-administered governments. Technology is more often humanifying than dehumanifying.

As usual, the focus is on technological advances to remedy the current global energy, resource consumption and economic challenges. Given both history and the present status of initiatives, technology is likely to deliver. New eras may be ushered in even more quickly when demand is higher and complacency lower. A surveillance and sousveillance society is clearly emerging, simultaneously from top-down government and corporate programs and bottom-up individual broadcast of GPS location and other lifestreaming. The trend to freeing human time for productive and rewarding initiatives is continuing. What will be the first chicken in every pot, the robotic cleaner or self-cleaning nanosurfaces? How soon can all jobs be outsourced to AI? How soon will there be options on the nucleotide chassis?

Fallacies when thinking about the economics of future technology

Future technologies seem so impactful and fabulous that it is easy to jump to incorrect conclusions about what things would be like with their advent.


Fallacy #1: Molecular assemblers will have a worldwide overnight rollout
The conventional assumption is that once humans are able to make one molecular assembler, it will be able to self-replicate, and therefore within twenty-four hours everyone worldwide will have one. It is far more likely that a molecular assembler would follow the usual s-curve adoption pattern of any other newtech; early versions are expensive and clunky with minimal functionality, continued improvement iterations make the newtech more relevant and usable.

The first molecular assemblers may be like a next generation 3d printer, printing the T-shirt a friend sent as an email attachment. Only early adopters will have the utility (read: money and interest) to purchase the first molecular assemblers. Also, the first molecular assemblers will not be able to self-replicate as the intricate molecular manufacturing processes will need to be conducted at special facilities.

Finally, the full newtech ecosystem needs to be considered, while carbon and other basic elements could be obtained easily from dirt piles delivered to suburban driveways, industrial utility solutions are need for the 50% of the urbanized world. Cartridge supply for specialty elements (think Gillette) will be required. Matter decompiling will need to be a feature of the molecular assembler or there will need to be some other means of recycling. More here, here and here.


Fallacy #2: Don’t develop newtech if it’s not cheap enough for universal access
This is the view that we should not develop any beneficial newtech unless it can be immediately accessible worldwide at a low price. “Folks, lets not make the Eniac since not everyone can have one.” However noble this view may be, it again ignores the historical precedent of technology development, rollout and penetration. A fundamental property of technology is that it may be expensive at the outset but then price drops, functionality improvements and re-purposing to new markets occur over time. For example, those currently paying $100,000 a year for life extension treatments are hopefully helping to rationalize, standardize and develop a broader market for these services.

Work can still be done on open-source and universal accessibility models, and diligence applied to clearing public goods to non-IP protected regimes (e.g.; the human genome), but with the understanding that traditional technology development models (cost drops over time) will continue to drive progress.

In fact, there can be benefits in not adopting newtech immediately; costs are higher, unintended consequences are unknown, early adopters can work out the kinks (e.g; the first generation iPhone cost $600, the second generation iPhone 3G with expanded functionality emerged a year later at $199) and older technology generations like landline telephony can be skipped. World-is-flat cycle time speed-ups and new business models (e.g.; OneWorldHealth as a non-profit pharmaceutical company directed at developing world disease) illustrate market efficiency in applying traditional technology development in today’s world.

Post-scarcity economy

The long-term future economy is a post-scarcity economy (PSE), where substantially all human material needs are easily met at low cost or for free. The term post-scarcity economy is a bit of a misnomer since only the scarcity of material goods is likely to recede. The economy itself and scarcity as an economic dynamic will probably persist, for example, scarcity of time, energy, processing power and creative ideas.

The future economy will likely be realized in phases. Some material goods would be replaced or provided at near-zero cost at the outset, perhaps certain classes of items or goods like fuel, then more items such as food, then substantially all material goods. Fancier items like high-end designed objects and medical treatments would probably not be available in the earlier phases.

What will happen to services as material goods are increasingly provided at minimal cost? Initially services would be unchanged, but over time, nearly all current services could be replaced by technology-advanced near-zero cost alternatives. As Josh Hall suggests in Nanofuture, nanobots could provide daily hair-trimming and nano-foglets could create new hairstyles on demand. Robots are already available for lawn-mowing upkeep (Robomow). Telemedicine could be used for medical diagnostics and treatments. Artificial Intelligences (AIs) may be consulted for tax and stock advice.

Over time, public services such as police and fire protection could be provided by trusted AI networks and other mechanisms. Wireless sensor networks and cams may shift the nature of crime and policing activity. Future building materials may be impervious to fire and possibly self-reconstruct following earthquakes or other damage.

New virtual and other non-traditional services requiring intelligent attention from AIs or human minds, particularly in providing entertainment, learning and means of interesting and productive engagement, will probably be a growth area. The future economy will likely be transacted with multiple currencies, a variety of monetary currencies and additional supplementary currencies such as time, attention, intention, reputation and ideas.

Civilized transition to the post-scarcity economy

Contemplating a new era of bountiful resources compared to previous times, some call for a socialist, or equal, distribution of the new resources. Two examples of new eras would be those triggered by the advent of the molecular assembler and uploaded human minds; the resources would be, respectively, Earth and Solar System matter and processing capacity.

A socialist resource allocation is moot because:

  1. At t+1 or t+n, there will have been a reallocation of resources based on individual skill, utility and Darwinism,
  2. Capitalist forces will figure out how to attain more of the resources in other ways,
  3. Ways of enforcing a socialist resource distribution will probably not exist or be desirable, and
  4. Market mechanisms are likely to provide the most effective resource distribution.
Much more important than which post-scarcity economy resource allocation model to use is how to engender a smooth transition to the new era.
Presumably the rule of law will persist and the critical part will be adapting it to extend and protect rights in the new eras. What is going to happen when someone erects a Dyson sphere around newly terraformed Mars homesteads and starts levying a toll on IP traffic and physical egress? Law seems to be the most stable profession in the face of accelerating technology and new eras!

Absent UN AI Peacekeeping Forces, there should be a way to design incentives backed by consequences and force if necessary to reduce the claim-jumping, lawlessness and vigilanteism (its new guise: nano-weaponry arms races!) that has accompanied historical landgrabs.


Reference:
At the end of “Engine of Creation,” Eric Drexler discusses “Inheritance Day,” a time for “distributing ownership of the resources of space” in three possible scenarios:
  1. (capitalist) First-come first-served, a landgrab as homesteading and mining claims have occurred traditionally. Dismissed since the first one to arrive with an appropriate molecular compiler could to re-work and thus claim as far as it could reach in the universe,
  2. (socialist) Equal distribution and recalibration over time, and
  3. (socialist) One-time equal distribution – the libertarian and most preferable approach

Long-term impact of the molecular assembler

As described in Molecular Assembler Adoption and Molecular Assembler Impact on Society, while the initial roll-out of molecular assemblers may be the usual multi-year S-curve of technology adoption followed by a period of slow social change for adjustment to the widespread presence of molecular assemblers, at some point, social and political change will likely become more radical.

'God assembler'
The initial simple molecular assemblers may only be able to provide for basic survival needs but would presumably give way to ‘god machine’ assemblers that could produce health diagnostics and remedies, nanotechnology, sophisticated electronics including self-aware robots and any other required or requested objects of the time, as well as recycle unwanted material.

Societal organization
Right now society is organized around a variety of cultural groupings: family, education, work, interests (hobbies, religion, sports, alumni, community activity), and per political and geographical boundaries. With molecular assemblers, virtual reality and nanotechnology, there is no reason for these traditional groupings to persist. The work imperative dissolves. Political and geographical boundaries may become meaningless. Anywhere interaction occurs, virtual reality environments will be indistinguishable from physical reality and perhaps preferable in many ways.

In a mature molecular assembler society, what happens to the basis of physical location?
Existing land would still be somewhat scarce, but it might be possible to create additional land or stable novel residential structures in oceans, rivers and bays. For example, the Pacific Garbage Patch could be collected into a foundation for a vacation destination and a transportation, trade and conference hub between the U.S. and Asia (“The PGP Convention and Visitors Center is pleased to host CES 2020”).

Molecular assemblers and super strong nano structures could create much denser comfortable habitation on existing land (kilometer high skyscrapers) allowing existing and new cities to flourish and grow. The improved technology could also be used to easily build and inhabit many more environments. Removing physical proximity requirements for work, education and activities would allow people to fan out across the globe and eventually into space.

Molecular assembler impact on society

A recent post postulated that molecular assembler adoption is not likely to be an overnight roll-out, but more like the S-curve uptake of any technology product (TiVo, iPod, etc.) due as usual to cost, availability (particularly of element canister refills) and application.

Once molecular assembler roll-out starts, how is it likely to impact society?

It is assumed that all items necessary for survival can be made with the molecular assembler: food, shelter, basic medicines, etc.

Does this mean everyone will immediately quit their jobs and the world will turn to chaos?

No. While survival basics will be available from the molecular assembler in its initial form, many items and premium versions of basic items will not. Like the S-curve of assembler roll-out and adoption, the capability of what can be manufactured is also likely to grow over time. Businesses (Ponoko is a current example) and communities will arise to provide product designs for sale and share via the Internet. Expansion cartridges with elements other than the basic CHON stream (carbon, hydrogen, oxygen and nitrogen) may be added or available at a community level for the construction of more exotic items.

How will the structure and activity of society change?

In the first phase, persisting for perhaps five years, society's structure and activity will slowly start changing. The norm is likely that people will continue to work for several reasons discussed below and that together with the static availability of land and locations of schools and universities will probably keep people organized around their traditional activities and groupings for some time.

  • The post-scarcity economy (PSE) has not yet been fully realized. Many things must still be purchased: premium items, services, content, entertainment, non-assemblable items, designs and inputs for assemblable items, land
  • Habit, risk aversion (unclear how the new phenomenon will unfold and whether it will persist), maintaining status quo while creating future plans, emotional reasons (static comfort in the face of great change)
  • Work is a venue for garnering status, participating, engaging in productive activity, actualizing
In fact, professional focus, activities and responsibilities will be shifting in interesting ways to accommodate, create and take advantage of the new ways of controlling matter. The molecular assembler industry will spawn many businesses from the manufacture and distribution of assemblers to element canister supply to design creation and implementation. Information economy businesses will be impacted and all matter based businesses will need on-site reinvention. The service sectors of the economy will explode as even if basic materials become free, if AI and robotics have not evolved similarly, labor will not.

Molecular assembler adoption

What would the technology adoption curve for the molecular assembler look like? A molecular assembler is a home appliance which would sit on a countertop supplied by water, element canisters and electricity and make items on demand such as food, clothing or other objects personally created or generated from designs found on the Internet.

Molecular Assembler, e-Drexler.com
As with other technologies like the personal computer, cell phone, Internet, TIVO/DVR, iPod, etc., there would likely be a gap between launch and widespread adoption. Not everyone wants to or can be an early adopter. People watch new technologies as their friends and other people buy and use them; they assess the price point for value and killer app-ability and adopt when it becomes personally relevant and possible. Although the time curves are increasingly compressed, it is still taking a few years for technologies to reach mainstream penetration.

Theoretically, the molecular assembler adoption curve could be much quicker than with other technologies because the dream of a machine that can make anything is of course that it can make copies of itself so that everyone can have one. While this may be the ultimate result, it is unlikely in the first phase since the intricate nanoscale molecular machinery components of the molecular assembler will need to be manufactured and assembled at special nanotechnology facilities. The first molecular assemblers will likely quite expensive.

Even when molecular assemblers can be manufactured or copied with ease, the supply canisters need to be considered. The element cartridges for the main CHON stream, carbon, hydrogen, oxygen and nitrogen, plus specialty element cartridges are conceptually similar to laser printer ink cartridges. The element cartridges will need to be manufactured and distributed (e.g.; head over to Fry’s for a hydrogen cartridge) or there will need to be local refilling stations, possible via the existing gas or food distribution channels. Eventually, there could be utility feeds into communities or houses with measured usage.

Governments, having every interest in a stable transition to the molecular assembler and the post-scarcity economy (PSE), would likely regulate or otherwise attempt to control the distribution and refilling of element cartridges and possibly the assemblers themselves. Providing assemblers and element cartridges would be big business, attracting corporate and entrepreneurial activity to find effective ways to supply the demand.

Another factor inhibiting the immediate widespread adoption of molecular assemblers would be the need to have a fully developed value chain or offering ecosystem, particularly having some sort of recycling mechanism for unwanted or waste material from the assembler.

In summary, the factors influencing molecular assembler adoption would be like those of any technology adoption: cost, availability and application.

Which sciences are important now and why?

This is a quick and dirty look at which sciences are most important right now. These sciences are: physics, astronomy, nanotechnology, biotechnology, semiconductors, computation and information theory.

The important areas of physics are particle physics at accelerator and detector labs, and anything related to quantum theory/unified field theory/many worlds theory. These areas will help us to understand more about and control the properties of the smallest pieces of matter which are not atoms, not quarks but strings or other.

Astronomy is important because we need to find out more about the rest of the universe, how it works, more about black holes, dark energy and dark matter and how to harness them. Understanding the physics of that which we do not currently understand. This is important for many reasons including our eventual need to move off the Earth (4.5 billion years to the Earth's engulfment by the sun) and out of the galaxy (10 billion years until Andromeda collides with the Milky Way).

Nanotechnology is important because it will allow us to build and create objects from the ground up, truly mastering our world by creating matter. In addition there are interesting novel properties of atomic level matter which may offer better knowledge of quantum behavior.

Biotechnology is important in being able to improve and redesign ourselves as humans, in the near term to get to baseline by eradicating disease and then to expand from baseline into new enhanced capabilities and forms. As we look to immigrating to other worlds and space colonies, biological transformation will be key.

Semiconductors and computation are important as we need to reach successive tiers of computing capability to further master knowledge about how our universe works, especially regarding large phenomenon like galaxies and small phenomenon like brains. Software is a harder problem than hardware and with greater processing, a lot of results can be achieved by brute force computation and don't need to wait for and rely on more complicated human team work dependent software.

Information theory is increasingly critical as a new conceptual model by which the universe is being explained. Seth Lloyd is one of the foremost authors on this. The idea is that there are many forms of information storage and computation in the universe, including life (plants, animals, etc.) who store DNA and compute from it, even rocks reacting to their environment are said to process information. Black holes also take in information, process it and return output, but this phenomenon is tested or understood yet.

These sciences share the theme of helping us answer the biggest remaining outstanding questions the fastest. Who are we? Where did we come from? What is the nature of this universe? Are there other universes? What are the physical laws that govern all matter and phenomenon of this universe?
