Art opens the show by greeting his audience and introducing his guest, Robert Bigelow, a close friend and collaborator over the years. Robert Bigelow is known for his work in aerospace, having founded Bigelow Aerospace in 1999. The company focuses on creating cost-effective space stations and transportation systems for private enterprise use. Art shares a personal anecdote about Bigelow offering to send a helicopter to pick him up for a tour of Bigelow Aerospace, showcasing Bigelow’s generosity and character.
The conversation shifts to Bigelow’s recent accomplishments, including the successful launch of a spacecraft that is functioning well despite the many challenges that could have arisen. The spacecraft, a pathfinder for future expandable habitats, is currently in low Earth orbit at an altitude of 342 miles. The orbit allows for approximately 15 passes over Earth every 24 hours, with mission control based in Las Vegas. Bigelow discusses the materials and design of the spacecraft, noting that while the shielding is not as robust as it would be in a full-scale model, it still provides protection from radiation and space debris.
Art continues his conversation with Robert Bigelow, delving deeper into the technical aspects of the spacecraft’s design. Bigelow describes the robust construction of the spacecraft, including the use of Kevlar-type material and multiple layers of shielding designed to protect against space debris. Despite the significant amount of space junk in low Earth orbit, Bigelow is confident in the spacecraft’s ability to withstand impacts, thanks to the protective architecture tested in hypervelocity impact scenarios.
Bigelow also reveals that the spacecraft is equipped with instruments to detect any collisions, although the likelihood of a catastrophic impact is low. He shares that the spacecraft has some small biological entities on board, such as Madagascar hissing beetles and American roaches, as well as fun items like photographs and toys, which they monitor as they float around in zero gravity. The second flight, scheduled for January, will include additional creatures like scorpions and ants, as well as personal items from individuals.
Art and Bigelow discuss the ambitious vision of expanding Bigelow’s hotel business into space, with the possibility of collaborating with major hotel chains or corporations to establish facilities in orbit. Although no formal discussions have taken place yet, the success of the first flight has set the stage for future developments. Bigelow mentions that the spacecraft is also equipped with 13 cameras, seven external and six internal, to capture video footage, with plans to increase this number in the upcoming flight. While they haven’t captured anything unusual on camera yet, Bigelow acknowledges that they have plenty of time to make intriguing observations.
Art and Robert Bigelow continue their discussion, focusing on the technical challenges faced in stabilizing the spacecraft. Initially, the spacecraft was in a slow tumble, causing interruptions in signal transmission. However, they managed to stabilize it using torsion bars and magnetic attitude control equipment, significantly improving the quality of the video signals, both external and internal. They are now able to capture clear views of the Earth and, occasionally, the moon.
The conversation shifts to the fate of the biological entities onboard, specifically the bugs. Although they provided sufficient nutrients and water for multiple generations, there is uncertainty about whether the bugs have survived. The lengthy process from packaging the spacecraft to launch, which involved violent shaking and exposure to a vacuum, may have been too much for them. Surprisingly, a Madagascar hissing beetle survived a two-hour vacuum test on Earth, which was unexpected.
Art expresses disappointment that Bigelow had to send the spacecraft to Russia for launch, highlighting the sad state of the American space program’s capabilities. Despite this, Bigelow’s success with the Genesis spacecraft represents a significant achievement, with the potential for future space accommodations. The spacecraft orbits the Earth every 100 minutes, serving as a precursor to possible space tourism ventures.
Art and Robert Bigelow discuss the limitations of the American space program, particularly the high costs and limited availability of launch vehicles in the U.S., which forced Bigelow to launch his spacecraft from Russia. Bigelow expresses hope for changes in the future but acknowledges that the current situation in the U.S. is dire, with fewer options for economical launches. He highlights the challenges of competing with the established commercial communication satellite launches, which dominate the market.
The conversation turns to the historical context, noting that the shuttle program initially monopolized satellite launches, leading to the Challenger disaster and the realization that multiple launch options were necessary. With the shuttle program nearing its end and only two out of the original five shuttles remaining, Bigelow is concerned about the risks involved in completing the remaining 16 missions by 2010. Beyond 2010, the U.S. will lack a transportation system until at least 2014, with doubts about the success and affordability of the Crew Exploration Vehicle program.
Art and Bigelow discuss potential alternatives, such as SpaceX’s efforts under Elon Musk to develop the Falcon 1 and larger launch vehicles, which could provide a competitive option for U.S. launches. Bigelow remains cautiously optimistic, recognizing the importance of staying connected with launch companies as they are essential for his ventures.
Art and Robert Bigelow discuss the logistical and technological challenges involved in space exploration. Bigelow mentions the dependence on transportation systems like Russia’s Progress and Soyuz for cargo and crew. Art suggests the idea of placing an amateur radio repeater on a future flight to allow worldwide communication, which Bigelow finds intriguing and notes to discuss with his team.
Bigelow recalls the surreal experience of witnessing the successful launch, initially questioning if it was real. He shares that the spacecraft has been visually observed from Earth and that their website provides maps and schedules for when the spacecraft might be visible in different locations. He describes the emotional connection he feels to the spacecraft, likening it to having a “little baby” orbiting Earth.
They also discuss the flight schedule and future launches, with Bigelow revealing that they have a five-year agenda and are focused on ensuring their second flight is successful. Art inquires about the financial aspect, noting that Bigelow has invested around $500 million of his own money into the project over the years. Bigelow acknowledges the financial risks, mentioning that space ventures have historically been dangerous and financially ruinous for many.
Art and Robert Bigelow wrap up their discussion with reflections on the financial and strategic aspects of space exploration. Bigelow mentions the high-risk nature of the industry, citing the example of Kessler Aerospace, which went through $800 million. He emphasizes that investing in space ventures is a leap between “crazy and philanthropic,” and advises potential investors to wait until a reliable revenue stream is established.
Despite the challenges, Bigelow remains committed, having used net income rather than capital to fund his projects. He anticipates that the first space tourists might be able to fly by around 2011, though it will be expensive. The initial focus will be on validating the spacecraft with professional astronauts before opening it to tourists. Art praises Bigelow’s vision and courage, urging the American aerospace industry and government to take similar risks to avoid falling behind globally.
As the segment concludes, Art expresses his admiration for Bigelow’s achievements and introduces the next guest, Sir Charles Shults, who will discuss nanotechnology. Shults has an impressive background, having worked on various advanced weapons systems and conducted research in nuclear fusion and robotics.
Art begins his conversation with Sir Charles Shults III by introducing the topic of nanotechnology, a field that allows manipulation at the atomic level. Shults explains that nanotechnology involves working with structures at a scale of nanometers, which are one billionth of a meter. The potential applications are vast, from creating new materials to performing repairs on things too small to handle otherwise. He mentions that most initial nanotechnology devices will likely be on the scale of viruses and will require advanced microscopes like scanning electron microscopes or atomic force microscopes to be seen.
Shults highlights the early development of nanotechnology, recalling IBM’s work using a scanning tunneling microscope to manipulate atoms and form the letters “IBM” on a piece of chilled metal. This marked the beginning of intentional atomic manipulation. However, he notes that communication between scientists working in different fields is often limited, as they tend to focus on specific technologies in small groups and are cautious about sharing their findings.
Interestingly, Shults points out that science fiction has played a significant role in inspiring and driving scientific development, as ideas from science fiction often find their way back into real-world research. He suggests that scientists could benefit from reading science fiction to explore potential advancements in their fields.
Sir Charles Shults III continues his discussion on nanotechnology, introducing the concept of impact armor—a garment that hardens upon impact to protect the wearer, similar to a bulletproof vest but significantly more advanced. This technology, developed by an Israeli company called AppNano, uses nanoparticles suspended in a lubricant. When struck, the particles cluster together, transforming the material from a liquid to a solid almost instantaneously, with reaction times in the nanosecond range.
The material, which is about the thickness of a thick T-shirt, can withstand impacts up to 250 tons per square centimeter, providing protection that is far superior to traditional Kevlar. Unlike Kevlar, which can stop bullets but still causes significant trauma, this new material dissipates the force over a larger area, reducing the impact on the wearer.
Shults explains that while the material is still in the production scaling phase, with only a few kilograms produced daily, advancements are being made to increase production. This could soon lead to the availability of “bulletproof T-shirts.” Art and Shults acknowledge that while the potential benefits of nanotechnology are immense, there is also a dark side that could lead to misuse, a topic they plan to explore further.
Art and Sir Charles Shults III delve into the potential dangers of nanotechnology, discussing how nanotech weapons could be almost invisible and extremely difficult to detect. Shults explains that while new detectors using nanotechnology might help find such weapons, the challenge lies in their ability to be hidden effectively. The conversation touches on the concept of “gray goo,” a scenario where self-replicating nanomachines could consume everything in their path, turning the world into a mass of “gray goo.”
Shults points out that unlike biological weapons, which are often fragile and self-limiting, nanotechnology could create resilient machines capable of lying dormant for extended periods. Art expresses concern about the potential for such technology to cause uncontrollable destruction if it could convert various materials like dirt, metal, or plastic into more disassemblers.
When asked who is leading the research in nanotechnology, Shults mentions that while some work is being done in the private sector, the majority of research is conducted in universities under government funding. Agencies like the Department of Defense are particularly interested in applications such as detecting explosives, with examples like the “nano dog” developed in Israel, capable of detecting explosives at extremely low concentrations. Additionally, nanotechnology is being explored for creating new materials, drug delivery systems, and information storage devices.
Art and Sir Charles Shults III continue their discussion, transitioning from nanotechnology to its implications for computing, particularly in relation to Moore’s Law. Moore’s Law, which predicts that processing power doubles approximately every 18 months, has driven advancements in computing for decades. However, Art questions whether this trend has slowed recently, as clock speeds seem to have plateaued around 3.5 to 4 gigahertz.
Shults explains that while clock speeds may not be increasing as rapidly, manufacturers are now focusing on increasing the number of cores on a chip, allowing multiple instructions to be processed simultaneously. This shift towards parallel processing still adheres to Moore’s Law in terms of overall computational power, even if the speed of individual processors isn’t doubling as before.
The conversation then shifts to the future of computing with nanotechnology. Shults describes how nano-computers could function as mechanical devices at the molecular level, capable of processing billions of instructions per second in an incredibly small space. He explains that while binary logic remains the standard, future systems might explore more complex logic states, though this would complicate design.
Art raises the question of whether computers, particularly those enhanced by nanotechnology, might one day achieve consciousness. Shults suggests that this could occur through the organization of numerous simple processors working in parallel, potentially surpassing the capabilities of the human brain.
Art and Sir Charles Shults III explore the ethical and existential dilemmas associated with advanced artificial intelligence (AI) and nanotechnology. Shults explains that achieving consciousness in a machine would require not just sophisticated hardware but also complex software that mimics human learning and perception. The potential benefits of such intelligent machines could be enormous, but the risks are equally significant. Shults speculates that an AI might, for example, decide to intervene in global conflicts “for our own benefit,” potentially leading to unintended consequences.
They discuss the need for incorporating safety measures, such as the famous “Three Laws of Robotics,” but acknowledge that a highly intelligent machine might choose to ignore them. The conversation turns to the potential medical applications of nanotechnology, including breakthroughs like using gold nanoparticles to treat Alzheimer’s disease. These particles can be infused into brain tissue and then activated with low-level radio waves to break up Alzheimer’s plaques, offering a promising treatment.
However, Art and Shults also touch on the darker side of such technology. They discuss the possibility of using nanotechnology for harmful purposes, such as creating targeted weapons that could destroy crops or even specifically target certain populations. The potential for misuse of these powerful technologies underscores the need for careful consideration and regulation.
Art and Sir Charles Shults III continue their conversation about the potential dangers and advancements in nanotechnology. Shults highlights the real threat of targeted viruses that could use nanotechnology to identify and kill specific populations based on genetic markers. Although Shults doesn’t have direct knowledge of such research being conducted, he suggests that it’s likely being explored due to its tempting potential for use in warfare or other nefarious purposes. Art expresses concern about humanity’s slow social development compared to the rapid advancement of such technologies, noting that many people tend to shut down when confronted with complex issues like these.
Shults then shifts the conversation to more positive applications of nanotechnology, particularly in energy storage. He discusses two recent developments: the first involves bacteria that can consume metals and produce conductive nanowires, which can be used in battery electrodes to increase surface area and current delivery. The second development is the creation of ultra-capacitors using carbon nanotubes, which could revolutionize energy storage by allowing for rapid recharging and high storage density. Shults mentions that work on these ultra-capacitors is being done at MIT, marking the first significant breakthrough in battery technology in two centuries.
Art points out that while some scientists may be skeptical about the potential of nanotechnology, the advancements Shults describes suggest that the technology is already making significant strides.
Art and Sir Charles Shults III continue their discussion on the advancements and potential applications of nanotechnology, particularly in the field of energy storage. Shults explains that new types of capacitors developed using nanotechnology could compete with traditional batteries and even fuels. These ultra-capacitors could allow for rapid recharging—potentially in just a minute or so—while providing enough energy to power an electric vehicle for hundreds of miles.
They also discuss the efficiency of electric vehicles. Although these new storage systems might reduce the weight of the vehicle, leading to better efficiency, the overall energy consumption may still be higher compared to internal combustion engines. The pollution might be reduced at the vehicle level but is simply relocated to power plants, and losses in energy transmission from the power plant to the vehicle further complicate the issue.
Art brings up the significant costs associated with electricity transmission, noting that in the Philippines, the electric bill clearly breaks down these transmission losses, which are substantial. Shults suggests that nanotechnology could help reduce these losses by developing materials with properties that do not exist in nature. For example, carbon nanotubes, which are already showing promise in laboratory experiments, could be used to create wires with conductivities equal to or better than metals. These advancements could lead to more efficient transmission of electricity and reduce the associated costs.
As the conversation moves forward, Shults touches on the potential for creating superconductors that work at room temperature using nanotechnology, which could revolutionize how electricity is transmitted and used.
Art and Sir Charles Shults III continue their discussion on the implications of nanotechnology, touching on its potential uses in space exploration and even terraforming other planets like Mars. Shults explains that nanotechnology could theoretically be used to send tiny, dust-sized nanomachines to other planets, where they could replicate and build everything needed for human colonization, including producing metals, plastics, and even food. This idea mirrors concepts seen in science fiction, like the “Genesis bomb” from Star Trek, where an entire planet’s ecosystem could be reconstructed or even erased and rebuilt from scratch.
They also discuss the lack of oversight in the rapidly advancing field of nanotechnology. Shults points out that, as of now, there are no specific laws or regulations governing nanotech research, making it difficult to control or predict the outcomes of such research. The complexity of the technology and the potential for unforeseen consequences make it challenging to establish effective oversight.
Art expresses concern about the potential dangers, such as the “gray goo” scenario, where self-replicating nanomachines could consume everything in their path. Shults suggests that, similar to how antivirus software works in computers, there could be anti-nanotech measures in place to prevent or mitigate such disasters. However, the efficiency of gray goo and how quickly it could spread is still a worrying prospect. Shults estimates that it might take days or weeks for such a scenario to unfold, but even that timeframe offers limited opportunities for intervention.
The conversation underscores the dual-edged nature of nanotechnology, with its incredible potential benefits and equally significant risks.
Art and Sir Charles Shults III continue exploring the profound implications of nanotechnology, discussing both the potential benefits and the significant risks. Shults mentions that in the event of a “gray goo” scenario, where self-replicating nanomachines start consuming everything, one possible method to stop it would be the use of x-ray lasers. These could disrupt the operation of the nanomachines, effectively destroying them.
They also discuss the potential of nanotechnology to extend human life to the point of immortality, by repairing or replacing any part of the body, including the brain. However, Shults points out that immortality could have severe consequences, particularly regarding overpopulation. He suggests that those opting for such treatments might need to agree to become sterile to prevent the planet from being overwhelmed by an immortal population. The conversation takes a darker turn as they contemplate how immortality could be abused, such as through repeated torture of individuals who cannot permanently die.
Shults also touches on current real-world applications of nanotechnology, such as paint that generates electricity from sunlight, and the concept of liquid metal that could be used for various purposes, including camouflage. However, he warns that the widespread adoption of nanotechnology could devastate the economy. If everything could be easily and cheaply manufactured using nanotech, traditional industries and jobs would become obsolete, leading to a world where there might be no need for money as everything would be essentially free.
Finally, they discuss the concept of a space elevator made of nanotubes, a potential future technology that could revolutionize space travel. Shults confirms that this idea is still being considered, though it has not yet been realized.
Art and Sir Charles Shults III continue their conversation by discussing the ongoing development of the space elevator concept. Shults mentions that companies like LiftPort are already testing systems that could eventually lead to a functional space elevator. They are using tethered balloons with high-tensile strength cables to test cable climbers, which could be used for various purposes, including wireless internet services. This technology involves using a balloon to lift communication hardware into the atmosphere, providing wireless service to surrounding areas.
They also discuss the challenges in creating perfect carbon nanotubes, which are essential for the space elevator. Shults suggests that with further advancements, including annealing processes, these challenges can be overcome, making the space elevator a reality.
The conversation then shifts to the broader implications of nanotechnology, particularly its potential to upend the economy and intellectual property rights. Shults points out that as nanotechnology advances, people could have nano-factories in their homes, allowing them to create anything they need, rendering traditional patents and intellectual property laws problematic. This capability could lead to a world where forgery becomes irrelevant because copies would be indistinguishable from the originals at the atomic level.
Art compares this to the current digital world, where movies can be duplicated without degradation, and Shults agrees that the material world could face similar challenges. They conclude that as nanotechnology evolves, our reality could become as fluid as a computer game, with the only limits being the laws of physics and the availability of materials and energy.
Shults also touches on the idea of using nanotechnology to create small robots for virtual reality experiences, allowing people to explore microscopic environments without actually being miniaturized.
Art Bell and Sir Charles Shults III prepare to open the phone lines for listeners to ask questions, as they have discussed so much intriguing and potentially world-altering information. Art reflects on the remarkable potential of nanotechnology, agreeing with a listener who quoted Arthur C. Clarke’s famous line: “The technology of a truly advanced civilization is indistinguishable from magic.” Shults concurs, noting that nanotechnology indeed holds the promise of achieving almost anything.
They then discuss the past predictions of widespread robotics, which never fully materialized as imagined. Shults explains that while intelligent robots have been challenging to develop due to software complexities, nanotechnology is likely to advance more quickly, especially in areas like medicine, display technologies, and high-strength materials. He also suggests that nanotechnology will eventually enable the creation of robots indistinguishable from humans, as material science continues to advance.
The conversation shifts to global warming, where Art asks if nanotechnology could play a role in controlling the weather. Shults suggests that nanotechnology could be used to manipulate atmospheric particles to reflect or retain sunlight, potentially regulating the Earth’s temperature. He also offers a controversial and unconventional solution to global warming: detonating hydrogen bombs in remote deserts to create a small-scale “nuclear autumn” that could temporarily cool the planet. However, Shults acknowledges that this approach is unlikely to be implemented, mainly because it wouldn’t be profitable.
A caller named Ronnie from Pennsylvania discusses her thoughts on nanotechnology, mentioning that she foresaw a future where people would focus on atomic-level manipulation. She refers to an incident from 1947 involving extraterrestrial material that could realign its atoms after being crumpled, suggesting this might be an example of nanotechnology. Sir Charles agrees that such self-repairing materials are indeed a potential application of nanotechnology, with early examples already being explored in fields like bridge construction.
Another caller, Randy from Memphis, draws a parallel between the concept of “gray goo” and Kurt Vonnegut’s novel “Cat’s Cradle,” where a form of ice called “Ice-Nine” causes catastrophic environmental changes. Sir Charles acknowledges the connection and agrees that without significant social progress, advanced technologies like nanotechnology could lead to our downfall. He suggests that if humanity reaches the technical level to manipulate such powerful technologies, the Earth could potentially be preserved as a park while humans live elsewhere.
The discussion then moves to Sir Charles’s background in aerospace, defense, artificial intelligence, and robotics, as another caller questions the practicality of these technologies being realized in our lifetime. Sir Charles shares insights from past research on spinal cord injuries, highlighting advancements that could have significant implications but have not been widely publicized. He notes that oxytocin, vasopressin, and nerve growth factors have shown promise in reversing or halting spinal damage in experimental settings, yet these breakthroughs have not been widely adopted or discussed.
This lack of visibility in advancements leads Sir Charles to speculate that the control of information and funding may be influencing what technologies are brought to the public’s attention.
Art and Sir Charles Shults III delve into the complexities of how society might function if nanotechnology reaches a point where material needs are easily met. They discuss the implications of a world where everything is essentially free and easily accessible through advanced technology like replicator boxes. Shults points out that money, as a tool of civilization, facilitates cooperation on large projects and underpins our economy. However, in a future where nanotechnology can provide everything individuals need, the traditional exchange of money might become obsolete, leading to a potential collapse of the societal structure as we know it.
A caller from the Gulf Coast asks about the possibility of living in a utopian society where all needs are met, leading to a focus on intellectual and cultural pursuits. Shults agrees that while this could lead to a utopian society, true happiness comes from overcoming adversity and achieving goals, not merely from acquiring things. He expresses concern that removing adversity might result in a loss of character and humanity, as individuals who have never faced challenges may lack depth and understanding.
Art and Shults discuss the potential dangers of a society where everything is given freely, referencing the concept of a stratified society where individuals must earn their way to higher levels of access to technology. Shults suggests that such a system might be necessary to ensure that people develop the qualities of mind and character needed to responsibly use advanced technologies.
The conversation also touches on the idea that freedom isn’t free and that everything of value must be earned, reinforcing the notion that challenges and hardships are essential to human development.
Another caller from California inquires about the properties of nanotubes, specifically whether they could be wrapped around a piece of iron or ferric oxide. Shults explains that while it’s theoretically possible, nanotubes are extremely small—thousands of times thinner than a human hair—and wrapping them around such materials would likely be ineffective, as their strength is only significant in bulk.
A caller discusses the possibility of using nanotubes to create a superconducting magnet that could operate at room temperature. Sir Charles explains that while the conduction properties of nanotubes are well understood, the technology is still in development. He mentions that room temperature superconductors made from nanotubes could potentially conduct over a thousand amps per square centimeter, but significant advancements and manufacturing processes are still needed, which might take another five or six years.
Art reflects on the potential of nanotechnology to create a world where anything one desires can be produced instantly, drawing a parallel to the science fiction movie Forbidden Planet where characters are destroyed by manifestations of their subconscious. Sir Charles agrees that without control or restrictions, nanotechnology could indeed pose such dangers, necessitating the creation of a “nano police” or sensor systems to detect and neutralize threats.
The conversation then returns to the idea of a utopian society, where access to advanced technologies might need to be earned. However, this would likely perpetuate the divide between the “haves” and the “have-nots.” Sir Charles suggests that even in a world where money no longer exists, a new form of currency, likely based on information, would emerge. This currency could include knowledge, entertainment, or designs for new devices, indicating that trade and value would still be present in some form.
They also touch on the U.S. as an information society, considering whether the country’s focus on information over manufacturing might actually be the right path in the context of a nanotech-driven future.
A caller from Phoenix, Justin, raises a profound question about the concept of resurrection through nanotechnology and whether it would mean losing one’s soul. Shults responds by suggesting that using nanotechnology to repair the body wouldn’t make someone less human, but duplicating a person with all their memories raises complex theological questions about the nature of the soul. He also notes that the effectiveness of resurrecting the dead would depend on the condition of the body, especially the brain.
Art then touches on the practice of cryogenics, where individuals freeze their bodies in the hope that future technology, such as nanotech, will be able to revive them. Shults explains the challenges of freezing, such as ice crystals damaging cells, but also highlights how nanotechnology could potentially repair this damage, offering hope for those who choose this path.
The discussion also delves into the desirability of immortality. Shults suggests that a person’s happiness with immortality would depend on their state of mind. Those with a fulfilling life and continuous challenges might enjoy an extended existence, while those who are naturally miserable might not find immortality appealing.
Another caller, Sophia from Eureka, California, asks if nanotechnology could allow someone to regrow a limb or develop superhuman abilities. The conversation seems poised to explore even more extraordinary possibilities of nanotechnology.
Sir Charles Shults III discusses the potential of nanotechnology to enhance human abilities, such as increasing strength and durability. He explains that while it might be possible to alter the structure of bones, joints, and muscles to create a superhuman, this could lead to unintended consequences, like causing significant damage to the environment around them due to their enhanced strength. This raises concerns about the practical implications of such enhancements.
Another caller asks about the possibility of overcoming inertia using nanotechnology, which could allow for things like 90-degree turns in vehicles without experiencing the usual forces. Shults explains that inertia is linked to mass and gravity, and since we don’t fully understand the underlying physics, it’s difficult to speculate on how nanotechnology could be applied in this context.
Shults then addresses the varying pace at which different aspects of nanotechnology might develop. He predicts rapid advancements in materials, medications, and products, but notes that progress in nano-robotics will likely be slower, primarily due to the complexities of artificial intelligence and the challenge of understanding “thinking.”
A subsequent caller raises the issue of how nanotechnology could be used to curb violent behavior. Shults suggests that individuals who want to benefit from life-extending or medical nanotechnology might need to undergo psychological evaluation. In some cases, nanotechnology might even be used to “edit” a person’s behavior to make them more socially acceptable, though this idea raises ethical concerns about abuse and the nature of such interventions.
A caller inquires about the treatment of Alzheimer’s disease using gold nanoparticles. Shults provides the name of the researcher, Marcello Kogan, from the University of Chile in Santiago, and suggests looking up his work for more detailed information.
Sir Charles Shults III addresses a caller’s questions about the relationship between quantum physics and nanotechnology. He explains that while nanotechnology deals with matter at an atomic level, treating atoms like building blocks, quantum physics involves more complex phenomena like wave-particle duality and entanglement. These concepts are challenging to reconcile with everyday experiences. Shults suggests that while both fields might intersect in the future, they currently operate differently. He also touches on the idea that quantum physics could potentially offer ways to create secure systems or distinguish originals from copies, but the exact mechanisms remain speculative.
The discussion shifts to the concept of replicating a human being, including all memories and thoughts, using nanotechnology. Shults acknowledges that this could theoretically be possible, leading to a duplicate that believes it is the original. However, he raises the profound question of whether such a duplicate would possess a soul, a question that technology might never be able to answer.
Art Bell then brings up the potential societal impact of such advanced technology, specifically the risk that it could be controlled by an elite group, leading to a utopia for some and exclusion for others. Shults agrees that the development of such powerful technology could lead to significant inequality, as those who create and control it might choose to restrict access to maintain their power.
A young caller named Zach, who is a student aspiring to become a nanotechnologist, asks Sir Charles Shults III about various aspects of nanotechnology. He mentions a movie related to resurrection and immortality, discusses the use of nanoparticles in cancer treatment, and inquires about the possibility of turning lead into gold using nanotechnology. Shults confirms that while nanotechnology cannot change one element into another, as it works with existing atoms, the idea of “femto-technology” could potentially allow manipulation at the subatomic level in the future, possibly enabling such transformations.
Shults advises Zach to start by gaining a strong foundation in math, chemistry, physics, and an understanding of the periodic table. He suggests exploring different fields within nanotechnology, such as biological applications, materials processing, or electronics, depending on where his interests lie. Shults also mentions the development of a nano-car powered by light as an example of the diverse applications within the field.
Art Bell then asks Shults what the first commercially available nanotechnology product might be. Shults predicts that it will likely be displays for electronic devices, such as digital paper, which could revolutionize how information is presented, though it might also lead to annoyances like animated junk mail.
Another caller from Winnipeg asks about the potential applications of nanotechnology in animals. Shults explains that nanotechnology could be used for pet identification through genetic analysis, with systems being developed that can perform complete DNA analyses from extremely small samples.
Sir Charles Shults III addresses various questions and comments from callers about the potential and challenges of nanotechnology. A caller from Austin, Texas, raises a question about the implications of living forever, particularly regarding the brain’s capacity to store memories over such an extended period. Shults explains that while our brains might reach a point where they can’t store any more information, nanotechnology could offer solutions like memory upgrades or external storage, potentially allowing us to extend our cognitive capacities indefinitely.
Another caller from Medford, Oregon, asks if nanotechnology could lead to scenarios similar to the “Borg” from Star Trek, where technology becomes malevolent. Shults acknowledges this possibility, noting that nanotechnology could indeed enable the creation of advanced materials and technologies that could be used for both good and evil. He also mentions the development of a new “metamaterial” that could lead to holographic displays floating in mid-air, similar to the “holodeck” technology in Star Trek. However, Shults warns that such immersive technologies might cause people to retreat from reality, as we already see with increasingly engaging video games.
A skeptic from the East of the Rockies line expresses doubts about the feasibility of nanotechnology, particularly at extremely small scales where environmental factors like Brownian motion would make construction difficult. The caller compares nanotech’s potential to “pixie dust,” arguing that large-scale industrial efforts are still necessary for major projects like space exploration. Shults has yet to respond to this skepticism, but the conversation hints at the challenges and limitations that may confront nanotechnology as it continues to develop.
The caller expresses doubts about the effectiveness of nanotechnology, particularly in handling large-scale tasks like splitting a boulder, arguing that traditional methods might be more efficient. Shults counters by highlighting the potential of nanotechnology to work at a molecular level, removing only a few molecules to achieve the same result as brute force, and emphasizing that nanotech could work in ways we don’t fully understand yet.
Shults also acknowledges that if nanotechnology turns out to be less viable in practical applications, it would be discovered quickly, which could mitigate some of the more catastrophic scenarios like the “gray goo.” He points out that while organic molecules might struggle in harsh environments, machines made of metals and ceramics at the nanoscale could be more durable and effective. This suggests that nanotechnology still holds promise, especially in specialized environments.
The caller, despite his skepticism, expresses hope for a technologically advanced future, though he remains cautious about the potential dangers and inefficacies of nanotechnology.
As the show draws to a close, Art Bell asks Shults about any resources he would like to share. Shults mentions his Xeno Tech Research website, where new findings are posted, and notes that he is working on a book, which will have a page on the site soon. He plans to send Art a couple of chapters for review.
