Over the last decade, military theorists and authors in the fields of future warfare and strategy have examined in detail the potential impacts of an ongoing revolution in information technology. There has been a particular focus on the impacts of automation and artificial intelligence on military and national security affairs. This attention on silicon-based disruption has nonetheless meant that sufficient attention may not have been paid to other equally profound technological developments. One of those developments is the field of biotechnology.
There have been some breathtaking achievements in the biological realm over the last decade. Human genome sequencing has progressed from a multi-year and multi-billion dollar undertaking to a much cheaper and quicker process, far outstripping Moore's Law. Just as those concerned with national security affairs must monitor disruptive silicon-based technologies, leaders must also be literate in the key biological issues likely to impact the future security of nations. One of the most significant matters in biotechnology is that of human augmentation and whether nations should augment military personnel to stay at the leading edge of capability.
Biotechnology and Human Augmentation
Military institutions will continue to seek competitive advantage over potential adversaries. While this is most obvious in the procurement of advanced platforms, human biotechnological advancement is gaining more attention. As a 2017 CSIS report on the Third Offset found most new technological advances will provide only a temporary advantage, assessed to be no more than five years. In this environment, some military institutions may view the newer field of human augmentation as a more significant source of a future competitive edge.
Biological enhancement of human performance has existed for millenia. The discovery of naturally occurring compounds by our ancestors has led to many of the cognitive and physical enhancements currently available. In the contemporary environment, for example, competition in national and international sports continues to fuel a race between creation of the next generation of performance enhancements and regulatory bodies developing detection methods. One example of this is the use of gene doping to hone the competitive edge in athletes, an off-label use of gene therapies originally developed for the treatment of debilitating genetic and acquired diseases. Despite the possibility of cancer and a range of other lethal side effects, some athletes consider these an acceptable risk. Might this not translate to adversaries adopting any possible advantage without equal disregard for ethics and safety considerations?
It cannot be safely be assumed all states will share the same ethical, moral, legal, or policy principals as Western democratic societies. Based on developmental trajectories to date, contemporary military institutions should anticipate that all forms of human enhancements, whether relatively benign or highly controversial, will continue to evolve. For contemporary strategic leaders, the key is to anticipate how these developments may potentially impact on military institutions.
Impacts on Military Institutions
Theoretically, future advances in biotechnology may permit the augmentation of cognitive performance. However, given the challenges of biocompatibility of silicon, significant enhancements to human performance in the near future are likely to be found in prosthetics, wearable computing, or human teaming with artificial intelligence. In the longer term, some forms of gene therapy may obviate the need for implants. Noting this, a selection of likely challenges are explored below.
Previously, integration of new groups into the military dealt with human beings.
A first order issue will be group cohesion. Military institutions have deep experience integrating newcomers into their ranks. Fundamental to effective future teaming will be evolving this approach to establish trust and group cohesion between normal humans and those who are augmented. The degree to which military leaders can and should trust augmented personnel to make decisions about saving and taking lives is likely to be an evolutionary process. It also remains to be seen whether or not teams comprised of augmented and non-augmented humans are capable of developing trust. Experimentation and trials are needed to establish whether augmented people will bias away from decisions and input from non-augmented people and vice versa. While institutions can learn from historical integration challenges, there is one essential difference with augmented humans. Previously, integration of new groups into the military dealt with human beings. If augmentation using neurotechnology significantly enhances cognitive function, this may represent a separate and distinct group of future Homo sapiens.
The second challenge will be accessibility. Military institutions will need to decide what proportion of its forces will be augmented. Given that early generations of this biotechnology may be expensive, it is unlikely an entire military institution can be augmented. If so, who will be augmented and why? Military institutions will need to develop a value proposition to ensure physical and cognitive augmentation produces superior outcomes to the use of un-augmented personnel. Yet another question to ask is whether military personnel will be de-augmented on leaving the service. The transition of augmented personnel into a largely unaugmented populace may be traumatic for military personnel, and for society more broadly. Even more severe in its repercussions may be transitioning de-augmented personnel into a populace where augmentation is ubiquitous.
The third challenge will be conceptual. One Chinese scientist, writing in 2006, has proposed military biotechnology offers the chance to shift to a “new balance between defence and attack, giving rise to a new concept of warfare, a new balance of military force, and new attacking power.” While the emphasis of this particular article was on a more merciful form of warfare—about which we should be skeptical—it nonetheless highlights the requirement to rethink what biotechnology and human augmentation means for how military institutions develop warfighting concepts. When humans arrive with cognitive enhancement, a range of tactical, operational, and strategic concepts may become irrelevant. Strategic thinking, using a combination of biological and silicon-based technologies could take organisations in very different directions than is presently the case. It also bears examining whether those with augmentation will enable greater diversity of performance (particularly in the intellectual realm) or if it will lead to increased homogenisation of physical and cognitive performance.
The fourth challenge is obsolescence. A fundamental challenge for humans waging war is that, despite technological advances, one of the weakest links is the physical capacity of the human. As Patrick Lin was written, technology makes up for our absurd frailty. Therefore, might normal humans without augmentation become irrelevant in a new construct where military institutions possess large numbers of physically and cognitively augmented personnel? It remains to be seen whether unaugmented humans might able to compete with physically and cognitively augmented military personnel. The augmentation of humans for different physical and cognitive functions may also drive change in how military institutions operate, plan, and think strategically.
A fifth challenge is military education and training. Traditional military training emphases the teaching of humans to achieve learning outcomes and missions as individuals and teams. In an integrated augmented/non-augmented institution, training methods must evolve to account for the different and improved capabilities of augmented personnel and to blend the capabilities of augmented and non-augmented personnel. Similarly, education for military leaders currently seeks to achieve their intellectual development in the art and science of war. If humans augmented with cognitive enhancements are present, both institutional and individual professional military education will also need to evolve. Learning delivery, as well as key learning outcomes, will have to be re-examined to account for the enhanced physical and cognitive performance of this new segment of the military workforce. Even issues as basic as fitness assessments must be re-examined. Potentially, military organisations could drop physical assessments by automatically augmenting people to the institutionally desired level of performance.
The sixth challenge is one of choice. Command structures demand a reduction in an individual’s free will to refuse such that informed consent is not quite the same as for the general population. And when experimental augmentation options progress to become approved interventions, can we equate a parent considering whether to choose an approved cognitive augmentation option for their child to a soldier contemplating the same when operating alongside augmented peers where the stakes are orders of magnitude greater? How much choice will military personnel have in the augmentation process? Will this be on a volunteer basis or by direction, and what are the moral, legal, and ethical implications of these stances? Speculation that augmentation may become mandatory for some professions may also apply to the military.
The final issue addressed in this article is one of ethics. Research communities are grappling with the ethical and moral implications of augmentation for society as a whole. While the first concern in evaluating the military applications of biotechnology is international humanitarian law, bioethics must also be considered. Ethical considerations pervade almost every aspect of human augmentation, and there are ethical considerations threaded through the other challenges raised in this article. For example, beyond the first order questions of whether we should augment soldiers are issues such as how much augmentation should be allowable. Military institutions should also assess the cumulative effects of multiple augmentations and the consequences of converging augmentation. There may also be a point at which a highly augmented human may cross the human-machine barrier, as well as a range of unanticipated capabilities that emerge from different augmentation combinations.
A Way Ahead
These issues must be informed by those within the biotechnology community, but they alone cannot solve them. Broader involvement by senior military, government, and community leaders is required. One expert in biotechnology has written that “clearly the new forms of power being unleashed by bio-technology will have to be harnessed and used with greater wisdom than power has been used in the past.” If military institutions are to demonstrate wisdom in their investments in biotechnology, they must explore societal impacts as well as effects within military institutions.
“Splitting humankind into biological castes will destroy the foundations of liberal ideology. Liberalism still presupposes that all human beings have equal value and authority.”
It is likely some augmentation will be—at least initially—expensive. It may be beyond the means of most people in society and, potentially, many government and corporate institutions. If only military personnel might be augmented, what are the impacts on civil-military relationships, and who would make this decision? In this construct, it could be unethical to deny the benefits of augmentation to wider society. However as Yuval Harari has noted, this may see a differentiation in how society views augmented and non-augmented people—“Splitting humankind into biological castes will destroy the foundations of liberal ideology. Liberalism still presupposes that all human beings have equal value and authority.” In Western democracies, this poses profound questions about conferred advantage, societal sense of fairness and equality, and the value of individuals within society.
In Western democratic systems, development of regulation, policy, and legal frameworks is not keeping pace with the current tempo of complicated technological advancements. It cannot be assumed other states are allowing these deficits to slow their efforts in biotechnology, not to mention the unregulated efforts of non-state actors. While the focus of the fourth industrial revolution remains predominantly on technologies, perhaps for Australia (and other democracies) it is also these areas which require a complementary revolution in the Whole of Nation enterprise so as to keep up with the pace of change and facilitate systematic assessment of human augmentation implications.
The potential to augment the physical and cognitive capacity of humans is seductive. There will be some who will not demonstrate responsible behaviour in taking advantage of these new technologies. Humans have demonstrated in the past the capacity to responsibly manage disruptive technologies such as flight, atomic weapons, and space-based capabilities. This means thoughtful academics, national security practitioners, and people from wider society must be part of the discussion on why and how biotechnology might be used in future. It is vital for the future of global security, and for the human race, that mechanisms for responsible ethical and legal use of biotechnology are considered and developed. This must occur in parallel with the scientific endeavours to develop new biotechnologies.
