A closer look at strategic affairs and the AI factor

Why in the News?

Concerns about an AI arms race and AGI are rising, but research on AI’s impact on strategic affairs remains limited.

What are the key strategic differences between AI and nuclear weapons?

Strategic Difference	Artificial Intelligence (AI)	Nuclear Weapons
Development and Control	Driven by private companies and research institutions (Eg: OpenAI)	Developed and strictly controlled by state actors
Resource Dependence	No ongoing physical resources needed once trained	Depend on rare materials like enriched uranium, requiring secure control
Global Accessibility	Rapidly accessible and globally developable (Eg: AI in healthcare)	Restricted to a few nations with production and maintenance capacity

How should these affect policy?

Focus on Global Tech Governance: Policies should emphasize international collaboration on AI standards and ethics, not just state-centric treaties. Eg: The OECD AI Principles guide responsible AI use across countries and private entities.
Regulate Private Sector Innovation: Governments must work closely with tech firms to monitor and regulate AI development. Eg: The EU AI Act places obligations on companies deploying high-risk AI systems.
Invest in Civilian and Dual-Use Oversight: Policies should ensure AI developed for civilian use isn’t misused for harmful purposes. Eg: Export controls on advanced AI chips to prevent their misuse by authoritarian regimes.

Why is the comparison between Mutual Assured Destruction (MAD) and Mutual Assured AI Malfunction (MAIM) flawed?

Different Nature of Threats: MAD is based on physical destruction through nuclear weapons, while MAIM assumes AI failure or sabotage, which is less predictable and harder to control. Eg: A nuclear missile has a clear origin and impact but an AI malfunction could be decentralized and ambiguous.
Diffuse Infrastructure: Nuclear programs are centralized and state-controlled, but AI development is global, decentralized, and often driven by private entities. Eg: Open-source AI models can be developed by individuals or startups across countries, unlike nuclear weapons.
Unreliable Deterrence Mechanism: MAD relies on guaranteed retaliation; AI malfunction is not guaranteed nor clearly attributable, making deterrence weak. Eg: It’s hard to prove who caused an AI collapse, unlike a nuclear strike which can be traced.

What are its policy implications?

Risk of Escalation: Using MAIM as a deterrence may justify preemptive strikes or sabotage, increasing chances of conflict. Eg: States might attack suspected AI labs without solid proof, causing diplomatic or military escalation.
False Sense of Security: Assuming AI deterrence works like nuclear deterrence may lead to complacency in governance and oversight. Eg: Policymakers might underinvest in AI safety, believing threat of malfunction is enough to prevent misuse.
Lack of Accountability: Diffuse AI development makes retaliation or regulation difficult, weakening the policy’s enforceability. Eg: If a rogue actor causes an AI incident, it’s hard to trace or penalize, unlike state-driven nuclear attacks.

How feasible is controlling AI chip distribution like nuclear materials?

Different Resource Requirements: Unlike nuclear tech, AI doesn’t need rare or radioactive materials, making chip controls less effective. Eg: Once AI models are trained, they can run on widely available hardware like GPUs.
Widespread Availability: AI chips are mass-produced and used in consumer electronics globally, making strict regulation difficult. Eg: Chips used for gaming or smartphones can also power AI applications.
Black Market and Bypass Risks: Efforts to restrict chip distribution may lead to smuggling or development of alternative supply chains. Eg: Countries barred from chip exports may create domestic chip industries or resort to illegal imports.

What assumptions about AI-powered bioweapons and cyberattacks are speculative, and why?

Inevitability of AI-powered attacks: It’s assumed AI will inevitably be used to develop bioweapons or launch cyberattacks, but such outcomes aren’t guaranteed. Eg: While AI can assist in simulations, creating bioweapons still requires complex biological expertise.
State-driven development dominance: The assumption that states will lead AI weaponization ignores the current dominance of private tech firms. Eg: Companies like OpenAI or Google, not governments, are at the forefront of AI research.
Equating AI with WMDs: Treating AI as a weapon of mass destruction assumes similar scale and impact, which is yet unproven. Eg: Cyberattacks can cause disruption, but rarely match the immediate devastation of a nuclear blast.

Why is more scholarship needed on AI in strategic affairs?

Lack of tailored strategic frameworks: Current strategies often rely on outdated comparisons like nuclear weapons, which don’t suit AI’s complexity. Eg: Using MAD to model AI deterrence ignores AI’s decentralized development and dual-use nature.
Unclear trajectory of AI capabilities: Without deeper research, it’s difficult to predict how AI might evolve or impact global security. Eg: The potential of superintelligent AI remains hypothetical, needing scenario-based academic exploration.
Policy gaps and ethical dilemmas: Scholarly input is crucial to guide regulation and international norms around AI use. Eg: Without academic insight, actions like preemptive strikes on AI labs could escalate conflicts unjustly.

Way forward:

Establish Multilateral AI Governance Frameworks: Nations should collaborate with international organizations, academia, and private stakeholders to create adaptive, inclusive, and enforceable AI governance structures. Eg: A global AI treaty modeled on the Paris Climate Accord can align safety, ethics, and innovation priorities.
Promote Interdisciplinary Strategic Research: Invest in dedicated research centers combining expertise from technology, security studies, ethics, and international law to anticipate and mitigate AI-related risks. Eg: Establishing think tanks like the “AI and National Security Institute” to inform real-time policy with evidence-based analysis.

The conservation argument for resurrecting dire wolf is not credible

Why in the news?

Colossal Biosciences is an American company that combines genetics and conservation in a unique way by bringing back species that have been extinct for thousands of years.

What is the primary goal of Colossal Biosciences’ de-extinction project?

Colossal Biosciences is a biotechnology company specializing in de-extinction projects, aiming to revive extinct species through advanced genetic engineering.

Woolly Mammoth De-Extinction: Colossal is working to resurrect the woolly mammoth by integrating mammoth genes into the Asian elephant genome using CRISPR technology. The goal is to create a cold-resistant elephant with traits characteristic of the woolly mammoth, such as a thick layer of fat and shaggy hair, to inhabit Arctic tundra regions and potentially combat climate change.
Dire Wolf Revival: In a groundbreaking achievement, Colossal announced the birth of three pups—Romulus, Remus, and Khaleesi—genetically engineered to resemble the extinct dire wolf. Using DNA from ancient dire wolf remains, scientists edited the genes of modern gray wolves, resulting in animals that exhibit traits such as larger size and distinctive fur color.

Why do critics question the credibility of reviving extinct species for conservation purposes?

Lack of Scientific Proof: The actual success of reviving extinct species like the woolly mammoth has not yet been proven through rigorous peer review or established results.
Limited Genetic Editing: The extent of genetic editing in revived species often involves only a small number of genes, leading to incomplete or flawed replicas of the original species. Eg: In the case of the dire wolf, only 20 genes were edited, resulting in what critics describe as just a “strange-looking gray wolf” rather than a true de-extinct species.
Ethical Concerns: There are ethical debates over the potential consequences of creating species that may not thrive in the modern environment or might cause unforeseen ecological imbalances. Eg: The introduction of revived species like the woolly mammoth could disrupt current ecosystems in ways that may not be beneficial.

How can bringing back the woolly mammoth help stop global warming?

Restoring Grasslands: The woolly mammoth can help restore Arctic grasslands by grazing on shrubs and plants, which would create open grasslands where permafrost can remain intact. Eg: By grazing, mammoths would prevent the growth of shrubs that trap heat, promoting the return of grasslands that are cooler and better at reflecting sunlight.
Slowing Permafrost Melt: Grasslands absorb less heat than shrub forests, helping to keep the permafrost cool. The return of woolly mammoths could help prevent the thawing of permafrost, which releases methane, a potent greenhouse gas. Eg: Mammoth grazing can keep the ground cooler and slow the thawing of permafrost, thus reducing the release of methane into the atmosphere.
Preventing Methane Emissions: As the permafrost melts, it releases large amounts of methane into the atmosphere. Woolly mammoths could help mitigate this by maintaining ecosystems that slow down the permafrost’s thaw. Eg: With mammoths grazing, the tundra could remain cooler and less prone to releasing methane.
Enhancing Carbon Sequestration: Grasslands are more effective at absorbing carbon than shrubbery or forested areas. By converting tundra back into grasslands, woolly mammoths could enhance carbon sequestration and help store more carbon in the soil. Eg: Woolly mammoths could help re-establish healthy grasslands, which would act as carbon sinks, absorbing more CO2 from the atmosphere.

What is India’s situation in advanced genetic engineering?

Advancements in Agricultural Biotechnology: India has developed a structured regulatory framework for genetically modified organisms (GMOs) under the Environment (Protection) Act, of 1986. Eg: Recently, India initiated trials of CRISPR/Cas9-modified rice varieties in test fields, reflecting a surge in scientific research and innovation in plant genome editing.
Pioneering Genomic Research and Precision Medicine: India’s Genome India Project aims to sequence at least 10,000 Indian genomes to develop predictive diagnostic indicators for various diseases. Eg: Institutions like the Institute of Genomics and Integrative Biology (IGIB) have been instrumental in understanding genetic epidemiology, including the development of the FELUDA COVID-19 test based on CRISPR technology.

Way forward:

Strengthen Ethical and Regulatory Frameworks: India should establish robust regulations and ethical guidelines for genetic engineering, particularly for gene-editing technologies like CRISPR, to ensure safety and sustainability in areas such as agriculture and medicine.
Promote Collaborative Research and Innovation: Encouraging partnerships between academic institutions, the private sector, and the government will help accelerate research and application of advanced genetic technologies, positioning India as a global leader in biotechnology innovation.

Mains PYQ:

[UPSC 2024] What strategies have been developed to prevent such a catastrophe [mass extinction of life]?

Linkage: The article says we should focus more on saving the species that are alive today, rather than trying to bring back extinct ones. The debate about de-extinction raises the question of whether it’s better to spend resources on protecting current species instead.
