  • Should generative Artificial Intelligence be regulated?

    Artificial Intelligence

    What’s the news?

    • Generative artificial intelligence (AI) has emerged as a potent force in the digital landscape, raising critical questions about regulation, copyright, and potential risks.

    Central Idea

    • In a remarkably short period, chatbots such as ChatGPT, Bard, Claude, and Pi have demonstrated the remarkable potential of generative AI applications. However, these AI marvels have also exposed their vulnerabilities, prompting policymakers and scientists worldwide to grapple with the question, whether generative AI should be subject to regulation.

    What is generative AI?

    • Like other forms of artificial intelligence, generative AI learns how to take actions based on past data.
    • It creates brand-new content—a text, an image, even computer code—based on that training instead of simply categorizing or identifying data like other AI.
    • The most famous generative AI application is ChatGPT, a chatbot that Microsoft-backed OpenAI released late last year.
    • The AI powering it is known as a large language model because it takes in a text prompt and, from that, writes a human-like response.

    What is the legal framework on which generative AI rests?

    • U.S. Copyright Approach:
      • In the United States, copyright law recognizes only humans as copyright holders.
      • Consequently, AI-generated works often fall outside the scope of copyright protection.
      • This situation poses challenges when it comes to attributing authorship to AI-generated content.
    • India’s Ambiguity:
      • India’s position on AI-generated content and copyright remains ambiguous.
      • A recent case highlights this ambiguity, where a copyright application for an AI-generated work was initially rejected.
      • The lack of clear guidelines in India regarding copyright protection for AI-generated content adds complexity to the legal landscape.

    The European Union’s AI Act

    • Leveling the Playing Field: Recognizing the dominance of large tech corporations in AI development, the Act aims to foster a more competitive environment. This involves measures to reduce the concentration of AI development within a select few companies, promoting innovation and diversity.
    • Transparency Obligations: The AI Act introduces transparency requirements for AI-generated content. Specifically, it mandates the labeling of AI-generated material as such and requires summaries of the training data used. These provisions aim to enhance transparency and accountability in AI systems.

    Contrasting Approaches: Risk-Based vs. Relaxed Regulation

    • EU’s Risk-Based Approach:
      • In contrast, the European Union employs a risk-based approach to AI regulation.
      • This approach involves delineating prohibitions on certain AI practices, recommending ex-ante assessments for others, and enforcing transparency requirements for low-risk AI systems.
      • The EU’s approach acknowledges the multifaceted risks posed by AI and seeks to mitigate them effectively.
    • U.S. Regulatory Approach:
      • The United States maintains a relatively relaxed approach to AI regulation, which may be attributed to underestimating the associated risks or a general reluctance towards extensive regulation.
      • This approach raises concerns, especially in sectors like education, where there is minimal control over the use of generative AI tools by students, including age and content restrictions.
      • Additionally, discussions regarding the regulation of AI risks, particularly in the context of disinformation campaigns and deepfakes, are notably limited in the U.S.

    AI Through an Indian Legal Lens

    • Comprehensive Regulatory Framework: India necessitates a comprehensive regulatory framework that spans both horizontal regulations applicable across sectors and vertical regulations specific to distinct industries. The absence of such regulations results in uncertainties and impediments to effectively addressing AI-related issues.
    • Data Protection Clarity: The Digital Personal Data Protection (DPDP) Act of 2023 plays a pivotal role in addressing data protection concerns. However, the DPDP Act exhibits certain gaps, such as legitimizing data scraping by AI companies when data is publicly available.

    Challenges surrounding trade secrets and transparency in the context of AI

    • Trade Secrets:
    • Corporations frequently employ trade secrets to safeguard their AI models and training data from disclosure.
    • Nevertheless, when AI systems have the potential to cause significant societal harm, there may arise a need to compel companies to divulge these particulars.
    • This predicament raises questions about achieving a balance between safeguarding trade secrets and addressing the broader societal consequences of AI.
    • Transparency:
    • Guaranteeing transparency in AI systems holds paramount importance, particularly when AI-generated content is disseminated.
    • The societal imperative for transparency, particularly in instances where AI-generated content might be exploited for malicious purposes or cause harm,

    Way forward

    • Continued Dialogue: Policymakers, legal experts, industry leaders, and stakeholders should engage in ongoing discussions and collaboration to develop effective regulations and guidelines for generative AI.
    • Ethical Considerations: The development and deployment of AI systems should prioritize ethical principles to ensure responsible use and mitigate potential harms.
    • Transparency and Accountability: There should be efforts to promote transparency in AI systems, especially when AI-generated content is involved. Accountability mechanisms should also be in place to address issues arising from AI use.
    • Comprehensive Regulation: Governments and international bodies may consider developing comprehensive regulatory frameworks that encompass various aspects of AI, including data protection, transparency, accountability, and liability.
    • Public Education: Initiatives to educate the public about AI’s implications, benefits, and limitations should be developed, particularly in sectors where AI is extensively used, such as education.

    Conclusion

    • The global regulation of generative AI emerges as a pressing concern. Adaptive and thoughtful regulatory approaches are essential to address the evolving challenges and opportunities introduced by generative AI on a global scale.

    • India has reached out to Australia in its efforts to procure monoclonal antibody doses for combating the Nipah virus outbreak in Kerala.
    • The monoclonal antibody has successfully passed phase-one trials and has been administered to 14 individuals globally.

    Why use it for Nipah?

    • Currently, there is no effective treatment for Nipah virus infection apart from symptom relief.
    • The virus carries a high mortality rate ranging from 40% to 75%, making it a formidable threat.
    • In comparison, even during the peak of the Covid-19 pandemic, the case fatality ratio (CFR) remained at around three percent.

    What are Monoclonal Antibodies (mAbs)?

    • Monoclonal antibodies (mAbs) are a class of therapeutic proteins that have revolutionized medicine and healthcare.
    • They are used in a wide range of applications, from treating diseases to diagnosing conditions and conducting scientific research.

    Structure of mAbs

    • Monoclonal antibodies are proteins produced by a single type of immune cell, known as a B cell.
    • They are called “monoclonal” because they are derived from a single, cloned parent cell.
    • These antibodies have a specific Y-shaped structure consisting of two identical heavy chains and two identical light chains.
    • The variable region of the antibody binds to a specific antigen with high precision.

    Applications of Monoclonal Antibodies

    • Monoclonal antibodies have a wide range of applications in medicine, science, and diagnostics:
    • MAbs are used to treat various diseases, including cancer, autoimmune disorders, infectious diseases, and more.
    • They are used in diagnostic tests, such as ELISA (enzyme-linked immunosorbent assay), to detect specific molecules like antigens or antibodies.
    • Scientists use mAbs to study and manipulate biological processes. They can be labeled with fluorescent markers for imaging and are crucial tools in cell biology and molecular biology research.
    • Monoclonal antibodies labelled with radioactive isotopes or fluorescent markers can be used for diagnostic imaging techniques like PET (positron emission tomography) scans.
    • They can target specific molecules on cancer cells, minimizing damage to healthy cells during cancer treatment.

    Challenges and Advancements

    • Despite their significant benefits, monoclonal antibodies can have limitations, such as high production costs and the potential for immune responses.
    • Advances in technology, such as the development of humanized antibodies (antibodies with human components to reduce immune reactions), have addressed some of these challenges.
