The Doctrine That Once Shielded Medical Manufacturers # For decades, the learned intermediary doctrine provided pharmaceutical and medical device manufacturers with a powerful liability shield. The principle was elegant: manufacturers need not warn patients directly because physicians, as “learned intermediaries”, stand between manufacturer and patient. Warn the doctor adequately, and the duty to warn is satisfied.
The End of Platform Immunity for AI # For three decades, Section 230 of the Communications Decency Act shielded online platforms from liability for user-generated content. That shield is crumbling. Courts now distinguish between passively hosting third-party content, still protected, and actively generating, amplifying, or curating content through AI systems, increasingly not protected.
AI Companions: From Emotional Support to Legal Reckoning # AI companion chatbots, designed for emotional connection, romantic relationships, and mental health support, have become a distinct category of liability concern separate from customer service chatbots. These applications are marketed to lonely, depressed, and vulnerable users seeking human-like connection. When those users include children and teenagers struggling with mental health, the stakes become deadly.
The Youth Mental Health Crisis Meets Product Liability # Social media platforms face a historic legal reckoning. Thousands of lawsuits allege that platforms’ algorithmic design intentionally maximizes engagement at the cost of children’s mental health, driving addiction, anxiety, depression, eating disorders, and suicide. Courts are increasingly willing to treat recommendation algorithms as products subject to liability, rather than neutral conduits protected by Section 230.
The Paradigm Shift # For decades, software developers enjoyed a shield that manufacturers of physical products never had: software was generally not considered a “product” subject to strict liability under U.S. law. If software caused harm, plaintiffs typically had to prove negligence, that the developer failed to exercise reasonable care.
AI Chatbots: From Convenience to Liability # Customer-facing AI chatbots have moved from novelty to necessity across industries. Companies deploy these systems for 24/7 customer support, sales assistance, and information delivery. But as chatbots become more sophisticatedand more trusted by consumersthe legal exposure for their failures has grown dramatically.
AI in Drug Discovery: The New Liability Frontier # Artificial intelligence is transforming pharmaceutical development at unprecedented scale. The AI drug discovery market has grown to approximately $2.5-7 billion in 2025, with projections reaching $16-134 billion by 2034 depending on the analysis. AI-discovered molecules reportedly achieve an 80-90% success rate in Phase I trials, substantially higher than traditional discovery methods.
The Autonomous Agent Challenge # AI systems are evolving from tools that respond to prompts into agents that act autonomously. These “agentic” AI systems can browse the web, execute code, manage files, schedule appointments, negotiate purchases, and even enter contracts, all without human intervention at each step.
The Autonomous Vehicle Liability Reckoning # Autonomous vehicle technology promised to eliminate human error, responsible for over 90% of crashes. Instead, a new category of liability has emerged: algorithmic negligence, where AI systems make fatal errors that cannot be easily explained, predicted, or prevented. As self-driving technology scales from test fleets to consumer vehicles, courts are grappling with fundamental questions: Who bears responsibility when software kills? What disclosure duties exist for AI limitations? And does the promise of autonomy shift liability from driver to manufacturer?
The Autonomous Vehicle Liability Crisis # Self-driving cars were promised to eliminate human error and make roads safer. Instead, they have created a complex liability landscape where crashes, injuries, and deaths have triggered hundreds of lawsuits, billions in regulatory penalties, and fundamental questions about who bears responsibility when AI-controlled vehicles cause harm.
Executive Summary # AI medical devices are proliferating faster than regulatory infrastructure can track their failures. With over 1,200 FDA-authorized AI devices and a 14% increase in AI-related malpractice claims since 2022, understanding the liability landscape has never been more critical.
The AI Litigation Explosion # Artificial intelligence litigation has reached an inflection point. From copyright battles over training data to employment discrimination class actions, from product liability claims for AI chatbots to healthcare AI denial lawsuits, 2025 has seen an unprecedented wave of cases that will define AI accountability for decades to come.
