Agentic AI: Who Is Responsible When AI Acts for You?

The email sat in my drafts folder for twenty minutes while I debated whether to send it. I had asked an AI assistant to write a message to my professor requesting an extension on my research paper, and it came back polite and professional, better than anything I would have typed at midnight. But as my cursor hovered over the send button, a question stopped me: if this message somehow offended her or violated some policy I had missed, whose fault would that be? I pressed send anyway, got my extension, and forgot about the incident until my computer science seminar introduced the concept of agentic AI.

Unlike tools that wait for commands, agentic systems make decisions and take actions with minimal human oversight, from scheduling meetings to trading stocks to managing customer complaints. As these systems gain more autonomy, the old rules about accountability start to break down. When an AI acts on your behalf and something goes wrong, responsibility becomes a tangled question involving the user who deployed it, the company that built it, and the machine itself.

I first encountered true agentic AI last semester when my roommate started using a personal assistant program that did not just remind him of deadlines but actually rescheduled his appointments when conflicts arose. It would scan his calendar, email his study group to propose new times, and confirm changes without asking him first. He loved the convenience until it moved an important meeting with his advisor to a time when he had class, and he missed the rescheduled slot entirely. That incident taught me the difference between a passive tool and an active agent. Traditional software executes the exact instructions you give it, like a calculator that only answers when you press buttons. Agentic AI interprets your goals and decides how to achieve them, making choices you never explicitly approved. The technology relies on large language models and decision-making algorithms that predict what you want based on past behavior and stated preferences. This autonomy makes the systems useful but also unpredictable, because they operate in the gap between your intention and their interpretation of it.

The most obvious place to assign responsibility is to the person who deployed the AI, and in many cases that makes sense. When I used that email assistant, I chose to trust its output and click send, so any consequences should fall on me. I could have edited the message or written my own from scratch. This reasoning follows centuries of legal tradition holding people accountable for the tools they use, whether that tool is a hammer or a search engine. If I hire a human assistant and they make a mistake while following my general instructions, I still bear responsibility for putting them in that position. The same logic should apply to AI assistants that act under my authority. My marketing professor made this point during a class discussion, arguing that convenience does not erase accountability. If a business uses an AI chatbot that insults a customer or leaks private information, the business cannot simply blame the algorithm and walk away. They chose to deploy that system, they benefited from its efficiency, and they should answer for its failures.

Yet this user-focused accountability breaks down when the AI operates with genuine independence. Consider the autonomous trading programs that execute millions of transactions per second based on market patterns no human explicitly programmed them to recognize. In 2010, such systems caused the Flash Crash, erasing nearly a trillion dollars in market value in minutes before recovering. No single trader intended that outcome or could have predicted the cascade of algorithmic decisions that produced it. Holding individual users responsible in such cases feels absurd because the harm emerged from the interaction of multiple agents making choices faster than humans can monitor. My economics professor described this as a problem of emergent behavior, where complex systems produce results that none of their components intended. When an AI assistant books a flight on your behalf and later cancels it due to a mistaken interpretation of an ambiguous email, you might fairly claim you never authorized that cancellation. The more autonomous these systems become, the wider the gap grows between what you intended and what the AI decided to do in your name.

This gap pushes responsibility toward the companies that design and deploy agentic systems. They choose how much autonomy to grant their AI, what guardrails to install, and what risks to accept in pursuit of efficiency. A developer who builds a medical AI that adjusts drug dosages without requiring human confirmation has made a choice about acceptable risk, and they should bear responsibility when that choice leads to harm. After all, these companies profit from selling AI agents precisely because those agents reduce the need for human labor and oversight. Some legal scholars argue for treating AI developers like manufacturers of physical products, who face strict liability if their products injure someone regardless of whether the company was negligent. Under this framework, if your AI assistant defames someone in an email it composed, the company behind that assistant should compensate the victim, just as a car manufacturer pays when faulty brakes cause an accident. This approach protects users and victims while incentivizing companies to build safer systems. It also acknowledges that most users lack the technical knowledge to evaluate how an AI makes decisions or what risks it might create.

The question grows even murkier when we consider whether an AI agent itself might bear some form of responsibility. Most legal systems grant responsibility only to entities that have intentions, consciousness, or the capacity to understand right and wrong, which current AI clearly lacks. These systems do not want anything or feel regret or learn moral lessons from their mistakes. They optimize for objectives we define, without understanding the meaning or consequences of their actions. My philosophy professor argues that calling an AI responsible would be like blaming a river for flooding, a category error that confuses causes with moral agents. Yet some technologists predict that future AI systems might develop enough sophistication to warrant a new legal status, perhaps similar to how corporations are treated as legal persons for some purposes. If an AI truly made independent choices based on its own reasoning, holding it accountable might make more sense than blaming a user who no longer controls it or a developer who built it years earlier. For now, though, that possibility remains speculative, and existing AI agents remain tools, however autonomous they appear.

I still use AI assistants for drafting emails and organizing my schedule, but I edit everything before it goes out and double-check decisions that matter. That caution comes from recognizing that responsibility has not actually shifted to the machine or vanished into some legal gray zone. When my AI assistant acts on my behalf, I act through it, accepting both the convenience and the risk. At the same time, I have started paying attention to which companies I trust with that authority, avoiding services that prioritize speed over safety or that make accountability deliberately unclear. The question of responsibility will only grow more urgent as these systems become more capable and more widely deployed. Perhaps the answer is not to choose one party to blame but to recognize that responsibility must be shared and specific to context: users accountable for decisions they could reasonably oversee, companies liable for risks they knowingly create, and legal systems flexible enough to assign fault without paralyzing innovation. What troubles me most is not any single answer but the possibility that we will drift into an age of powerful autonomous agents without ever clearly deciding who answers when something goes wrong.
