The McKinsey article explores the evolving role of generative AI (gen AI) from providing information to executing complex workflows as "agents," akin to virtual coworkers. These gen AI-powered agents leverage foundation models to adapt to new scenarios, use natural language for task instructions, and integrate seamlessly with digital ecosystems, potentially automating intricate workflows that previously required human intervention. Early investments by tech giants like Google, Microsoft, and OpenAI signal the rise of agentic systems, which could streamline processes such as loan underwriting, code modernization, and online marketing. However, the technology remains nascent, warranting careful strategic planning and human oversight to mitigate risks and maximize its potential in business applications.
