How does it compare to past transformative GPTs, and how is it already applied in the real world?

What is Generative AI?

Generative AI refers to artificial intelligence systems designed to create content—text, images, videos, music, or even code—by learning from patterns and structures in existing data. This process relies heavily on large, high-quality training datasets and significant computational resources to achieve accuracy and sophistication, making these factors essential components of Generative AI systems. Unlike traditional AI models that analyze patterns or make predictions, Generative AI produces novel outputs. It’s akin to teaching machines to be creative, a skill once thought uniquely human.

At the heart of this technology are advanced neural networks, particularly Generative Adversarial Networks (GANs) and Transformer models. GANs work through a system of competition: a generator creates data while a discriminator evaluates its authenticity. This iterative process allows the generator to improve over time, refining its outputs based on feedback from the discriminator. Transformers, like OpenAI’s GPT, process data sequences to generate coherent and contextually relevant content. These models enable applications ranging from AI-generated art to lifelike voice synthesis and automated software development.

Generative AI as the Next General-Purpose Technology

Economists typically divide technologies into two categories: single-purpose tools and general-purpose technologies (GPTs). While single-purpose tools excel in specific tasks, GPTs—like electricity, the steam engine, or personal computers—revolutionize multiple industries and reshape economies and societies. Generative AI is poised to join this elite group.

Jeffrey Ding, a professor at George Washington University, has documented the transformative impact of past GPTs in his book Technology and the Rise of Great Powers. Drawing on historical case studies of past industrial revolutions and statistical analysis, Ding develops a theory that emphasizes institutional adaptations oriented around diffusing technological advances throughout the economy. His research reveals that the most significant driver of economic growth during these periods was the broad diffusion of GPTs across sectors.

In the digital age, the mechanisms of diffusion have evolved dramatically. Unlike earlier GPTs, which relied heavily on physical infrastructure, Generative AI leverages cloud computing, digital platforms, and global connectivity to achieve widespread adoption. These advancements enable faster scaling across industries while introducing challenges such as ensuring equitable access to resources and addressing digital divides. This new paradigm demands a shift in strategies for promoting diffusion, focusing on accessibility, infrastructure, and digital literacy.

The same principle applies to Generative AI. To reach its full potential, nations and industries must focus on widespread adoption rather than just cutting-edge innovation. This requires strategies that include investment in skills, public trust, and equitable access to AI technologies.
