At a time when global markets and political leaders are pinning their hopes on Artificial Intelligence (AI) as the deus ex machina that will revitalize the stagnant economies of the West, Nobel laureate economist Christopher Pissarides offers a dose of cold realism. Speaking to Bloomberg, the London School of Economics professor argued that AI, while transformative, will not manage to restore the rapid growth rates experienced by the Western world in previous decades.

The Illusion of Immediate Productivity

Pissarides, renowned for his work on labor economics, points out that there is a significant gap between technological potential and economic reality. While AI can perform tasks with astonishing speed, its integration into the productive fabric of the economy is a slow and arduous process. The history of technological revolutions—from steam to electricity and the internet—shows that it takes decades before innovations translate into measurable GDP growth.

According to the Nobel laureate, the problem lies in the structure of modern Western economies, which are dominated by the service sector. In fields such as healthcare, education, and personal care, human presence remains irreplaceable. AI can assist in data management, but it cannot substitute for the quality of human interaction, which forms the core of value in these sectors. Consequently, productivity gains will be limited and localized in specific pockets of the economy.

Demographic Weight and the Solow Paradox

One of the primary reasons for Pissarides' pessimism is the demographic crisis. The West is aging rapidly, which puts immense pressure on social security systems and reduces the workforce. AI could theoretically fill the gap, but Pissarides argues that the needs of an aging society are such that they require more hands, not necessarily more algorithms.

Furthermore, he indirectly references the famous "Solow Paradox"—the observation that we see computers everywhere except in productivity statistics. AI might make a programmer faster or a lawyer more efficient in research, but if total demand for these services does not increase proportionally, or if the cost of adopting the technology is too high, the net impact on growth remains anemic.

The Need for Structural Reforms

Pissarides emphasizes that focusing on AI as the sole solution is dangerous, as it distracts from necessary structural reforms. Improving infrastructure, reforming the education system, and addressing inequality are equally important for long-term prosperity. Technology is a tool, not a strategy in itself.

In conclusion, Pissarides' warning serves as a call for grounding. The West must learn to live with lower growth rates, focusing more on quality of life and the distribution of wealth produced by technology, rather than the illusory pursuit of the double-digit growth rates of the past. AI will change the world, but it will not automatically save the global economy from its own structural weaknesses.
