- Jean Pisani-Ferry warns against massive investments and the possibility that these actions are more a matter of speculation than a robust development strategy. The dominant role of the « Magnificent Seven » and the concentration of investments in the construction of colossal data centers demonstrate the polarization of this sector.
- While Europe is also exposed to these risks through its savings, it must critically assess its role and strategies in the global AI landscape. The current stagnation of European productivity reveals an urgent need for policymakers and economists, such as Jean Pisani-Ferry, to rethink how Europe can leverage AI while minimizing the risks of potential collapse.
Jean Pisani-Ferry, a renowned economist, poses a crucial question on the current economic scene: Is artificial intelligence the engine of sustainable growth, or is it merely a speculative bubble? While massive investments are being concentrated in this field, opinions differ regarding its true economic impact. At the heart of this debate, Europe, exposed through its savings, finds itself at a turning point where productivity is stagnating, while the United States is experiencing growth fueled by AI. The question remains open, requiring rigorous analysis to better understand the future implications of this revolutionary technology. The question of whether artificial intelligence (AI) represents an engine of sustainable growth or a speculative bubble is at the heart of a complex and unavoidable debate. Economist Jean Pisani-Ferry sheds light on the massive investments made in the field of AI, while also highlighting the potential risks they represent. This article explores the economic implications of AI, the rapid growth of its users worldwide, and the associated investment trends.The Evolution of Artificial Intelligence and Its Global Impact Artificial intelligence is undeniably transforming professional and personal practices around the world. With ChatGPT, which reached 800 million active users just three years after its launch, demonstrating that AI is already shaping the social and economic fabric. Compared to other platforms like TikTok and WhatsApp, the rise of AI is meteoric, and its potential seems limitless. An Unprecedented Wave of Investments The United States is experiencing growth fueled primarily by investments in AI. Since the beginning of 2025, almost all of this growth has come from this sector, contributing nearly half a percentage point annually. The Bank of France points out that this situation is partly responsible for the stagnation of productivity in Europe, where competitiveness is struggling to keep pace with the US. According to Goldman Sachs forecasts, capital expenditures for the current year will exceed $500 billion. This level of investment is comparable to that seen during the major booms of past decades, although it is focused almost exclusively on AI companies themselves. Risks and uncertainties related to a potential bubble
What distinguishes the current wave of investment from previous ones, such as the dot-com bubble, is that AI companies, such as Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla, dominate the landscape. User sectors, such as financial and communication services, appear to play a secondary role compared to the capital expenditures of AI giants. This situation generates considerable uncertainty about the sustainability of this economic dynamic.

Europe faces the AI challenge.
While Europe is also exposed to these risks through its savings, it must critically assess its role and strategies in the global AI landscape. The current stagnation of European productivity reveals an urgent need for policymakers and economists, such as Jean Pisani-Ferry, to rethink how Europe can leverage AI while minimizing the risks of potential collapse.
