For two centuries, the guiding principle of global economic participation was based on comparative advantage. A country didn’t have to excel at everything; it just needed to be relatively better at certain goods or services. Whether it was cotton, copper, coffee or code, whatever a nation could produce at a lower relative cost became its entry point into international trade. This framework was simple, intentionally inclusive and provided even the poorest economies with a viable route to growth through specialization and commerce.
That framework is now collapsing, not gradually or partially, but in a structural and possibly irreversible way. The cause is artificial intelligence (AI).
AI is a general-purpose technology that transforms how countries trade, shifting advantage from labor, resources and manufacturing scale to data ecosystems, digital infrastructure, algorithms and regulation. This algorithmic comparative advantage is rapidly concentrating among already dominant economies.
For developing nations, this is more than simply an inconvenience; it represents a serious economic threat to their survival.
The old ladder is being pulled up
The development trajectory of the twentieth century followed a clear pattern. Countries started with agriculture and raw material exports, built up their capital, transitioned into light manufacturing, advanced to higher-value industrial output, and ultimately developed service sectors. Nations like South Korea and China successfully navigated this progression. Although challenging, the pathway was achievable.
AI is dismantling that ladder level by level
The first level, low-cost labor, is fading due to automation. Robotic systems and AI-powered production lines allow companies to produce closer to their markets rather than offshoring to lower-cost regions. As automation replaces work previously done in countries like Bangladesh and Vietnam, wage disparities narrow. When algorithms manage supply chains, quality control and logistics without human intervention, the benefit of cheap, plentiful labor disappears.
The second level, focused on manufactured exports, is evolving through additive manufacturing. 3D printing shifts the advantage from physical assembly to design files, specialized materials and certification, elements that are uncommon in developing countries. Local printing based on digital blueprints often offers little value; the true asset lies in the algorithm, not in physical assembly.
The third level, services, is now being overtaken by AI before most developing economies can access it. Tasks such as call center operations, data entry, and basic legal, accounting and medical transcription, which were key to the early service export booms in India, the Philippines and Kenya, are routine functions rapidly automated by AI systems.
The ladder isn’t merely becoming more difficult to climb; for many nations, it’s disappearing altogether.
The infrastructure gap is now a comparative advantage gap
Behind every advanced AI system lies an infrastructure stack that many developing nations lack, including data centers, high-speed internet, cloud platforms, proprietary datasets, and skilled talent. These are essential foundations for an algorithmic edge; the 21st-century equivalent of land, labour and capital.
High-income economies are expected to dominate AI-driven income growth over the next decade, while low-income economies, lacking digital infrastructure and skilled workforces, will see modest gains that may be offset by displacement in labor-intensive sectors.
This asymmetry isn’t a market failure but a structural feature of algorithmic advantage, in which data creates models, models generate insights, and insights drive revenue, fueling more data and compute. This cycle rewards early and well-resourced entrants, raising barriers to entry for economies outside it.
At the same time, the governance frameworks surrounding AI may deepen existing divides. Meeting strict AI regulations requires advanced legal, technical, and institutional resources that many developing countries currently lack. Without coordinated international assistance, well-intentioned safety regulations could inadvertently create non-tariff barriers, preventing firms from developing countries from accessing major markets, not because their products are unsafe, but because they lack the resources to demonstrate compliance. In fact, regulatory capacity is increasingly a form of comparative advantage, with its distribution as uneven as that of compute resources and data.
Sovereign AI and the closing window
The world’s leading economies are pursuing ‘sovereign AI’ strategies, state-led efforts to control data, supply chains, models and regulations that shape competitive advantage.
This can be seen as a modern version of mercantilism. Instead of hoarding gold or supporting nascent industries, 21st-century digital mercantilists amass data, subsidize computing infrastructure, and protect their leading AI companies from foreign rivals. They also forge geopolitical alliances, techno-blocs that control access to the most advanced AI systems and determine the conditions.
For developing nations, these techno-blocs signal a narrowing window. As the US and China manage advanced semiconductors, providers limit API access for geopolitical reasons, and digital trade agreements favor dominant economies, opportunities for developing nations to access algorithmic infrastructure are becoming more limited rather than more open.
The African Union’s AI Strategy aims to coordinate resources and data governance, and to align AI with development goals such as the African Continental Free Trade Area. However, strategies can’t replace essential compute infrastructure, proprietary data, and frontier models needed for comparative advantage. A good strategy without infrastructure is like a map without a road.
What must change
AI governance as a global general-purpose technology cannot rely solely on market forces, nor should it be shaped only by the leading economies. Urgently, three reforms are necessary.
First, the WTO’s digital trade framework should actively involve developing nations and address structural asymmetries, such as access to AI infrastructure, compute, data and models, beyond commercial concerns. Progress has been made in regulating customs duties on electronic transmissions and data localization, but more is needed to treat AI access as a development issue.
Second, international institutions should prioritize investing in ‘algorithmic infrastructure developmental assistance.’ Like previous initiatives, which recognized physical infrastructure, roads, ports and electricity, today’s strategies must also value data centers, connectivity, AI talent pipelines, and regulatory capacity as crucial for competitive advantage. Ignoring this shift risks planning for an outdated world.
Third, trade agreements should include provisions on source code and algorithmic transparency. Rules that prevent AI systems from being scrutinized restrict governments’ capacity, especially in developing countries, to evaluate, audit, and challenge AI systems operating within their jurisdictions. This often benefits dominant firms at the cost of these nations’ regulatory authority.
The wealth of nations, rewritten
David Ricardo’s insight was that trade, based on comparative advantage, could be a positive-sum game in which specialization and exchange could simultaneously benefit all participating nations. This remains a compelling and morally persuasive vision. However, it was based on a world in which comparative advantage was determined by geography, demography, and endowments. Algorithmic comparative advantage does not simply diffuse across many nations but tends to concentrate in a few countries. Instead, it accumulates and intensifies. Currently, it is being exploited, regulated, and safeguarded by those who already hold the lead.
The international community should establish AI infrastructure, governance, and access terms that provide developing nations with a genuine path to participation. This will prevent the AI revolution from leaving many nations behind as they navigate an increasingly complex AI landscape.
In the twenty-first century, a country’s wealth is measured by petabytes and petaflops. The key question now isn’t about which nation is the most efficient producer, but about which has access to the algorithm economy.
