The digital economy is often described through software, online platforms, financial applications, and artificial intelligence. Yet every digital service ultimately depends on physical equipment: processors execute instructions, memory stores data, network devices move information, and power systems keep computing infrastructure operating.

This dependence has become increasingly visible as AI investment and demand for computing infrastructure have expanded. The Semiconductor Industry Association (SIA) reported that global semiconductor sales reached $791.7 billion in 2025, up 25.6% from $630.5 billion in 2024. The association attributed much of the industry's growth to strong demand for logic and memory products. [1]

These figures demonstrate the industry's scale, but they should not be confused with the economic value of the entire digital economy. Semiconductor sales measure a particular hardware market, not the total value created by e-commerce, cloud services, financial technology, or software businesses.

The more important question is how dependence on electronic hardware affects economic resilience. A fast processor cannot compensate for an unavailable component, an unreliable electricity supply, or an inadequately secured production system. Similarly, expanding computing capacity creates environmental and infrastructure obligations that do not disappear when a device reaches the end of its useful life.

1. The physical infrastructure behind digital commerce

Digital transactions rely on several interconnected layers of electronics. Processors perform calculations and execute applications; memory and storage retain information; network equipment transfers data; and sensors and controllers connect digital systems to physical operations.

In retail, for example, electronic payment terminals, secure payment components, network connections, and inventory systems help businesses process transactions and coordinate stock. In logistics, radio-frequency identification (RFID), location technologies, and industrial sensors can improve the visibility of goods moving through warehouses and distribution networks.

These examples illustrate how hardware enables a business process; they do not establish that purchasing more advanced equipment automatically increases productivity. Benefits depend on implementation, staff capabilities, system reliability, and whether the organization can use the resulting information to make better decisions.

2. Semiconductor growth does not eliminate supply-chain risk

The semiconductor industry is not a single factory system. It includes chip design, specialized design software, manufacturing equipment, wafer fabrication, materials, assembly, testing, and packaging. Different companies and economies specialize in different stages, and many stages depend on highly specialized inputs.

The Organisation for Economic Co-operation and Development (OECD), in its 2025 policy paper Mapping the Semiconductor Value Chain, identifies geographic concentration, specialization, and cross-border dependencies as important features of the industry. It also highlights the need for better information about specific products and production stages when assessing vulnerabilities. [2]

This distinction matters because the availability of semiconductors in general does not guarantee the availability of a particular chip. A component designed for one application may not be an immediate substitute for another component because of differences in performance, power requirements, interfaces, qualification, or manufacturing processes.

A company may therefore face a production delay even when aggregate semiconductor sales are increasing. Market-wide growth and supply security are different measures: one describes commercial activity, while the other concerns whether a specific component can be obtained in the required quantity, at the required time, and to the required specification.

Why adding suppliers is not enough

Supplier diversification can reduce dependence on a single source, but counting suppliers alone can create a false sense of security. Two suppliers may rely on the same upstream manufacturer, production facility, raw material, or transport route. Their apparent independence may disappear during a common disruption.

A more useful assessment maps critical components to their upstream dependencies. Businesses should identify which parts have long replacement lead times, which alternatives have already been tested, and which production stages are concentrated in a small number of locations. These are practical risk-management recommendations based on the structure described by the OECD, not a claim that every component faces the same level of risk.

3. AI chips connect computing growth to electricity demand

AI systems have increased demand for computing infrastructure, including accelerators, high-bandwidth memory, networking equipment, and data-center facilities. However, the hardware is only one part of the system. Large-scale computing also requires electricity, cooling, physical space, reliable networks, and supporting power equipment.

The International Energy Agency (IEA), in its April 2025 report Energy and AI, estimated that data centers consumed around 415 terawatt-hours (TWh) of electricity in 2024, approximately 1.5% of global electricity consumption. Its base-case outlook projected data-center electricity consumption to reach around 945 TWh by 2030, with AI identified as an important driver of growth. These are model-based estimates and projections, not guaranteed future outcomes. [3]

The economic implication is that computing capacity increasingly depends on the interaction between semiconductor supply and energy infrastructure. A data center may have access to advanced processors yet still face delays if grid connections, transformers, cooling systems, or electricity supply cannot support the planned workload.

Efficiency must also be assessed carefully. A more efficient processor can perform a given task using less energy, but total electricity demand can still increase if the number of tasks, size of models, or scale of deployment grows faster than efficiency improves.

For businesses and policymakers, the relevant question is therefore not simply whether a new chip is faster. It is how much useful work the complete system delivers for its energy, capital, and operating costs.

4. Economic resilience requires targeted risk management

Semiconductor supply risks cannot be eliminated entirely. Manufacturing capacity is expensive, production processes are specialized, and qualification of alternative components can take time. Building additional capacity may improve resilience, but it also involves capital investment, skilled labor, infrastructure, and reliable access to water, energy, materials, and equipment.

The OECD's analysis supports a more targeted approach: understand where dependencies exist, improve information sharing, and evaluate diversification options in light of the characteristics of particular products and production stages. [2]

For an electronics manufacturer, this can translate into several practical steps:

1. Identify critical components. Rank parts according to their importance to production, replacement lead time, and availability of qualified alternatives.
2. Map upstream dependencies. Examine whether different suppliers depend on the same fabrication, packaging, material, or logistics source.
3. Qualify alternatives before a disruption. Test substitute components for compatibility, reliability, safety, and relevant regulatory requirements.
4. Use inventory selectively. Consider strategic buffers for components with high disruption costs and long replenishment times, rather than stockpiling every part indiscriminately.
5. Review recovery arrangements. Establish how production priorities, customer commitments, and communications will be managed during a supply interruption.

The appropriate strategy will vary by industry and company size. A manufacturer producing medical or industrial equipment may face different qualification and continuity requirements from a business assembling consumer accessories. Resilience should be based on the consequences of failure, not on a generic checklist alone.

5. The environmental cost of electronics cannot be ignored

The growth of electronics creates another long-term challenge: what happens to devices after their useful life ends? Electronic waste contains recoverable materials, but it can also contain substances that require appropriate handling. Collection and recycling systems must be able to manage these products safely and recover materials effectively.

The Global E-waste Monitor 2024, produced through collaboration involving the United Nations Institute for Training and Research (UNITAR) and the International Telecommunication Union (ITU), reported that the world generated 62 billion kilograms of electronic waste in 2022. Only 22.3% was documented as formally collected and recycled in an environmentally sound manner. [4]

These figures describe global e-waste, not semiconductor manufacturing waste alone. They nevertheless show why the sustainability of the electronics economy cannot be assessed solely by the energy efficiency of new devices.

Product design, repairability, software support, reuse, take-back programs, and accessible formal collection channels all influence how long devices remain useful and what happens to them afterward. Recycling is important, but it is not a substitute for extending a product's useful life when repair or reuse is safe and practical.

Businesses can begin by tracking the equipment they own, establishing secure data removal procedures before reuse, selecting qualified recycling partners, and documenting the final destination of retired equipment. These steps connect environmental responsibility with information security and asset management.

6. What these trends mean for emerging digital economies

Countries seeking to expand their digital economies do not necessarily need to manufacture every type of semiconductor domestically. The industry's complexity creates opportunities across different activities, including electronic design, embedded software, equipment maintenance, testing, assembly, industrial automation, data-center operations, repair, and recycling.

The relevant opportunity depends on existing capabilities, access to skilled workers, infrastructure quality, market demand, and the cost of entering a particular stage of the value chain. A strategy based on local strengths and realistic demand is more defensible than assuming that building a fabrication plant automatically creates a competitive semiconductor industry.

For emerging digital economies, three priorities deserve attention: developing technical skills, improving reliable power and network infrastructure, and building the institutions needed to support investment, product quality, cybersecurity, and responsible waste management. These priorities are complementary. Hardware investment produces limited economic value if businesses cannot operate it reliably or if the workforce cannot maintain and use it effectively.

Conclusion: resilience is a system-level challenge

Electronics are not merely the physical accessories of the digital economy. They form a critical part of the infrastructure that enables payments, cloud computing, industrial automation, and AI services. Semiconductor market growth demonstrates the scale of demand, while research from the OECD highlights the complexity and geographic dependencies of the industry's supply chain.

At the same time, computing growth depends on energy infrastructure, and the expansion of electronic equipment increases the importance of repair, reuse, and formal recycling. These challenges cannot be solved by faster chips alone.

A more resilient digital economy combines appropriate hardware investment with upstream risk mapping, reliable power, qualified alternatives, skilled workers, sound security practices, and responsible product lifecycle management. The central strategic question is not simply how many electronic devices an economy can deploy, but whether the systems supporting those devices can continue to deliver value when conditions change.
