Four Years After the Brookings Prediction: Has the Fourth Industrial Revolution Transformed Africa?

In January 2020, the Brookings Institution published a landmark article by economists Njuguna Ndung’u and Landry Signé, arguing that the Fourth Industrial Revolution Africa was poised to turn the continent into a global powerhouse. The thesis was bold: with high mobile penetration, a young population, and a willingness to leapfrog legacy infrastructure, Africa could bypass the industrial age and emerge as a digital leader. Four years later—after a pandemic, supply chain shocks, and a surge in global tech investment—the question demands an evidence-based answer. Has the digital transformation Africa predicted by the Brookings article materialized, or has the promise remained largely aspirational?

This article revisits the original forecast, tracking progress across connectivity, fintech, policy, and investment. Drawing on data from the GSMA, International Telecommunication Union (ITU), World Bank, and African tech ecosystem reports, we assess whether Africa is on track to realize its digital destiny—or whether structural gaps remain too wide to close.

The 2020 Vision: A Bold Prediction

Ndung’u and Signé’s argument rested on three pillars: demographic dividend (60% of the population under 25), rapid mobile phone adoption (already over 500 million subscribers in 2019), and a proven track record of leapfrogging—most notably in mobile money, where fintech Africa had already bypassed traditional banking. They predicted that the Fourth Industrial Revolution (4IR)—embodied by artificial intelligence, the Internet of Things, blockchain, and 3D printing—would enable Africa to “create new markets, increase productivity, and expand opportunities for millions.”

The timing was critical. Published in January 2020, the piece captured the pre-pandemic optimism. Africa had just launched the African Continental Free Trade Area (AfCFTA), foreign direct investment was rising, and tech hubs from Nairobi to Lagos were attracting global attention. The authors, both seasoned African economic policy experts—Ndung’u served as governor of the Central Bank of Kenya and Signé as a senior fellow at Brookings—lent the prediction considerable credibility.

Yet the article also acknowledged barriers: poor infrastructure, skill shortages, and governance risks. The question was whether these would be resolved quickly enough for the digital transformation to take hold.

Reality Check: What Actually Happened?

Four years on, the data presents a mixed picture of digitization in Africa. On the positive side, internet penetration has grown from roughly 28% in 2019 to over 36% by early 2024, according to the ITU. Mobile internet users increased by nearly 100 million, reaching 480 million. But that still leaves over 700 million Africans offline—a stark reminder of the digital divide Africa faces.

Mobile money, the poster child of African leapfrogging, continued its meteoric rise. GSMA data shows that mobile money transactions in sub-Saharan Africa reached $850 billion in 2023, up from $490 billion in 2019. In countries like Kenya, Ghana, and Uganda, mobile money accounts now outnumber bank accounts. The COVID-19 pandemic acted as an unexpected accelerator: contactless payments, digital remittances, and online commerce surged as lockdowns forced people to transact remotely.

However, the pandemic also exposed deep fault lines. While urban professionals shifted to Zoom and e-commerce, rural communities—lacking both internet connectivity and digital literacy—were left further behind. The gender gap in mobile internet usage widened: women in sub-Saharan Africa are now 37% less likely than men to use mobile internet, a gap that has grown since 2020.

Infrastructure projects have brought hope. The 2Africa undersea cable, which will circle the continent with 45,000 kilometers of fiber, is on track to land in 33 countries by 2025. Starlink, Elon Musk’s satellite internet service, launched in Nigeria, Rwanda, and Kenya, offering speeds that could transform remote areas. But high costs—Starlink’s hardware kit costs $600 in Kenya—and regulatory hurdles limit adoption. As one analyst put it, “The cable is laid, but the last mile remains a dirt road.”

Sectoral Deep Dive: Where Leapfrogging Worked and Where It Didn’t

Fintech: The Unqualified Success

Fintech remains the clearest example of the Fourth Industrial Revolution Africa taking hold. Nigerian unicorns Flutterwave and Paystack (acquired by Stripe in 2020 for $200 million) have built payment rails that serve millions of merchants and consumers. M-Pesa in East Africa evolved from a simple money-transfer service to a full-fledged financial platform offering loans, savings, and insurance. By 2023, the African tech ecosystem had produced seven fintech unicorns, and venture capital flows into fintech accounted for over 40% of all African tech funding.

The impact on financial inclusion is measurable: the share of adults with an account at a financial institution or mobile money provider rose from 43% in 2017 to 55% in 2021 (World Bank Global Findex), and early data suggests further gains by 2024. This is leapfrogging in action—millions of Africans skipped bank branches entirely, moving from cash to mobile wallets.

AgriTech and HealthTech: Slow but Emerging

Agriculture employs roughly 60% of Africa’s workforce, yet agritech adoption has been sluggish. Startups like Twiga Foods in Kenya and Apollo Agriculture in Zambia use mobile platforms to connect farmers with markets, inputs, and credit, but scalability is hampered by poor road networks, low smartphone penetration, and limited digital literacy among older farmers. A 2023 report by the African Development Bank noted that only 2% of smallholder farmers use digital tools for crop management.

Healthtech saw a pandemic-driven boost. Telemedicine platforms such as India-based Practo (operating in Kenya) and homegrown solutions like Nigeria’s Helium Health experienced surges in usage. However, regulatory fragmentation, unreliable electricity, and low internet bandwidth in rural clinics have prevented widespread adoption. The 4IR promise of “democratized access” to healthcare remains largely aspirational outside major cities.

Education and Remote Work: The Great Unevenness

During COVID-19, governments scrambled to move education online, but the results exposed the digital divide. UNESCO estimated that in sub-Saharan Africa, only 25% of students could access remote learning during school closures. Four years later, e-learning platforms like Eneza Education (used by 6 million students in Kenya, Ghana, and Côte d’Ivoire) have grown, but the quality gap persists. Meanwhile, remote work—a hallmark of 4IR—became a reality for African professionals in tech and services, but largely bypassed the informal sector, which employs 85% of the workforce.

Policy and Investment: The Hidden Hand

The policy environment has evolved significantly since 2020. The African Continental Free Trade Area (AfCFTA) entered its implementation phase, and in 2023 member states agreed on a Digital Trade Protocol aimed at harmonizing data governance, e-commerce rules, and digital payments across the continent. National digital strategies, such as Kenya’s “Digital Economy Blueprint” and Rwanda’s “Smart Rwanda Master Plan,” have attracted investment and created regulatory clarity.

On the investment front, venture capital into African tech ecosystem startups reached a record $5.2 billion in 2021, then declined to $2.9 billion in 2023 amid a global funding winter—still double the 2019 level. Major deals included Safaricom’s $1.2 billion investment in Ethiopian telecom infrastructure and Microsoft’s $1 billion data center expansion in South Africa. China, the United Arab Emirates, and US tech giants (Amazon, Google, Meta) have all laid undersea cables and built data centers.

Yet policy inconsistency remains a barrier. Nigeria’s 2023 currency redesign and cash scarcity, coupled with a 10% tax on digital transactions, rattled fintech companies. Ethiopia’s telecom liberalization, though promising, has been slow to open fully. Several countries have introduced restrictive data localization laws, while others—like South Africa and Kenya—offer more business-friendly regimes.

The World Bank’s 2023 “Digital Africa” report identifies governance as the single biggest risk: “Without predictable regulations, digital infrastructure investment will stall, and the digital divide will widen.”

The Verdict: Powerhouse in the Making or Hype?

Four years after the Brookings prediction, the answer is neither a triumphant yes nor a dismissive no. Africa has made real progress in digitization, particularly in mobile money and fintech. The continent now accounts for 70% of the world’s mobile money transactions. Tech hubs in Nairobi, Lagos, Cape Town, and Accra are generating globally competitive startups. Policy frameworks are maturing, and infrastructure—both undersea cables and satellite internet—is improving.

But the vision of Africa as a global powerhouse—one that leads in AI development, industrial automation, and digital manufacturing—remains distant. Key obstacles persist:

• Infrastructure deficits: Only 36% internet penetration, unreliable electricity in many regions.
• Digital skills gap: UNESCO estimates that 10 million African children are at risk of dropping out of school annually due to lack of digital access.
• Gender and rural divides: Women and rural populations are systematically excluded.
• Policy instability: Taxes, tariffs, and regulatory changes discourage long-term investment.

The biggest lesson from the original Brookings thesis is that leapfrogging is not automatic. It requires deliberate public-private partnerships, sustained investment in education, and political will to ensure that the digital tide lifts all boats—not just those in tech hubs.

For policymakers, the priority should be last-mile connectivity and digital literacy. For investors, opportunities remain vast in fintech, energy tech, and logistics, but due diligence on regulatory environments is essential. For the African diaspora and global development institutions, the fourth industrial revolution offers a chance to close the gap—but only if the foundations are laid now.

The fourth industrial revolution has not transformed Africa—yet. But the seeds are planted. Whether they will grow into a powerhouse depends not on technology, but on the choices made in the next four years.
