South Africa’s private surveillance machine is fueling a digital apartheid
Johannesburg, the sprawling megacity once home to Nelson Mandela and Desmond Tutu, is now birthing a uniquely South African surveillance model. In the last five years, the city has become host to a centralized, coordinated, entirely privatized mass surveillance operation. Vumacam, the company building the nationwide CCTV network, already has over 6,600 cameras and counting, more than 5,000 of which are concentrated in Johannesburg. The video footage it takes feeds into security rooms around the country, which then use all manner of AI tools like license plate recognition to track population movement and trace individuals. These tools have been enthusiastically adopted by the local security industry, grappling with the pressures of a high-crime environment.
Civil rights activists worry the new surveillance is fueling a digital apartheid and unraveling people’s democratic liberties, but a growing chorus of experts say the stakes are even higher. They argue that the impact of artificial intelligence is repeating the patterns of colonial history, and here in South Africa, where colonial legacies abound, the unfettered deployment of AI surveillance offers just one case study in how a technology that promised to bring societies into the future is threatening to send them back to the past.

This is the first part of our series on AI colonialism, digging into how the technology is impoverishing the communities and countries that don’t have a say in its development. Parts 2—4 are coming later in the week, and you can read Karen Hao’s introductory essay here.
How we can fix AI’s inequality problem
The economy is being transformed by digital technologies, especially in artificial intelligence, that are rapidly changing how we live and work. But this transformation poses a troubling puzzle: these technologies haven’t done much to grow the economy, and income inequality is worsening. Productivity growth, which economists consider essential to improving living standards, has largely been sluggish since at least the mid-2000s in many countries.
Why are these technologies failing to produce more economic growth? Why aren’t they fueling more widespread prosperity? To find an answer, some leading economists and policy experts are looking more closely at how we invent and deploy AI and automation—and identifying ways we can make better choices.

Aging clocks aim to predict how long you’ll live
Age is much more than the number of birthdays you’ve clocked. Stress, sleep, and diet all influence how our organs cope with the wear and tear of everyday life, which could make you age faster or slower than people born on the same day. That means your biological age could be quite different from your chronological age—the number of years you’ve been alive.
Your biological age is likely a better reflection of your physical health and even your own mortality than your chronological age. But calculating it isn’t nearly as straightforward, which is why scientists have spent the last decade developing tools called aging clocks that assess markers in your body to reveal your biological age and predict how many healthy years you have left. Proponents of aging clocks are already trying to use them to show that anti-aging interventions can make individuals biologically younger. But it’s unclear that they’re accurate or reliable enough to make such claims. Read the full story.
