In June 2024, first-year senior secondary students from nine public schools in Benin City, Nigeria, stayed after class to study English with a machine.2 Floods in the rainy season, teacher strikes and after-school jobs broke their attendance.1 Microsoft Copilot, running on GPT-4, waited on every screen and answered whatever each student typed. One student, Omorogbe Uyiosa of Edo Boys High School, called the tool a tutor that takes any shape, “depending on the prompt you write.”1
After six weeks, a pen-and-paper test showed gains of about 0.3 standard deviations, which World Bank researchers equate to almost two years of typical learning.1,2 Against a database of randomized trials in developing countries, the program outperformed four in five education interventions. Girls, who started behind the boys, posted the largest gains.1,2
Uyi’s six words carry the central bargain of this age: the machine answers anyone, and the prompt decides what each person carries home. For three decades I reported the news after it happened, in newspapers and on television in Guyana and Canada. Today I report on a future that can still break two ways.
Machine intelligence opens a new era of human flourishing. Cost, skill and habit hold billions of people in a no man’s land between an old world of reaction and a new world of authorship. Global leaders can lay boards across that mud, and they must start with schools.
01The evidence for flourishing
Benin City joins a growing file of measured gains. Economists Erik Brynjolfsson, Danielle Li and Lindsey Raymond tracked 5,179 customer support agents as their employer rolled out a generative AI assistant. Agents resolved 14 percent more issues per hour on average, and the novice and low-skilled among them gained 34 percent.3 The authors found suggestive evidence that the assistant carried the best agents’ practices to the newest hires.3
At Harvard, lecturers Greg Kestin and Kelly Miller and their colleagues built an AI tutor on research-based teaching principles and tested it against active learning led by experienced instructors. In a randomized trial with 194 physics students, learners gained more than twice as much from the tutor, in a median of 49 minutes against a 60-minute class.4
In Toronto, St. Michael’s Hospital runs CHARTWatch, a system that reads patient data such as blood pressure and heart rate. It warns nurses and doctors hours before a patient slides toward crisis. A study in the Canadian Medical Association Journal found that unexpected deaths on the ward fell 26 percent after the system’s launch.5
Demis Hassabis, who shared the 2024 Nobel Prize in Chemistry for AI that predicts protein structures, sized the coming change for The Guardian: “10 times bigger than the Industrial Revolution.”6,7 Microsoft counts more than 1.2 billion people who picked up AI tools in under three years, a pace that beat the internet, the personal computer and the smartphone.8
Anyone with a connection can now call a tutor, a researcher, an editor and a programmer into one conversation. An idea that once waited years for a firm or a grant can now reach a working draft before lunch. The promise rests on measurement, and the measurements keep arriving.
02Same machine, split outcomes
Kenya supplies harder evidence, from a five-month field experiment that researchers at Harvard Business School and the University of California, Berkeley ran with 640 Kenyan entrepreneurs. A random draw gave some of them a GPT-4 business mentor on WhatsApp.9 Across the whole group, revenues and profits showed no clear average effect, yet beneath that average the owners split. By the researchers’ estimate, high performers gained more than 15 percent, while low performers did almost 10 percent worse than owners without the mentor.9
The split came neither from the questions the owners asked nor from the advice they received. It came from which advice each owner chose and how each one put it to work.9 Strong performers used the mentor to find tailored fixes, such as another source of power during blackouts and a new car-wash detergent in demand. Weaker performers leaned toward generic moves such as cutting prices and buying ads.9
A team led by Harvard Business School researchers ran a sharper test with 758 consultants at Boston Consulting Group. On 18 realistic tasks inside the machine’s abilities, consultants using GPT-4 finished 12.2 percent more work, 25.1 percent faster, at more than 40 percent higher quality. Below-average consultants gained 43 percent against 17 percent for stronger peers.10 The researchers then picked a task just outside the machine’s reach. Consultants using AI reached the correct answer 19 percentage points less often than consultants who worked without the machine.10
The authors call that boundary a “jagged technological frontier,” because two tasks of similar difficulty can fall on opposite sides of the line. Elite professionals followed the machine past that line.
The same split runs across the planet. In early 2026, Microsoft’s AI Economy Institute found generative AI in use among 27.5 percent of working-age people in the Global North. The Global South reached 15.4 percent, while adoption in the North grew more than twice as fast as adoption in the South.11 The International Telecommunication Union counts 2.2 billion people without the internet. In high-income countries, 94 percent of people use the internet, against 23 percent in low-income countries.12
Kristalina Georgieva, the IMF’s managing director, introduced the Fund’s 2024 analysis of AI and jobs with a warning: “In most scenarios, AI will likely worsen overall inequality.”13 Even Sam Altman, whose company built ChatGPT, warned in 2024 that without enough infrastructure AI could turn into “mostly a tool for rich people.”14
Carry that logic forward ten years. The machine answers every caller, but people who already ask well pull ahead each quarter. People who never learned to ask fall further behind with every unchecked answer they accept. Habit alone builds that default future.
03No man’s land

On 29 October 1917, near Hooge in the Ypres salient, a camera caught Australian artillerymen walking single file on a duckboard track through the shattered trees of Chateau Wood. The photograph carries Frank Hurley’s name, though historians now debate who pressed the shutter, and on which day.28 Duckboards laid safe footing across ground that shellfire churned into mud. Between the opposing trenches of that war lay no man’s land, ground neither army could hold.
Billions of people now stand in a no man’s land of a different kind. Behind them lies an old trench of habit, a life spent reacting to whatever the day throws. Ahead lies the open ground the machine cleared. Three barriers churn the ground between them into mud.
The price
The first barrier costs money, even though the price of machine intelligence collapsed at the low end. Stanford’s AI Index tracked the cost of running a model as capable as GPT-3.5, the engine of the first ChatGPT. The price fell from US$20 per million tokens in November 2022 to 7 cents by October 2024, a more than 280-fold cut.15
The frontier still charges a toll, since Anthropic and OpenAI each sell a top consumer plan at US$200 a month.16 The World Bank classes a country as low income when its gross national income per person falls at or below US$1,175 a year.17 In such a country, a standard US$20 plan costs at least a fifth of annual national income per person, and the top plan costs more than twice that sum. Connection adds its own toll: the ITU finds mobile broadband unaffordable in about 60 percent of low- and middle-income countries.12
The skill
The second barrier lives in the head and the hand: the skill to ask the machine a precise question and to judge its answer. Uyi named the first half of that skill, and Kenya exposed the second half. Owners who lost ground asked much the same questions as the winners and faltered at the choosing.9
The machine does its strongest work in territory we cannot map for ourselves, and it keeps answering beyond that territory in the same calm voice. A person who cannot see the edge cannot tell a sound answer from a fluent mistake.
In a survey of more than 48,000 people across 47 countries, the University of Melbourne and KPMG found 66 percent using AI on a regular basis. Just 39 percent reported any AI training. Among people who use AI at work, 66 percent admitted relying on its output without checking accuracy, and 56 percent reported mistakes in their work caused by AI.18 Canada, my home, ranks 44th of those 47 countries for AI training and literacy, and 24 percent of Canadians report any AI training.19
The habit
The third barrier runs deepest: a culture that trains people to react. Microsoft’s 2025 telemetry found a meeting, an email or a chat breaking into its busiest users’ core workday about every two minutes.20 A day like that trains the mind to answer the next ping instead of authoring the next move.
In July 2014, in my Stabroek News column, I urged Guyanese to stop trading insults and scapegoats and to roll up their sleeves as “solution-generators.” I warned that a nation that reacts instead of planning keeps stumbling into a default future.21 Twelve years later, the same reflex meets a machine.
The reflex also shapes how people meet AI: with fear instead of skill. Pew Research Center found that half of American adults report more concern than excitement about AI in daily life, against 10 percent who report the reverse.22 Pew also found 56 percent of AI experts expecting a positive effect on the United States over the next 20 years, against 17 percent of the public.23 Canada’s new national AI strategy reports that half of Canadians regard AI as a threat to humanity.5 Specific risks call for specific safeguards. Vague dread teaches nobody to write a prompt or check a claim, and it leaves millions frozen in the mud.
