By 2100, humanity is likely to face a paradoxical situation: demographic decline and aging in some regions will be combined with growth and youth in others, while technology, especially artificial intelligence, will become the main driver of the economy. The key choice is between the scenarios of \"too little, too late\" and \"a giant leap\". Demographics: peak passed, the world is aging According to UN forecasts, the world's population will reach a peak of approximately 10.3 billion around 2084, after which it will slowly decline, reaching about 10.2 billion by 2100. The main reason is the decline in fertility: in more than half of the world's countries, the total fertility rate is below the replacement level (2.1 children per woman). This will lead to a radical change in the population structure. Aging. The number of people over 65 will more than double — from 857 million today to 2.4 billion by 2100. Their share will grow from 10% to 24%. For the first time in history, older adults and young people under 25 will be represented by approximately equal proportions. Leadership change. China, whose population is expected to decline from 1.4 billion to 633 million, will be replaced by India. African countries (Nigeria, DRC, Ethiopia, Tanzania) will become the main drivers of global growth. Migration. To mitigate the effects of aging, developed countries will be forced to either stimulate fertility or actively attract immigrants. Studies show that with a complete halt to immigration, the US share in global GDP could fall from 14.4% to 9.2% by 2100. Technology: artificial intelligence as the foundation of the economy and war By 2100, technology will become an integral part of the economy and security. Projections suggest that artificial intelligence and automation will determine global power. Field Forecast Economy Artificial intell ... Read more
