2140s

The 2140s refers to the decade from 2140 to 2149 in the 22nd century. It is a period defined by ongoing technological change, demographic shifts, and the maturation of space-enabled economies. As with many long-range forecasts, analysts describe several plausible trends, though concrete outcomes will depend on policy choices, breakthroughs, and global cooperation.

Technology and economy: Automation and artificial intelligence are expected to be deeply embedded in daily life and critical infrastructure. Energy systems may rely on a mix of renewables, advanced storage, and new generation options. Advances in materials science and manufacturing could enable more efficient production, more resilient supply chains, and new urban and industrial designs. These changes are likely to affect employment, privacy, and the organization of cities.

Space and environment: The 2140s could feature expanded space infrastructure, including permanent lunar or orbital facilities and early commercial extraction of space resources. Climate adaptation continues to shape urban planning, building standards, and disaster resilience, while climate policy cooperation remains a major geopolitical issue.

Society and culture: Educational models using artificial intelligence tutors and personalized learning may become common. Demographic patterns—such as aging populations in some regions and youth dynamics in others—influence social policy and healthcare. The cultural landscape may reflect greater global connectivity and cross-cultural exchange.

Geopolitics and governance: Technological assets and space capabilities create new strategic considerations. International governance debates focus on data sovereignty, cybersecurity, and regulatory frameworks for AI and biotechnology. Economic power may increasingly depend on technology and space industries.
