2049 is a year in the Gregorian calendar. It is the 49th year of the 21st century (2001–2100). In real-world contexts, 2049 is often used as a horizon year for long-term planning and scenario analysis. Common themes in such projections include continued urbanization, advances in automation and artificial intelligence, and energy transitions toward low-carbon systems. Climate-change adaptation and resilience, global governance, and shifting demographics are also central to mid-century planning, though expected outcomes vary by region and scenario. In culture, 2049 is best known as the setting of the film Blade Runner 2049 (2017), directed by Denis Villeneuve. The movie, a sequel to Blade Runner (1982), depicts a dystopian future in which synthetic beings and human society intersect with questions of memory, autonomy, and social inequality. The year has since been used in other speculative and science-fiction contexts as a marker of technological advancement.
