In 20 years, around 2045, Earth is expected to undergo significant changes driven by technological advancements and environmental challenges. A major milestone anticipated is the technological singularity, where artificial intelligence (AI) reaches a level that fundamentally reshapes human society and culture. By then, AI could perform all kinds of intellectual and mundane tasks, potentially leading to widespread automation and societal shifts.

On the environmental front, climate change impacts are predicted to worsen, with increased extreme weather events, rising temperatures, and water shortages. Efforts to undo environmental destruction through advanced technologies will likely be crucial. Additionally, shifts in population dynamics and resource scarcity could lead to social and economic stresses.

Other anticipated developments include highly advanced computation with supercomputers reaching zettaflops capacity, widespread use of electric and autonomous vehicles, commercial fusion power, graphene applications, space exploration including space elevators and moon bases, and medical advances notably reducing diseases like cancer and AIDS.

Overall, the world in 2045 will be technologically transformed, facing critical environmental challenges and social changes, with AI playing a central role in daily life and problem-solving.
