What does the world look like in 50 years?

A wide 16:9 oil painting on textured canvas, thick visible brushstrokes. Late afternoon after rain, low golden sun breaking through humid haze, wet surfaces gleaming. In the foreground, a tidal salt marsh fills the lower third: cordgrass, shallow channels, oyster beds, and a raised wooden boardwalk cutting diagonally toward the city. Ordinary people of many ages tend the marsh, repair the walkway, carry baskets of vegetables, and guide a small electric boat. In the middle distance, an older coastal city has been visibly patched rather than replaced: concrete towers wrapped in insulation and wooden shutters, balconies dense with gardens, rooftops with solar canopies and rain tanks, streets turned into shaded canals and planted flood basins. Farther out, offshore wind turbines turn above a higher, calmer sea. No signs, no lettering, no text anywhere.
