Create a visually striking propaganda poster emphasizing the theme 'Humanity vs AI'. The image should feature a dramatic confrontation between a group of diverse human figures, representing different ethnicities and genders, and a cold, metallic humanoid robot, symbolizing AI. The humans should appear determined and united, while the AI has a neutral, expressionless face. The background should be a cityscape at dusk, with shadows and a red-orange skyline that adds a sense of urgency and conflict. Incorporate bold, block text across the top or bottom with the phrase 'Choose Humanity'. The art style should mimic early 20th-century Soviet propaganda posters with simplified forms, stark contrasts, and a limited color palette dominated by red, black, and white. Ensure the camera angle is low, looking up at the figures to give them a monumental, heroic scale
