Create a vibrant and bold image of Elon Musk immersed in contemplation, depicted in a Neo-Pop Art style. Capture his focused facial expression as he ponders groundbreaking ideas, surrounded by symbols of his diverse ventures, including Tesla, SpaceX, Neuralink, and The Boring Company. Use a bright and saturated color palette featuring vivid shades of red, blue, yellow, and green, accompanied by striking black outlines characteristic of Neo-Pop Art. Introduce collage elements by blending photographs, text, and graphic designs to craft a visually arresting composition that mirrors the dynamic energy of Musk's entrepreneurial spirit. Position him at the center of the scene, with various symbols and elements emanating from his reflective expression, and make creative modifications while maintaining the essence of the concept.
