Prompt
Create a realistic portrait of K. Eric Drexler, a middle-aged man with a gentle smile, wearing a pair of glasses and a suit, sitting in a library or a study with books and papers around him, with a subtle background that hints at his connection to nanotechnology and futurism. The style should be a photorealistic representation, with attention to detail and texture, capturing the essence of a renowned engineer, author, and futurist.
