Prompt
"Generate a realistic portrait of Silvio Micali, a middle-aged Italian man with a gentle smile, wearing a pair of glasses and a suit, sitting in front of a background that subtly suggests his connection to computer science and cryptography, such as a faint image of a computer screen or a cryptographic equation; he should be depicted in a thoughtful and introspective pose, conveying his status as a renowned computer scientist and professor at MIT, with a hint of warmth and approachability."
