That aussie was just trying to jump into his dead friend's shoes. Nothing to see here - move along now.
Are you saying that Kleiman wrote the white paper too? Any such claim can only be bolstered by convincing rough-drafts.
The mathematician Paul Erdos spent years wandering the world alone, nearly penniless and living out of his suitcase going from one mathematical conference to another, each full of a range of strangers and overly familiar colleagues and buffet-quality food and drink. He turned down numerous well-paying professorships offering light teaching responsibilities and leaves of absence that would have allowed him nearly as much leeway to wander. He always turned the offers down. A lonely old man, but also the great and well-known Paul Erdos. Someone once asked the aging and soon-to-die Henry Luce, founder of Time magazine, why he continued to go to ghastly do-gooder conferences in hotel meeting-rooms full of buffet-quality food and drink and a range of strangers and overly familiar colleagues. "Because it is expected of me," he replied. A lonely old man, but also the great and well-known Henry Luce.
What satisfaction could the inventor of Bitcoin derive from going incognito to academic meetings to talk shop with a range of strangers and overly familiar colleagues over buffet-quality food and drink? Maybe he doesn't go at all, and prefers to just bide his time and get rich. Or perhaps he is dead.
From Edgar Allen Poe:
It will be in vain to follow, for I shall learn no more of him, nor of his deeds . . . "er lasst sich nicht lesen."
