A recent BBC report states that, potentially, the Death of Alan Turing might not have been a suicide [article here]. While reports of how “happy” or “good-humored” Turing seemed to others, after his chemical castration due to homosexuality, are not to be trusted (he could have been putting on a brave face out of fears of worse punishment), the description of the circumstances of his alleged suicide are a little inconsistent. The half-eaten apple was part of his daily routine, and he was working with cyanide in one of his experiments. Perhaps it wasn’t so much a conscious suicide as an accident resulting from a general depression he was careful to conceal. After all, he was by no means under ordinary pressures or circumstances -- great scientist though he was.
Aside from his many accomplishments, Turing is famous for the “Turing Test”, which measures the ability of a hypothetical machine to imitate a human (some say to “fool” a human) in the context of a “parlor game” where an interviewer asks questions and hears back responses that are meant to be “male” from first a woman and a man, then a computer designed to sound like a woman pretending to be a man and a man. No computer has yet been made that would satisfy the requirements of this “test”.
