Wired has a fascinating story about two AI researchers, both of whom committed suicide.
In 1991, Singh went to MIT to study artificial intelligence with his idol and soon attracted notice for his passion and mental stamina. Word was that he had read every single one of the dauntingly complex books on the shelves in Minsky’s office. A casual conversation with the smiling young researcher in the hallway or at a favorite restaurant like Kebab-N-Kurry could turn into an intense hour-long debate. As one fellow student put it, Singh had a way of “taking your idea and showing you what it looks like from about 50 miles up.”
The field of AI research that Singh was joining had a history of bipolar behavior, swinging from wild overoptimism to despair. When 2001 came out in the late ’60s, many believed that a thinking machine like HAL would exist well before the end of the 20th century, and researchers were flush with government grants. Within a few years, it had become apparent that these predictions were absurdly unrealistic, and the funding soon dried up.
