Dr Hinton also accepted that his age had played into his decision to leave the tech giant, telling the BBC: "I'm 75, so it's time to retire." Dr Hinton's pioneering research on deep learning and neural networks has paved the way for current AI systems like ChatGPT. But the British-Canadian cognitive psychologist and computer scientist told the BBC the chatbot could soon overtake the level of information that a human brain holds.
"Right now, what we're seeing is things like GPT-4 eclipses a person in the amount of general knowledge it has and it eclipses them by a long way. In terms of reasoning, it's not as good, but it does already do simple reasoning. And given the rate of progress, we expect things to get better quite fast. So we need to worry about that."
