What's the difference between your brain and a computer? It depends on who you ask of course, because it's a question that gets at the "big questions" of human consciousness. Are we mechanistic entities, systems that can be learned, programmed, and reproduced one day in the form of artificial intelligence? Is language a set of rules that can be unlocked and automatically translated?
David Bellos, a renowned translator, says no. Some problems of AI are and always will be unsolvable, because they're not merely technical in nature. Language and the brain functions in nuanced and complex ways that will never be replicated.
Others, like Stephen Hawking, see the brain as a switchboard. Dr. Michio Kaku argues that the line between the two has to do with the amazing flexibility of the human brain. Yes, it's a learning machine, but it's one that is constantly changing and adapting. Until computers can mirror that function -- which is a long way off -- there will be major differences in the way brains and computers operate.
