Creating a real ghost in the shell

Yasuo Kuniyoshi is a man with an extraordinary plan. Kuniyoshi, a professor at the University of Tokyo's Graduate School of Information Science and Technology, has been attempting to produce an utterly convincing artificial being for the past 30 years. "A robot," he says, "that has developed the real ability to understand correctly what people are saying, and is able to converse and interact with them naturally, just as humans do with each other, based on its own experiences and bodily sensations." I've been thinking about Kuniyoshi's work since seeing the recent Hollywood remake of "Ghost in the Shell." The original anime from 1995 was hugely influential and, together with "Akira" and "Spirited Away," is one of the most well-known Japanese animes in the West.
