"The big obstacle, though it's not an obstacle because I think it will just take time, is the computer has to learn more about the way we see the world."

"It's very hard to understand the world from a human perspective. Intelligence relies on the way we view the world as humans, and the way we think about the world."

"Computers are just starting to be able to hear and starting to being able to see images. Those are tremendous improvements in the field in the last five years."

"We're doing that by having computers read millions of texts and pages from the web, by hooking them up to cameras and moving them around human environments."
