I moved to MIT from Stanford in 1984 to teach, and became the founding director of MIT's Computer Science and Artificial Intelligence Lab.

The most important thing for building a robot that you can interact with socially is its visual attention system. Because what it pays attention to is what it's seeing and interacting with, and what you're understanding what it's doing.

Two big questions that people ask me are: if we make these robots more and more human-like, will we accept them - will they need rights eventually? And the other question people ask me is, will they want to take over?

It's reasonable to say that certain things we understand should perhaps have limits on how they're used and how certain technologies are deployed. That's very much what we should do as a society.
