What is AI?
• Turing’s definition
• Are we there yet?
• Eliza (the original)
• Alice
• Joan
My Definition
Artificial intelligence is the study of how to make computers do things that people are better at or would be better at if:
• they could extend what they do to a World Wide Web-sized amount of data and
• not make mistakes.
The Key Components
• Perception
• Knowledge
• Reasoning
• Language
• Moving around
We’re Still Ahead on Perception

But What About Knowledge?
• Why do we need it?
• How can we represent it and use it?
• How can we acquire it?

The Three Laws of Robotics
• A robot may not injure a human being or, through inaction, allow a human being to come to harm.
• A robot must obey orders given to it by human beings except where such orders would conflict with the First Law.
• A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
