"My goal is making machines that can think—by understanding how people think. One reason why we find this hard to do is because our old ideas about psychology are mostly wrong. Most words we use to describe our minds (like "consciousness," "learning," or "memory") are suitcase-like jumbles of different ideas. Those old ideas were formed long ago, before "computer science" appeared. It was not until the 1950s that we began to develop better ways to help think about complex processes."
