Melanie Mitchell: Concepts, Analogies, Common Sense & Future of AI
Lex Fridman Podcast
Deep Dive
Why does Melanie Mitchell not like the term 'artificial intelligence'?
The term 'artificial intelligence' is vague and means different things to different people. It also doesn't clearly define what intelligence is, as there are many types and degrees of it. John McCarthy, who coined the term, later regretted using it.
What is the main distinction between weak AI and strong AI according to John Searle?
Weak AI involves machines simulating thinking or carrying out intelligent processes, while strong AI posits that a machine is actually thinking, not just simulating it.
Why have humans historically been fascinated with creating artificial intelligence?
Humans have been driven by a desire to better understand their own thought processes and to create machines that can mimic human cognition. This fascination is deeply rooted in the mythology and ethos of the species.
Why are humans bad at predicting the future of AI development?
Humans struggle to predict AI's future because they have limited understanding of their own intelligence. Tasks that seem simple to humans, like vision, are actually incredibly complex and involve unconscious processes that are invisible to us.
What does Melanie Mitchell believe is the most important open problem in AI?
The most important open problem in AI is how to form and fluidly use concepts. This involves understanding how humans create and apply concepts, which is central to cognition.
What role does analogy making play in human cognition according to Melanie Mitchell?
Analogy making is fundamental to cognition. It underlies how humans form and apply concepts, recognize situations, and generalize knowledge. Without analogies, there can be no concepts, and thus no thought.
Why does Melanie Mitchell believe that autonomous vehicles face significant challenges?
Autonomous vehicles struggle with the open-ended nature of the real world, including edge cases and the long tail problem. They lack common sense and the ability to interpret obstacles correctly, leading to overly cautious behavior.
What does Melanie Mitchell think about the fear of superintelligent AI?
Mitchell believes that the fear of superintelligent AI is overblown. She argues that intelligence is not easily separable into dimensions like rationality and values, and that a superintelligent AI would inherently understand human values.
What is the Santa Fe Institute and what is its focus?
The Santa Fe Institute is a research organization founded in 1984 that focuses on interdisciplinary studies of complex systems. It brings together scientists from various fields to study emergent phenomena and general principles underlying complex systems.
What lesson from Douglas Hofstadter has influenced Melanie Mitchell the most?
Hofstadter taught Mitchell to idealize complex problems to their essence, focusing on the core aspects that need to be solved. This approach has been a guiding principle in her research, particularly in creating the Copycat program.
