Summary
This document discusses the history of artificial intelligence (AI), including the hype around different AI approaches. It touches on the potential for AI to cause social harm due to bias, misalignment with human goals, and potential for errors. The document examines the comparison of AI cognition with human cognition through various tasks like the false-belief and no-belief tasks.

(Last) Quiz and Attendance! Reminders Paper #3 due December 9th During class time on December 9th: Come here (304 Barnard Hall) if you want to take the final Join Zoom (through Canvas) if you’d like to attend a review session, and take the final on December 18th as officially scheduled Artificial Intelligence Hype level ”We propose that a 2 month, 10 man study of artificial intelligence be carried out during the summer of 1956… An attempt will be made to find how to make machines use language, form abstractions and concepts, solve kinds of problems reserved for humans, and improve themselves. We think that a significant advance can be made in one or more of these problems…” 1956 1960s 1970s 1980s 1990s 2000s 2010s 2020s Hype level Newell & Simon’s Physical Symbol System hypothesis: any system exhibiting intelligence must operate through symbol manipulation 1956 1960s 1970s 1980s 1990s 2000s 2010s 2020s Hype level 1956 1960s 1970s 1980s 1990s 2000s 2010s 2020s Hype level 1956 1960s 1970s 1980s 1990s 2000s 2010s 2020s Hype level 1956 1960s 1970s 1980s 1990s 2000s 2010s 2020s Hype level ImageNet Fei-Fei Li 1956 1960s 1970s 1980s 1990s 2000s 2010s 2020s Return of Neural Networks Hype level 1956 1960s 1970s 1980s 1990s 2000s 2010s 2020s ?

Racist chatbots 2. Racist Youtube recommendations 3. Racist prison sentences Bias Viscous feedback loops 1. Identify an area for extra policing 2. More criminal activity found in that area 3. Identify it as in need of still more policing 4. Etc. Misalignment Goal satisfaction A parable “But, say one day we create a super intelligence and we ask it to make as many paper clips as possible. Maybe we built it to run our paper-clip factory. If we were to think through what it would actually mean to configure the universe in a way that maximizes the number of paper clips that exist, you realize that such an AI would have incentives, instrumental reasons, to harm humans. Maybe it would want to get rid of humans, so we don't switch it off, because then there would be fewer paper clips. Human bodies consist of a lot of atoms and they can be used to build more paper clips. If you plug into a super- intelligent machine with almost any goal you can imagine, most would be inconsistent with the survival and flourishing of the human civilization.” - Nick Bostrom Social harms Ways that AI can become dangerous 1.
