Ethan Mollick is an Associate Professor at Wharton, University of Pennsylvania, head of their Generative AI Lab, and author of the new book CO-EXISTENCE, just released, and on the NY Times bestseller list right away. His prior book CO-INTELLIGENCE was also huge hit, NYT bestseller. He writes ONE USEFUL THING on Substack, which is one of the most insightful and popular series of essays on AI on the platform.
Let me highlight that Ethan evaluates all of the new models independently and is not funded by any of the AI companies, which puts him in a singular or rarified group of experts.
Here are some of the topics we discussed:
-
The Jagged Frontier (the term Ethan came up with that has been adopted by all)
-
The end of Prompting
-
The Next-Token Train
-
The Bitter Lesson
-
Deskilling and Never Skilling
-
Hyperscaling and Recursive Self-Improvement (RSI)
-
Data Centers
-
Claude Table 5.2 (his new essay with a mind blowing video not to miss)
-
Safety of AI and Existential Threats
-
Personal AI Agents (Muse and Dot)
-
Education
-
Science, Authorship, Peer Review
-
Medical AI—Doctors out of the loop, AI potentially better than doctors with AI
-
Ethan’s use of Agents (from his new essay)
