Reflections on AI's Bitter Lesson and the Decline of Decision Theory

By

2mo ago· 6 min readenInsight

Summary

The author reflects on their experience writing about decision theory being abandoned in mainstream AI, only to be told by Hacker News commenters they were 'annoyed at the Bitter Lesson.' This prompted them to read Rich Sutton's 2019 essay, which argues that general computational methods consistently outperform human-crafted knowledge systems. The author explores how this 'bitter lesson' relates to their original point about decision theory's decline, noting that the misreading actually proves their argument about how AI discourse has shifted away from formal reasoning toward data-driven approaches.

Rich Sutton's essay, published in 2019, argues that general methods leveraging computation consistently beat methods built on hand-crafted human knowledge.
The misreading proves the point.

I wrote about decision theory fading from AI. Hacker News said I was annoyed at Rich Sutton's Bitter Lesson. I wasn't. But the misreading proves the point.
