In my first interaction with ChatGPT 5 it provided four "key references," every one of which was hallucinated or broken in one or more ways. This was about a machine learning techique for which there is a lot of information online, and it totally butchered it.

Congratulations to Rich Sutton and Andrew Barto on receiving the Turing Award in recognition of their significant contributions to ML. I also stand with them: Releasing models to the public without the right technical and societal safeguards is irresponsible.

Via a friend, from MIT’s alumni magazine. On the confluence of Lisp-based Object Oriented Programming systems and gourmet ice cream in Cambridge, MA in the 1970s. I joined Symbolics in 1982 working with Dan Weinreb and Howard Cannon, writing a lot of Lisp code with Flavors.
