Annoyingly maybe the most important book doesn't have an image on amazon.

I do not think I am mistaken. In particular, citing 2014 data is not very useful given the shifts recently. See here for eg FIRE's recent survey, which discusses this issue explicitly.

Here's a scatter plot of final exam grade vs a heuristic "AI score" for students in my intro class (for maximum irony the scoring program and data analysis were written by AI). There was less correlation than I expected and lots of people with a score of 0.

It's more than just generalizing from yourself, it's that constructivism being true is a very nice thing to think about teaching and learning and students. Think about the slogan in this image, which is on many teachers' walls:

Over the 10 days, I wrote a new Racket library for "expect testing", a style that @yminsky.bsky.social has advocated for in OCaml. github.com/samth/recspe... As an experiment, I built it entirely with Codex (the OpenAI async AI programming tool). I have some thoughts.

It makes me very angry that the new @citybloomington.bsky.social greenway, which we spent a million dollars on, is entirely blocked here because not only has it not been plowed, but the city plowed snow _onto_ the path at the end.
