There is a lot of fuss today over whether chatbots can replace human participants in social sciences research when the solution is obvious: ask chatbots to simulate the views of social scientists and survey them on attitudes towards chatbots as substitutes for human subjects.

A little thread on how the crisis around GenAI in academia is also a crisis of confidence, and it makes me quite sad. [1/n]

Here's a recording of my talk on the role of computers in making art, including so-called "AI", which was presented as the opening keynote of SIGGRAPH 2025, incorporating lessons from the history of computer graphics, photography, modern art, and philosophy of art. www.youtube.com/watch?v=c2YR... 1/

There's a nice article by Siobhan Roberts about the Bridges 2025 conference in Eindhoven in the NY Times. I can now say that I am in The NY Times! (A photo credit for the shot of Chaim Goodman-Strauss and Edmund Harriss,... but still!) www.nytimes.com/2025/10/10/s...

I heard AI and its relationship to the economy recently described as “The wasting is masked because the tumor is growing so fast that the body isn’t losing weight.”

Grant Sanderson was scheduled to speak at Bridges 2025, but couldn't make it. Instead, he filmed a special behind-the-scenes and sneak preview of this video, which was partly finished, for the conference. I look forward to watching the final product! (Topic: Sol Lewitt + Burnside's lemma)
New video about a piece by the modern artist Sol LeWitt, and the group theory behind it.

Hegseth is now the Secretary of War, which is fitting I guess as RFK jr is basically the Secretary of Pestilence. We just need Famine and Death to round it out.

The “problem” with vaccines? They so effective at preventing deaths that they create generations of people that question whether disease was a problem in the first place because they have never experienced the horrors of a world without vaccines.

RIP Graham Greene. To me he will always be Leonard, the shaman who came to town from time to time in Northern Exposure. I just rewatched my favourite episode in which he appears: “Three Doctors” (s5e01). bsky.app/profile/jord...
RIP Graham Greene. Every time he popped up on screen when I was a kid, my mom would excitedly point him out for being an actual Native on the screen. Able to be deadly serious and infinitely hilarious (even in smaller roles like Last of Us), he ate up the screen. Nʌki’wah brother.

I would read an academic murder book in which the murder was solved by reading the syllabus
I love this idea and also want a list of academic murder books. Please reply with recs
Hear me out: a dark academia murder book that opens at a department beginning-of-the-year celebration on a boat (I know a department that does this) and a professor goes overboard. The intrepid department chair must figure out who did it. Everyone is a suspect, including the chair herself.
