Artificial Intelligence and Creative Writing: A Policy of Sorts. I've posted versions before, but I update this each term following conversations with students. Here's my Fall '26 edition. In no way definitive! Learning as I go.
ABBREVIATED FOR ALT TEXT
This is a course for those interested in writing not as means to an end but as an end in itself. Recently... I read a story in New York magazine titled, “Everyone is Cheating Their Way Through College,” by James D. Walsh....
I didn’t think AI would be a temptation for creative writing students. “Everyone is Cheating Their Way Through College” persuaded me that for many students of all sorts it’s not a temptation but a condition. You sleep in a bed, you wear clothes, you don’t scream at teachers. Just the way it is. Maybe AI is becoming that, too, part of “just the way it is.” Maybe it is that already. 
	My mind raced through ideas about how to “beat” AI. The article dismantled them. Then I thought, “That’s not my job.” I’m a writer and a teacher. I’m not a cop. If you want to work with me on writing, we can do that. If you want to cheat, you have the ability to do that, too, and the truth is, I probably can’t stop you.... Per Dartmouth’s policy: “Students may not use GenAI tools for submitted coursework unless expressly permitted.” I do not permit it....
I’m interested in working with students for whom writing feels, somehow, good. Even if sometimes it’s painful. Who seek that feeling anyway. A feeling of being, of alertness. Of purpose; of intention. Of practice.
This is a course for those who are interested in using writing to experience some variation of this feeling. Sometimes it comes in a moment of clarity, sometimes in the making of a lyrical juxtaposition. There are so many more emotional, intellectual, and spiritual possibilities that arise from the act of shaping language... There is no paycheck, or even a finished book held in hand for the first time, that has ever brought me as much complicated pleasure as the arrangement of words. Maybe you’re like this, too. Or maybe you want to be. If so, I designed this course with someone like you in mind.

This sadly doesn't surprise me. I'm aware of harassment and discrimination in academic settings I have been in and how they're very rarely reported because nobody believes anything tangible or close to justice will ever come of it. I despair of academic ivory towers & their silence on these things

For me, it’s #cassiterite today! The primary tin ore mined since the Bronze Age. It’s found in placer deposits and in veins in some granites. You can find cassiterite in Cornwall, Bolivia, Australia, Indonesia, and other places around the world. #MinCup26

We had writing without need for #Graphite in a pencil, at the same time #Cassiterite was critical at forming the first metal-based civilisations. This seems a no-brainer to me.

Nepal *landslide* (and a chunk of glacier) Landsat-9 images “revealed a huge rock landslide had indeed occurred. “The glacier just came along for the ride,” Ekström says.” “Byers points a finger at the gradual thawing of high-altitude permafrost, which binds rock and ice together.”

The sheer scale of destruction amid Himalayan glacier collapse disaster is horrifying, as is presumptive human toll. This was no mere flash flood or mudslide--it was more akin to a geologic-scale debris avalanche or "inland tsunami." The footage emerging is almost unbelievable.

Dreadful scenes from the devastating Rasuwa flood in Nepal/Tibet. My heart goes out to everyone affected. It likely began with a glacier collapse / rock–ice avalanche recorded by seismometers worldwide. I hope real-time seismic monitoring can support early warning for communities downstream.

Some early reports said that the horrifying flooding in Nepal was the result of an earthquake. However, the signal was actually the recording of the landslide. TL:DR - there was no earthquake, it was a landslide. earthquake.usgs.gov/earthquakes/...

77 years ago tonight - a M8.1 #earthquake off #HaidaGwaii ruptured a 500-km-long segment of the Queen Charlotte Fault ("Canada's San Andreas Fault"). The average slip along the #fault was ~5 m. Shaking was so strong that it was hard to stand. More than 100 aftershocks were felt on Haida Gwaii. ⚒️🧪🇨🇦

Outside of local triggering (eg., aftershocks), the global distribution of big earthquakes is random in time. That means there is an average rate (15 M7+ evets/yr) but the time since the last event doesn't matter. Sometimes we see clusters - if there were no clusters, it woldn't be random.
