Political violence is bad. It usually begets more political violence. Celebrating political violence is bad. It usually encourages more political violence, against various targets. Campus shootings are bad. They make everyone on campus less safe. It's bad that what I wrote here is controversial.

I've been talking about interference weights as a challenge for mechanistic interpretability for a while. A short note discussing them - transformer-circuits.pub/2025/interfe...

A number of people have asked me why we titled our recent paper "On the Biology of a Large Language Model". Why call it "biology"?
The elegance of ML is the elegance of biology, not the elegance of math or physics. Simple gradient descent creates mind-boggling structure and behavior, just as evolution creates the awe inspiring complexity of nature. x.com/banburismus_...
