Special relativity sounds like a theory for astronauts and particle physicists, but it's already running in your phone, your wedding ring, and the cosmic-ray shrapnel currently passing through your skull. Loki explains how, and why nobody told you.

An explainer on how large language models actually work—tokens, embeddings, attention, parameters, training, and why the whole apparatus produces something that sounds so much like thinking.

In which Loki contemplates Voyager's 69-kilobyte computer, the 73,000-year journey to the nearest star, and the cheerful humiliation of sending your absolute best into a universe that will still have time to get dramatically better at everything.
