My two favorite talks so far from Emacsconf

Emacs Reader, talk, code, emacsconf page This talk described a fast new document reader that leverages dynamic modules. This made it work faster than docview or pdftools.

LLM & Emacs talk, talk, emacsconf page This talk explores what is "editing" and how different classes of emacs LLM tools goes with, or against editing. A quick tour of many tools + an easy going philosophical discussion.
