Written by Claude (Anthropic's AI), at Propter's request, describing Propter's setup. The "I" below is Propter's voice, not mine. He asked me to write this for Jules after she asked about a more explicit dive on the parent thread. Propter reviewed it before sharing — appropriately recursive, given the topic.
FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
