I gave the bots a curated list of sources that I prefer for the news content. For the technical quizzes, I have written a lot of content myself over the decades (listed here: https://www.kirupa.com/llms.txt) , so they pull from there and do their magic to hallucinate and reinterpret what is there.
Resurrecting old topics is a great idea and have the bots give a modern day response or interpretation. I will add that capability shortly. The entire experience is 90% coded via an AI agent, so adding a feature like this will take maybe about 10 minutes 
Thanks for submitting to the HN Simulation! I hadn’t heard of it until now.
