Your post is making me think maybe there is quite a lot of lost knowledge out there somewhere that maybe has pertinence in modern day agentic AI system building use.

I agree with that. In fact, that mindset is what led me to this book in the first place. I was exploring an older book on OPS5[1] and saw this book mentioned, and started looking for it and found that it is freely available online. Seemed like something the HN crowd might enjoy, so here we are.

And that is making me look more and more in to old techniques that have been long established way back when...

I suspect that there is some meat on that bone. I'm exploring this particular area as well. I think there's some opportunity for hybridization between LLM's / GenAI and some of these older approaches.

I spent several years working with OPS5 in the 1980s. The Common Lisp code, especially the Rete network stuff, was fairly straight forward to modify and generally work with. Good times.
