I think you're right. You're not the only person in the thread with this feedback. I read this book and thought I could contribute, but I haven't read anything with more recent context. (Haven't even finished the book yet, still working on it.) So yeah, I appreciate this callout, I apologize, and I'll try to do better next time.
Ah, you would have been right about 10-15 years ago. Things have dramatically changed since then. I'm assuming you've not had any contact with the medical system requiring opiates for you or your relatives in recent years. Now, we've swung far, far too far to the other extreme, to the point that my WWII vet, community leader, church deacon grandfather was brutally undertreated for pain while he was dying of cancer. This is very typical now.
Either that, or the medical system is very different in Silicon Valley or wherever you live.
