I think healthy optimism is good. I am with you that tech advancement is awesome. That wrist watch is very impressive. Yet its benefits over a 1900 pocket watch are not exactly on par with the benefits of a 1970s airplane over the benefits of a 1870s horse. (Intentional Hyperbole) I am not saying the author of the book is right, but I do buy a partial stagnation argument. I’d call it “hard physics”, or “large scale physics”. Maybe it’s interminent. Fusion could be around the corner. Maybe physics isn’t this never-ending tree of useful knowledge - maybe the science method allowed us to quickly exhaust the low hanging fruit.
