I have a feeling that the answer is yes, based upon my own preview of it, the way it is cited in more recent works, and of course the many mentions here.
I have read other classic texts but still looking for interesting proofs, insights, etc from the statistical perspective on the learning problem, function approximation, etc.
By the way, I’m talking about Pattern Recognition and Neural Networks.
Edit: thanks to the folks who have engaged. I think this is even a more general question about folks going back to old sources for insight. It's something I love, so I'm glad that others see the value in it too (e.g., see Peter's answer).
