I'm not intentionally trying to snub philosophy. With concrete theory, the point I was reaching for is that when you look to measure impact you probably want to point back to a compact articulation of an idea.
The book comparison was probably a cheap shot (on the other side of it, Einstein didn't need popular interest/approval for his ideas to matter; I think that is a positive).
I think as much as anything the comparison is worthless because we can look backwards at Einstein.
