No Effect Before Its Cause: From Einstein to Lamport

I remember years ago, I went to a Papers We Love talk about Lamport's vector clock papers. The speaker tried to tie Lamport's work to relativity. I happened to notice Lamport in the audience during the talk, curled up with his face buried in his hands, not exactly thrilled with what was being said.

I managed to ask him what he thought of the talk afterwards. If I recall correctly, he managed a very diplomatic response, something along the lines of "that was a unique perspective".
