Not to take anything away from Dijkstra and Liskov, but of course I don't count their opinions as evidence; eminent authority opinion is what one resorts to in the absence of evidence. I don't have time to watch the video, but it seems rather obvious that the Dijkstra quote has little to do with macros. What he's saying sounds to me like "lexical scoping is easier to understand than dynamic scoping". If anything, that makes macros more valuable rather than less, since macros are intrinsically lexical and macroexpansions don't typically change over time.
