Letters between Backus and Dijkstra (1979)
This is a series of cell phone shots of an exchange of letters between Backus and Dijkstra. There is no transcript and some of the letters are hard to read, especially the handwritten ones.<p>I only skimmed it but it is definitely an interesting read.
I didn&#x27;t interpret their stance as arrogant though. In my book both are enthusiastic about their subject and think the other party is misguided. Both take some effort not to hurt the others feelings while still bringing their point across.
