That EWD is one if my pet peeves. Dijkstra makes an unfair comparison because he lists plenty of examples where 0-based indexing is more convenient but ignores the equally numerous situations where 1-based is more convenient. For example, iterating backwards over an array is much better in an 1-based world.
I like the argument that 1-based is better for indexing and 0-based is better for offsets: https://hisham.hm/2021/01/18/again-on-0-based-vs-1-based-ind...
