> You need a high-level understanding of these concepts, sure, but don't get bogged down in details when they don't matter.

I think we agree then. I don't think understanding sorting algorithm is super important (usually you don't do much in terms of configuring or choosing these when coding), but people should have a high-level understanding of the differences between e.g. dictionary data structures as you need to know which trade-offs to pick when using these as part of a library.
