You might be confusing mean goal and end goal. Nobody needs to write a linked list, except when interviewing.

What you need (a feature, a performance improvement, etc.) is usually better served with other structures, especially in languages which don't heavily favor heap allocations (in a GC based language you've already paid the allocation cost when creating the object anyway).

I think there's now some evidence that Rust prevents developers neither from making efficient applications nor from efficiently making them.
