> Haskell beginners often use lists instead of arrays. You can’t do random access in a linked list, but only access the first element and then the rest of the list. The real world also doesn’t allow you random access, you are limited by the speed of light and have to go from one location to the next.

You don't need arrays for random access though. Haskell trees give you access to 2^n leaves within depth n, which also exceeds physical limitations like the speed of light.
