My problem is that I want to store more than 4 million items in an array. You're suggesting moving to 64 bits? And even if everyone magically moves to 64 bits, I can imagine that in the future someone will want to read more than 2^(64 - 10) items from a file into memory, as 64 bits isn't quite "number of atoms in the universe" big yet.
