If every byte was set to the true 64-bit integer (1 decellion), this game would need ~200 TB of memory. So that is why these practical values exist.
No, 64 bits can index 2⁶⁴ or about 16 * 10¹⁸ tiles. In words this is sixteen trillion or sixteen pentillion, depending on whether you subscribe to the long or the short scale. This is nowhere near a decillion (10⁶⁰ or 10³³, depending on the scale). However, this is completely irrelevant. The relevant number is 8 bytes per tile (or 8 kilobytes per chunk) for the tile IDs, plus some memory for those tiles which have been assigned a meaning. There is no need to allocate memory for unused tile IDs.

As part of the Space Age work we had to bite the bullet and change tiles to support up to 65'000~ tiles. It means more memory used and potentially save file size but it's now going to be there.
HECK YEAH!!!! \o/

Out of all the changes to the game for 2.0/expansion, this one right here is getting me the most excited!!
