The estimated number of atoms on earth is on the order of 1e50, which is 60 bits. If you take the 4 bits out of the 64bit address for tagging, you can still address individual atoms.
EDIT: My math is bad, see comments below.
I can unsarcastically say that no one will ever need full 64bit addresses on this planet.

- sherincall 6y agoYes, you're totally right, my math is way off.
- jmgao 6y ago10^50 is definitely not 60 bits: log_2(10^50) = 50 * log_2(10), and log_2(10) > 3
