Exclamation Re: What are the limits of 64 bits?
Commodity 64-bit hardware isn't properly 64-bit. Addressing is limited to 48 bits. The other 16 bits are not used at present, but can be in future hardware, so it's not a real problem.

I doubt we'll switch to 128-bit. Some other (perhaps quantum, or possibly even analogue) architecture will supersede 64-bit.
