- api 4y agoThe addressable size grows exponentially with more bits, not linearly. 2^64 is not twice as big as 2^32. It’s more than four billion times as big. 2^32 was only 65536 times as big as 2^16. Going past 2^64 bytes of local high speed RAM becomes a physics problem. I won’t say never but it would not just be an evolutionary change from what we have and a processor that could perform useful computations on that much data would be equally nuts. Just moving that much data on a bus of today would take too long to be useful, let alone computing on it.
