I can see 128-bit pointers being a thing: not because of 128-bits of address space, but for the ability to embed type information directly in the pointer - which could improve performance for dynamic-dispatch scenarios or runtime type-safety built-in to the hardware itself. > Having a native uint128_t would make dealing with IPv6 addresses a lot nicer though :) [We're already there](https://stackoverflow.com/questions/34234407/is-there-hardware-support-for-128bit-integers-in-modern-processors https://stackoverflow.com/questions/34234407/is-there-hardwa...)
