x86 came out 1978,
21 years after, x64 came out 1999
we are three years overdue for a shift, and I don’t mean to arm. Is there just no point to it? 128 bit computing is a thing and has been in the talks since 1976 according to Wikipedia. Why hasn’t it been widely adopted by now?
32 bit has only 4 gigabytes which is easily saturated by a single socket computer while 64 bit has 16 million terabytes of addressable possible memory,. you will never see that number ever used in a single socket machine in the history of humanity.
