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?
You are implying that all versions of x86 were 32 bit. 1978 was when the 8086 was released, Intels first 16 bit CPU. Intel’s first 32 bit CPU was the 386, released in 1985.
