Why hasn't 128 bit been introduced yet? (alien.top)

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?

If it took 21 years to go from 32-bit to 64-bit, imagine it will take about 21^2 = 441 years to go from 64-bit to 128-bit. This is because 2^128 / 2^64 is the square of 2^64 / 2^32.

Technology moves at an exponential pace. The time it took to go from 8 bit to 16 bit to 32 bit to 64 bit got shorter and shorter.
