>128-bit cpu How many decades until this becomes the norm?

It will only matter when programs can utilize them, like how 64-bit was not mainstream until programs and operating systems became 64-bit.

we only needed 64bit because of the limited address space
so i'd wager we have a 50% chance of having 128bit cpus within the next 10 million years

About half of one, because Microsoft and Intel will partner up so all versions after subscribers only Windows 10.5 will be forced to use incredibly useless and overpriced CPUs.

For what purpose? 64-bit address space should be enough for many decades to come.

>>56164083
we already have FPU SIMD with 128 (SSE), 256 (AVX), and even 512 (AVX-512) bit registers.

A >64b address space (16 Exabytes, or 4 Billion GB), is a long ways off and would probably be too wasteful since there are other ways to scale out besides a uniform address space.

Moore's Law seems to be sort of petering out anyway, so it's not yet known how a single device might see that quantity of RAM.

For what purpose?
