> This will take decades because you cannot change existing architectures/processors.
I think once, AVX-512, SVE and RVV are wide spread enough, you'll have a rather powerfull baselevel you can target. But this will take a lot of time.

Which subset though? Some of them are not supported by some recent CPUs (e.g. 2024).
Not to mention Alder Lake not supporting AVX512.
For at least the next decade AVX 512 will be the high performance target, reaching all of the zen4/5/6 CPUs as well as whatever avx-10 enabled CPUs Intel producers.
