The only time I've encountered ARM SVE being used in the wild is in the FEX x86 emulator (https://fex-emu.com/FEX-2407/).

I, too, hate progress. By the way, the AMD Athlon 3000G system I helped build for a friend has AVX2. Even the old HP T630 thin client (https://www.parkytowers.me.uk/thin/hp/t630/) I bought for $15 as a home network router has AVX2.

7-zip's development is very cathedral. Igor Pavlov doesn't look like he accepts contributions from the public.

It's 14nm. Also, it was speculated to have L4 cache.
