Given how the 6502, 8051, and Z80 cores seem to show up in a ton of ultra-low-cost products (running at many times their original clock speeds, and using bank switching to extend the address space into the megabytes range), some even networked with ability to do TLS, the fact that a 6502 can do BLAKE3 isn't so surprising, and IMHO really helps reinforce the notion that crypto == math.
