I’d be happy to port the article to ARM64 if there was sufficient demand for that, but I think it’s still fairly niche among developers, right? (Apple, recent Android, niche server environments?)
A subset of 32-bit ARM is quite common these days in education, often replacing where MIPS was once used.
ARM64 has really swept in the last couple years. My two year old budget Android smartphone has an ARM64. So does my Raspberry Pi. Lots of hardware hacker types likely to play around with assembly would be using ARM, and often 64 bit these days.
That said, it is relatively niche. A lot of those ARM64 machines are running 32 bit software still. But I do expect it to be the dominant architecture in just a couple years.
