I've got two RK3588 boards here doing Linux-y things around my place (Jellyfin, Forgejo builders, Immich, etc) and ... I don't think I've run into pain? They're running various debian and just ... work? I can't think of a single package that I couldn't get for ARM64.

Likewise my VPS @ Hetzner is running Aarch64. No drama. Only pain is how brutal the Rust cross-compile is from my x86 machine.

I mean, here's Geerling running a bunch of Steam games flawlessly on a Aarch64 NVIDIA GB10 machine: https://www.youtube.com/watch?v=FjRKvKC4ntw

(Those things are expensive, but I just ordered one [the ASUS variant] for myself.)

Meanwhile Apple is pushing the ARM64 architecture hard, and Windows is apparently actually quite viable now?

Personally... it's totally irrational, but I have always had a grudge against x86 since it "won" in the early 90s and I had to switch from 68k. I want diversity in ISAs. RISC-V would be nice, but I'll settle for ARM for now.
