qemu can do userspace emulation, so you can run an aarch64 binary transparently on x86_64, as long as you have all the right libraries installed. You can also drop a Raspberry Pi image onto your computer, copy qemu-user-static into the image, chroot into it, and you've got a Raspberry Pi commandline without any physical Raspberry Pi. It's honestly pretty amazing.
