I'm curious about the docker image situation. I had thought that the M1 could natively emulate x86 instructions. So why then can you not run the native x86 doc

  It does, which is slow, then the disk emulation makes it slower. Yes you can do it, but it’s not much fun. Improvements are on the way.

  Apparently, it does work in most cases, but aarch64 images have better performance and are more stable. https://docs.docker.com/desktop/mac/apple-silicon/ https://docs.docker.com/desktop/mac/apple-silicon/

  The M1 does not emulate x86 instructions (in hardware). Emulation is provided by Rosetta 2, a combined ahead-of-time and just-in-time emulation that can run x86-64 macOS binaries on Aarch64. However, there is still some hardware support for Rosetta 2 in the M1, e.g. to support strong memory ordering.

  There is no hw emulation, it's all software.
