@emmy I'd never have thought Intel emulation on ARM would work particularly well, given how very different the architectures are, but, Rosetta2 demonstrates it can be done with surprising efficiency, though inevitably with some cost.
Could be interesing to see how well optimised QEMU's emulation is!
@noiob @emmy I wouldn't be surprised! Emulation performance was going to be a key requirement for a smooth transition, and that's very much how Apple goes about core API implementation: if something can be improved by putting it in silicon, and it's justified, they will.
