The aarch64 ISA has left cruft and legacy than x64, with all unoptimal support for the complete history of SIMD evolution over several decades... On one side, I think this switch is a good thing for the industry, as I always believed that ARM was a better choice and that we should get rid of the legacy at some point. On the other hand, Apple is again tempted to play in their own garden, with a complete disregard of standards and interoperability. They're doing that with Metal, they will certainly do the same with their custom silicon.
