I wish apple would consider creating a rack-mount server to compete with Intel. They clearly have the silicon expertise to mint their own CPUs. I realize this isn't a sexy industry with lots of growth, but neither is the phone market anymore.
I don't really see them doing it because it's not somewhere they can really get away with their usual "we control the whole stack and you can only run our software on our hardware (legally)" mess they pull with macOS.
Samsung figured this out already. Their proportion of revenue from phones is decreasing while their semiconductor business is growing leaps and bounds.
