When Jobs returned to Apple, the Apple he wanted to preserve was "Give people delightful products" not the Apple of "Mac OS was just great the way we shipped it in 1984, all we need going forward is an update System 7".
Is Gellsinger's vision of Intel "we are defined as 'we make the best CPUs, period'"? Or is it "we make x86 CPUs, period?"
This is, IMHO the only question that matters, but it's also the one that no-one is answering. Making some products at TSMC, taking Apple (and ARM and AMD) seriously; these do not matter. What matters is WHY you think Intel went wrong, because that shapes what you do differently going forward. IMHO an Intel going forward that designs CPUs in the same as today maybe beat AMD, but it won't beat Apple and ARM, regardless of whether it's using TSMC's process and whatever fancy chiplet, EMIB, and Foveros packaging it cares to use.
