The reason why Apple in 20 years turned from being 90 days away from bankruptcy to a revolutionary machine and most valuable 2+ trillion dollar company in the world is not because of HW ops or anything else, it's because of people.
While we know Steve Jobs had "issues with people", he also clearly stated:
> My model for business is The Beatles. They were four guys who kept each other kind of negative tendencies in check. They balanced each other and the total was greater than the sum of the parts. That's how I see business: great things in business are never done by one person, they're done by a team of people.
It takes a lot of people effort, talent and operations to achieve what Apple has achieved. So I think saying Apple is mediocre at people ops is unfair.

What an Apple P0 buys Apple might just be a bunch of favorable nerd press cycles. But that's not a problem Apple really has.
I am, however, convinced that with the right resource commitment, you could scale up a world-class research capability --- to potentially arbitrary levels --- without headhunting existing researchers, which is where I see the bottleneck right now.
Or, I mean, Apple could just rewrite their OS infrastructure in a memory-safe language. If I had the two options, I would put all my chips on the language change.
(I think P0 is extremely cool and valuable to Google in a bunch of ways and would be thrilled to see more major vendors try to replicate it, even I doubt they'll be successful).
And they are also moving all kernel extensions to user space anyway.
