Yup; or potentially just purchasing a fab from them, given that Intel has signaled they want to leverage TSMC more, and much of Intel's remaining value is wrapped up in server-grade chips that Apple wouldn't be interested in.
But also; Apple is one of the very few companies at their size that seems to have the political environment to make, and more importantly succeed, at decade investments. The iPhone wasn't an obvious success for 5 or 6 years. They started designing their own iPhone chips ~the iPhone 4 iirc, and pundits remarked: this isn't a good idea; today, the M5 in the iPad Pro outperforms every chip made by EVERYONE else in the world, by 25%, at a tenth the power draw and no active cooling (e.g. 9950X3D). Apple Maps (enough said). We're seeing similar investments today, things we could call "failures" that in 10 years we'll think were obviously going to be successful (cough vision pro).
> the M5 in the iPad Pro outperforms every chip made by EVERYONE else in the world
No, it does not. The core inside the M5 is faster than every other core design in single-threaded burst performance. That is common for small machines with a low core count and no hyperthreading.
The chip itself does not outperform every other chip in the world, nor is it 10x more efficient than the 9950X3D. That's not even napkin math at that point, you're making up numbers with no relation to relevant magnitude.

Definitely! But I'd recon they would want to bootstrap that part of their supply chain as soon as possible? Say China does invade Taiwan, suddenly their main supplier is gone and the Intel capacity mostly goes to military and other high margin segments. If they instead own Intel they not only control the narrative but also capitalize on the increase in Intel's value.
