Intel is threatened with death.Regardless of any of this, I doubt that Apple is a significant threat to Intel or AMD. They are not interested in selling their chips to a third party, they do not target the server market, and they only offer products in the premium consumer segment. I think that long-term Apple might dominate the premium consumer as well as the mobile workstation and desktop video editing market, but I doubt they will surpass 15-20% of the PC market share.
The whole world is waiting the M2 to see if X86 will be totally dead in 3 years.
NVIDIA has buy ARM Holdings, Microsoft is working harder than ever on the ARM Windows version and even Intel is planning to open new factories to manufacture ARM chips for others.
The whole silicon market could change beyond M2, and Intel could survive with different business model if want to be the giant it is today (ahem! IBM…)
