Considering how well Apple's M1 is performing, I suspect within 10 years the majority of new desktops and laptops sold will be ARM-based, with both Intel and AMD having to either adapt or languish.
I think the overall trend is still accurate and in either case ARM + Nvidia is (or would be) a compelling provider of hardware but the segment of the market that needs/relies on X86 architecture does seem to be shrinking.
