Agreed - ARM put x86 on the clock, and Apple Silicon - the best implementation of ARM yet - is the death knell of x86. Every opinion to the contrary feels like cope, because it's coming, and fast.
A CPU is not a computer. Apple does not sell its CPUs to other manufacturers. A single vendor cannot supply solutions satisfying every person and every business requiring computers, no matter how good their tech is. Fast ARM merely keeps Apple relevant. It is not such an unfair advantage that everything else dies.
