Against whom? Classic desktop builds don't matter anymore, PC sales never fell so low. Not even the performance is what's needed. It's all perf/watt. x86 - which is all they have, beside some side hustles and cemented deals - is fading fast.
Yes, this will change over time. Unless there's a compatibility layer that's perfect though, I don't see this whole "x86 will be dead in 5 years" argument. That's what they said almost 15 years ago.
