ARM has gotten very good, and is definitely competitive with mid-range x86 while offering better performance-per-watt, but it is still not competitive with high-end x86.

Depends on the task and what you're measuring.
My M1 (standard) CPU is definitely faster than my Ryzen 7700x on some tasks, and it blows it away on perf/watt.
Those are both mid-range CPUs in standard consumer configurations, and I agree ARM does very well in that segment, and it does even better in the low-power/mobile/embedded segment where x86 is practically non-existent (recent gaming handhelds notwithstanding).
However, high-end workstations, compute-focused servers, and supercomputers, which use extremely expensive and power-hungry x86 chips, are a different segment, one to which ARM currently has no direct answer (and some might argue it shouldn't have one because such wasteful things shouldn't exist). This segment once had a number of competitive RISC players, like POWER and SPARC, so I don't think it's unobtainable for ARM.
What are you talking about there are arm supercomputers.
There's at least 2 in the top 10, and the fugaku was the fastest in the world for a couple of years between 2020 and 2022.
