The only real (technical) moat that x86 has is backwards 
compatibility (and windows).

For raw performance the instruction doesn't make much difference 
(if any) other than in microbenchmarks here and there. I think 
Arm has some advantages in terms of perf/watt but I don't know 
any exact figures (e.g. the things I'm thinking of might not 
actually matter)

The best laptop processors at the moment are Apple's Arm chips, 
for example. Microsoft similarly are making another big push for 
Arm hardware at the moment.

As for HPC: Quite a few Arm supercomputers in the TOP500 these 
days (e.g. fugaku)
