They are inferior in performance and performance/power and if they have any advantages in performance/price no-one is interested in the absolute difference in cost.

That is all important but the ultimate roadblock is software.

The vicious chicken and egg question of getting an installed base for a
server architecture without software simultaneously with trying to get
ISVs to create software versions for a server architecture without an
installed base.

This held Alpha back in its day and suppressed uptake of Itanium.

ARM server pom-pom shakers seem to think that once you got Linux
and gcc support for ARM64 then Bob's your uncle.

Someone has to make a $10B bet over 5 years that the world needs
ARM servers and provide 1000's of free boxes to many ISVs and PAY
them millions to create and market ARM versions of their applications.
Even then it would at best establish an ARM64 software base a tiny,
tiny fraction of x86's.
