ARM hasn't taken off in the datacenter. I'd argue it won't now, simply because RISC-V already exists, and with the extensions in the current spec, the ISA already is datacenter-ready. Chips will follow, and then adoption. Nobody's gonna take the migration hit of adopting ARM now, because datacenters aren't stupid enough to opt into ARM lock-in when they can just stay on x86 until they can deploy RISC-V. It really is that simple.
